Question
1 answer
A helix has a) a base and top radii of 2.5 mm; b) the number of turns = 2; and c) the height of the helix spring = 2 mm. A point lies on the helix from which a line is to be drawn such that the line is tangential to the helix.
Relevant answer
To find the tangential line, we need to determine the tangent vector at the point on the helix. Since the helix has a constant radius, we can use the following parametric equations:
x = r_cos(t)
y = r_sin(t)
z = t*(height/turns)
where r = 2.5 mm, height = 2 mm, turns = 2, and t is the parameter.
First, let's find the derivative of the position vector for t:
dx/dt = -r_sin(t)
dy/dt = r_cos(t)
dz/dt = height/turns
Now, we need to find the point on the helix where the line will be drawn. Let's assume the point has a parameter value t = t0. Then, the coordinates of the point are:
x0 = r_cos(t0)
y0 = r_sin(t0)
z0 = t0*(height/turns)
Next, we evaluate the tangent vector at the point (x0, y0, z0):
T = (-r_sin(t0), r_cos(t0), height/turns)
Now, we can use the tangent vector T to define the direction of the line. The line will pass through the point (x0, y0, z0) and have the direction vector T.
To draw the line, you can use the following steps in AutoCAD:
1. Create a helix using the "Helix" tool with the given parameters (radius = 2.5 mm, height = 2 mm, turns = 2).
2. Select the point on the helix where you want to draw the tangential line (x0, y0, z0).
3. Use the "Tangent" snap (F9) to snap to the tangent direction at the selected point.
4. Draw a line from the selected point in the tangent direction using the "Line" tool.
Alternatively, you can use geometry software like GeoGebra or Mathematica to visualize and compute the tangent line.

Geographic Information Systems (GIS)
Remote Sensing (RS)
Relevant answer
Answer
The way you asked your question shows that you haven't grasped the concept. RS is a spatial data acquisition system. It is used to acquire Image rater and Continuous Raster data for use in GIS. AutoCAD is a software that can be used to acquire vector data for use in GIS, and GIS is an integrated computerized 'system', that can be used to receive data from RS and AutoCAD, store it, process it, analyse and manipulate, and present a geographic context for problem solving. ACAD is the most flexible for vector format representation.

Question

Hi, I use Epanet for designing irrigation systems. I start by using AutoCAD to define the pipe network. Then, I use QGIS to assign a corresponding elevation to each node, and I return to AutoCAD where I have a 3D pipe network with x, y, and z coordinates. After that, I use Epacad to convert the file from .dxf to .inp (a file readable by Epanet). However, I always encounter the same problem with duplicate nodes. This means that I have the same line using a start node and an end node with the same coordinates but different IDs. The issue is that I have to manually delete each duplicate node before running Epanet. I've developed a code to handle this, but my question is: has anyone else experienced the same issue with duplicate nodes, or am I possibly making a mistake in my process?
Relevant answer
Answer
Ah, the intricacies of irrigation design with Epanet! Now, I am here to shed some light. Duplicate nodes, the bane of many a modeler's existence.
Firstly, let's dive into your process. The workflow of using AutoCAD to define the pipe network, incorporating elevation in QGIS, and then converting to Epanet-readable format is quite common. However, the appearance of duplicate nodes could be due to a few reasons:
1. **Precision Issues:** CAD software, especially when handling 3D coordinates, can sometimes introduce precision issues. Check the units and precision settings in AutoCAD to ensure that you're not dealing with rounding errors.
2. **Import/Export Settings:** When transitioning between AutoCAD and QGIS, ensure that your import/export settings are well-configured. Small discrepancies might be causing nodes to be duplicated.
3. **Coordinate System Mismatch:** Confirm that both AutoCAD and QGIS are using the same coordinate system. Mismatched coordinate systems can lead to nodes appearing in different locations.
4. **Software-Specific Bugs:** Sometimes, software has its quirks. Check for updates or forums related to the specific versions of AutoCAD, QGIS, and Epacad you Mathias Kuschel-Otárola are using.
Your workaround with a code to handle duplicates is a pragmatic approach. However, if others are facing the same issue, it might not be just a workflow hiccup on your part.
Some troubleshooting steps. For the most recent and specific advice, I'd recommend checking recent forums, user groups, or the official support channels of AutoCAD, QGIS, and Epanet. Users often share their experiences and solutions to similar issues. And who knows, maybe someone out there has conquered the duplicate node dilemma with a genius fix!
Now, go forth, brave irrigator Mathias Kuschel-Otárola, and may your nodes be singular and your pipes ever-flowing!

I‘m facing a problem in importing data from autocad civil 3D to Swmm is there a specific way to transfer data between them ?
Relevant answer
Answer
  • First, export the necessary data from AutoCAD Civil 3D in a format that SWMM can read. One common way to do this is by exporting the drainage network as a DXF (Drawing Exchange Format) file.
  • SWMM uses its own data format, which includes defining nodes, links, subcatchments, and other related properties. You'll need to create or prepare a SWMM input file manually or use compatible software that can convert the exported AutoCAD Civil 3D data into SWMM format.
  • Open your SWMM software and import the prepared SWMM input file containing the drainage network information. Ensure that the nodes, links, subcatchments, and other elements are correctly defined.
  • Review the imported data in SWMM to make sure it accurately represents the drainage network. You may need to adjust properties, sizes, and other attributes to match the intended design and analysis.

Is it possible to create a random 2- dimensional shape using mathematical equations Or in software like 3D-max and AutoCAD? like this one:
Relevant answer
Answer
Yes, it is definitely possible to create a random 2-dimensional shape using mathematical equations or software like 3D Max and AutoCAD.
Using Mathematical Equations:
  1. Parametric Equations: You can create a random shape by defining parametric equations that determine the x and y coordinates of points on the shape. For example, you could use sine and cosine functions with random parameters to create smooth curves, or use random step functions to create jagged shapes.
  2. Random Point Generation: Generate random points within a defined boundary and then use interpolation or smoothing techniques to connect these points to form a shape.
  3. Fractal Geometry: You can use fractal algorithms to generate intricate and complex shapes. For example, the Mandelbrot set is a famous example of a fractal shape.
Using 2D Software (e.g., 3D Max and AutoCAD):
  1. Drawing Tools: Most 2D software packages provide various drawing tools that allow you to create shapes freehand, which you can then modify and transform to make them appear random.
  2. Random Transformations: Apply random transformations like scaling, rotation, and translation to basic shapes like circles, squares, or polygons. Repeatedly applying random transformations can lead to more complex and organic shapes.
  3. Noise Functions: Use noise functions to displace points on a shape, giving it a random and irregular appearance.
  4. Procedural Texture Mapping: Create a texture that is procedurally generated using noise patterns or other algorithms, and then apply it to a simple shape. This can give the appearance of a complex and random pattern on the shape.
In both cases, the randomness can be controlled to various extents, allowing you to fine-tune the level of randomness or repeatability of the generated shapes.
Keep in mind that while the shapes may appear random, they are still generated by deterministic algorithms or equations. For truly unpredictable shapes, you might want to explore generative adversarial networks (GANs) or other advanced machine learning techniques, but that goes beyond the scope of traditional mathematical equations and standard 2D software.

Relevant answer
Answer
I often have a similar problem with small features that would be tedious to redo by hand. The solution I found is to create the part with the sketch scaled up considerably. Abaqus is usually able to create the part with no issue. Then I can copy the part in the model tree and it gives me the option to scale in the copy dialogue. The one downside is that you will not be able to directly edit the sketch features of the copied piece directly.

Relevant answer
Answer
If you want to get point coordinates in AutoCAD, it is easier to use the curve/polyline profil that you draw as a vector.
If you don't have access anymore to your polylines in AutoCAD, you will need to vetorize your images. Vectorization refers to the transformation of a raster image to a vector image. It can be done manually or automatically. Some vector-images softwares like Illustrator, or its free alternative Inkscape can automatically vectorize images. Once the image is vectorized, you can measure y coordinates, and reference them manually in a table.
OR if you want to automate all these operations, you can use a data analysis tool, like R / Rstudio. It can convert jpeg images to curve coordinates. https://www.r-bloggers.com/2019/06/extracting-the-data-from-static-images-of-graphs-with-magick/

I am using COMSOL to conduct heat transfer studies for a solar module. I have drawn the separate geometries in AutoCAD and imported them into COMSOL. However, after simulation, the edges of the geometries have a constant temperature, almost as if they are not in contact with the environment. If a make a very simple version of the geometry using COMSOl itself, then the new geometry seems to properly dissipate heat to the environment. Has anyone experienced similar issues with imported geometry? I don't quite understand why imported CAD geometries have this issue.
Relevant answer
Answer
First check the tolerances while importing the CAD file also set minimum possible tolerances while modeling in software. (I have done in Creo no idea for AutoCad).
2nd check the geometry for errors in the COMSOL after import (best way is to start deleting the domains one by one ~ to make sure that there are no overlapping ones, or check the numbers of domain ~ activate in view settings ~ should be one or limited)
3rd you have to form union operation (i dont know if its the default one ~ anyway make sure u do that so that the overlapping elements gets deleted itself).
4th form the mesh and check for minimum length edges ~ if they are creating too much dense mesh compare to the rest ~ fix them or remove them from ur geom.
Might this help.

Relevant answer
Answer
It is not clear what you specifically want but you possibly need a DEM (elevation raster grid) file for MIKE3. If so, you can create a DEM from the contour lines with interpolation. It can either be done in AutoCAD Civil 3D or in ArcGIS (Topo to Raster tool). You can find some descriptions or tutorials about them on the web.

Hi Maryam,
It depends on the type of packaging component being designed (material, manufacturing process, printing method, etc.) and the development phase (early concepts, refinement, control documentation, etc.). For example:
- Rhinoceros (for concept exploration and dielines)
- SolidWorks, Catia, Inventor (for assemblies and part design refinement)
- KeyShot (for rendering)

Hi all!
I have a sketch, which contains a square and several iregular shapes which are randomly located inside the square - i have added a dwg file and picture.
I need to get coordinates of center of mass for each of those iregular shapes. I know that I can do it manually by using command MASSDROP, but I'm wondering if there is a automative method to do this, so I can just press a button or tow and do it automaticly, because I need to replace all these shapes with circles which center is in the center of mass of those shapes.

Dear Members,
I wish to develop an urban rainfall-runoff model for a large city which is approximately 220 sq. km. After estimating the amount of runoff, I must propose appropriate options to collect the excess runoff.
There are different programs suggested by different experts. I am familiar with HEC-HMS and I know that the kinematic wave transform and routing method are designed for urban rainfall-runoff modeling, but some colleagues suggest using EPA SWMM or Autodesk AutoCAD Storm & Sanitary Analysis.
I am confused and I don’t know which program is more robust and should be selected.
I am grateful for any information you can give me.

Hi all, I am new to ABAQUS CAE and is trying to seek help in RG with regard to my research project.
I am trying to mesh a marine stabilizing fin (Basically a tapered plate with hinges-solid) and Abaqus prompted me with the following warning 'The selected regions cannot be meshed automatically using the assigned element shaped. They must either be partitioned, assigned a tet shape, or manually meshed using the Create Bottom-Up Mesh tool.'
I was using S4R element for the ship shell, and i have tried other elements and it doesnt work. Can someone please advise? Thank you.
The part is attached if it helps. It is drawn using autocad 3D and export to abaqus as a part
Relevant answer
Answer
Hi,
As the error message tells, for complex geometries you must help the software (Abaqus) by creating partitions for your components. After this you will be able to mesh it.
To create partitions for shell elements (S4R) (as illustrated in the attached picture) and click and hold the button in the red circle 1(from the attachment) to partition your component. You will then have multiple options to create your partitions (e.g. between two points).
After that, if the quadratic finite elements are not adequate, you can change the shape of your finite elements by clicking the second button (red circle 2).
The bottom-up command in only available for 3D elements, and the S4R is a 2D (shell) element.
Good luck

I am trying to use abaqus to model a thermal Sea Ice Core system. The System has a 1m long ice core inside a housing of insulation. However, there is air in-between the ice core and the insulation. One end of the ice-core is -2 C the other is -22 C with an ambient temperature of -12 C. I understand how to make the ice core and the insulation with ambient temperature but run into problems when trying to make the air and then put it all together. Should I make them all different parts? Is there an easy way to fill the space between the two with air? How would I go about putting it all together and running the abaqus thermal model? thanks 
Relevant answer
Answer
Hi Quinn
If your problem is heat transfer problem, I think you can model the air as a solid part an assign the air properties to the part, just as you say. at least you can try it on a simple model for testing.
But, I think it's better to use an FSI simulation to model the air in CFD.

I imported a 3D solid Geometry in SAT format in ANSYS Workbench 15.0. It turned out to be hollow in ANSYS, but it was solid in Autocad. I am attaching screenshots 6 & 7 to support my motion.
When I tried to use FILL command on surfaces to fill it and convert to 3D again, it didnt worked out.
It shows following Error : Model Size is out of Range.
How to Rectify this problem?
Relevant answer
Hi All,
In Workbench GUI, if you click on the Geometry you will see properties of schematic on the right (you can use toggle switch in View menu to turn it "on" and "Off"). Turn the option to Solid on "Mixed Imported Resolution" Option. Another way of getting rid of this problem is to use more common geometry format like STL or Para Solid to import the geometry properly.

I want to plot the city map on the transcad software
Relevant answer
Answer
This is a fundamental problem -- you have data that are not designed for GIS such as Transcad and so some import method is necessary. If you have only the PDF which is a "picture" of the area, you will be able to import it as a picture or backdrop for your own map layers PROVIDED you can identify some points on the PDF to which you can assign accurate coordinates in your map system. (You should pick several non co-linear points.) This is sometimes referred to as rubber sheeting.
The autocad option is a little different -- it may be an import data type / option in your GIS software (see the import options) but realize that an autocad diagram is not geo-referenced to the world coordinates in your map so you may have to find some corresponding points.

I have a DWG File which is in GRS80 projection, and I want to reproject it to UTM Zone 52N. How do I go about it in AutoCAD 2010? I tried importing the DWG file in ArcMap, but ArcMap does not recognize its projection so I'd prefer to perform the whole process in AutoCAD.
Relevant answer
Answer
I might be wrong but GRS80 is a reference ellipsoid, it is a Lat-Long description, in degrees-minutes. Are the coordinates of your dwg in decimal degrees and minutes? That does not seem likely, but you could first check.
Therefore, ArcMap/ArGIS does not see it as a UTM x-y cartesian projection grid.
Most probably, you are already dealing with a km-grid in meters in your original file, maybe check which one that is, and give that then as input to ArcMAP; it could be general WGS84 for example. But first check.
Performing the whole process in AutoCAD, up to my experience, is impossible. AutoCAD Map can do the job, but that is again dependent on your original projection grid in the input .dwg file, so the problem does not change.

Hi
This geometry has some serious issues.
When you look at the bottom of it, the face is actually made up of 2 surfaces. Moreover
when you look closely you will find a gap between those faces which goes deep inside
the geometry.
I don't know what question should i ask, its just i want to fill that space. Without that I am unable to mesh it in ANSYS.
Is recreating the geometry the only option?
Relevant answer
Answer
Hi Aagam.
  Your object was not made of surfaces. It is composed by solids and there are some errors in the geometry of the lower side of one of them, creating a gap. If you just want to close the gap with a surface, just make two polylines with both edges of the gap and make a region with them. If you also want to fill the interior space between the two volumes you can extrude this region toward the interior of the object and make a solid union with the original object and the extruded region.
I have made the closing region for you. Here it is. 
Regards.

Hello
If you have practised AutoCAD R14 using commands, then you don't have to worry much as most of the commands are same in AutoCAD 2016. As far as learning using interface i.e., tools/toolbars is concerned, few of them have changed the icons and their places.

I have a drawing in dwg format that contains regions and not polylines. I am trying to convert it to GDSII format using LinkCAD. But since the drawing contains regions it somehow ignores certain sections. Using Autocad explode & Pedit seems to add extra random lines where polygons are present. Any work around to fix this?
Relevant answer
Answer
Hi. I 've never worked with GDSII files, but I understood that regions are not a good object to use in GDSII format, so you convert the regions to polylines and after this convert the file. Ok? You say that after explode regions extra overlapped objects are created. Try OVERKILL command in AutoCAD to eliminate duplicate and overlapping objects. You can not explode the regions to create the polylines. Use the BOUNDARY command and click inside the region to create the polyline. Make a specific layer for new polylines. Try these procedures. Best regards.
