AutoCad :: Export Polyface Mesh Coordinates
Oct 26, 2011
I have a series of Polyface meshes imported from a Revit project.
(If this is doable straight from Revit that'd be good too, but I haven't had any success with that)
If I right click on one and select properties, I can clearly see where each vertex has an X, Y, and Z coordinate. For the purposes of a research project, I'd like to be able to automatically export all these coordinates to any ascii format for input into an algorithm. The dataextraction command does not seem to be capable of this and only exports the number of faces and vertices of each mesh.

I have some topography I've converted from SketchUp to .Dwg and I was curious if AutoCad (or any of it's versions) had the capabilities of turning this series of meshes into a run-of-the-mill topographic map. For instance, a standard plan view showing elevation lines at say 2' intervals.
If any of the versions are capable I can definitely get the 30 Day trial and give it a go.

I created a 3D math surface using 3DPLOT. However my outcome is a polyface mesh and I need to convert it to a solid. I have already tried the "Convert to Solid" & "Convert to Surface" options in the Mesh tab but I get "Mesh not converted because it is not closed or it self-intersects." I also tried the f2s.lsp but I am unsure on how to select my object.
Here is my object: [URL]
It is basically a 3D plot of cos(x) + cos(y).

I'm trying to figure out if there's a way to separate a Polyface Mesh at a particular point. I would like to use the SLICE command but it's not working. I tried SUBTRACT on the solid but no can do either. Is there a way to do this?
I have a huge structural floorplan, and I want to divide it up into sections so when XREF'ed in my drawing I can load it in piece by piece, saving a huge performance hit.

I have a 3d model of a building and all of the faces of the building are of the type polyface mesh. If I use explode, each polyface mesh gets split into individual 3d faces. But, I'd simply like to replace each polyface mesh with a 3d face (not multiple 3d faces). Is there anyway to do this?
The reason I'm doing this is because I'm importing the building model into ray tracing software, but the software doesn't like the building when the faces are of the type polyface mesh.

I'm trying to figure out a way to convert a 'Polyface Mesh' into a mass element or some other solid. The Polyface Mesh was created by importing a .3ds model using the '3dsin' command. The .3ds file was created from exporting the model out of Max.

I have a 3D model of a steel construction with the assignment to create special views of it and 2D projections for manufacturing of each beam individually. I tried many commands like Flatshot ( which don't work cause its a complex polyface mesh, and smooth mesh only makes a additionally mess), Flatten with hidden lines ( lines are mixed and changed), the LISP command SUPFLAT, but the hidden lines appear in the projection. SOLVIEW and SOLDRAW create views in the paperspace, which when export as a layout, become a mess too. The Lisp command M2S also does not work.

I created something in Rhino and imported it in Autocad as .3ds file but the geometry is not a solid one but a polyface mesh and I cannot edit it with boolean commands, thus I cannot continue editing it...I found out that there is this plugin Mesh 2 Solid but it is not free and I cannot find a proper crack anywhere..I cannot find any other way to make mesh solid...

I have created a TIN (triangulated irregular network) of an existing survey in my terrain modelling software (12d Model). I am able to export (save-as) the TIN as 3D Face Triangles for opening in AutoCAD (2012) or similar.
My ultimate goal is to create a solid surface in Inventor. The surface has to be seemless (stitched) in order for me to create a new sketch and extrude to this surface. Finally giving me a part in Inventor that represents my ground. I would then want to use the same process to bring into Inventor all other Civil Design works created in 12d Model such as roads, earthworks platforms (including dams) etc.
I've tried stitching (Inventor and Microstation) without success. Inventor keeps crashing and Microstation looses data. AutoCAD (2012) won't let me create a polyface mesh from 3D Faces. I tried doing a mesh, surface union without success. Programs either crash or data is lost.

I have a dwg file of a section of a tunnel that has been exported from Microstation as a polyface mesh surface. What I am trying to achieve is cutting a hole into the surface. I am assuming that I cannot cut a surface directly, but need to convert it to a solid first.
I've searched this site and I have tried everything I can think of to no avail. Inventor does not seem to be able to convert the surface to a solid. Also, when I import the surface to Inventor, some of the triangular meshes are not there, and there are too many "holes" to patch them manually. I've also tried using lisps in AutoCAD, but on the surface and 3D faces after exploding it, but for example m2s.lsp or f2s.lsp do not seem to work.
I have also had the same file exported from Microstation as ACIS .sat, but version 18.0 is not readable by Inventor. Is there a way to convert the ASCII file to an older version?
I am using Inventor 2013, and I also have AutoCAD 2013 available.

I am looking for a method to export all the GPS coordinates which have been assigned to each point along with the properties of that point to an excel csv.
In our drawings, there are multiple columns and each column has four points and each point has X,Y,Z coordinates. I want to export all this information to an excel sheet.

We are a couple of students just starting at our finale thesis at the university. We got some problems that we can't find a resolution to.
We are going to use Ultramarine MOSES to simulate a ship. We got the drawings as 2d construction lines (.dwg) and 3d (.igs) of the ship, and need all the coordinates, x,y,z of all lines, to the coding in MOSES.
Our problem is to get these coordinates from autocad. We have tried to open the dwg in autocad and use dataextraction to get the coordinates without any sucess. We have also tried the igs without any sucess there as well.

Here is the problem; corridor and its surface, etc are designed but there is no "obvious" way to get coordinates in order to layout the road in the field. There is the option to get COGO points from corridor via "create COGO POINTS" / "CREATE GROUND DATA" but this option refers only to points based on baseline in any station of the corridor and not in any station i would like to.

I have a question about exporting layouts into the model space coordinate system. I have a lot of drawings created from view frame and sheet set manager.
Each drawing has its own layout and it needs to be exported into model space. But when I export the layout it places the drawing into 0,0 in model space.
Is there any way to have it placed at the drawings coordinate system, assuming its in CA-VF (California State Plane Zone V, US foot) ?
Can it also be rotated, including title block, if the the viewport has a rotation (if the north arrow is not pointing up)?
We need to export the dwg's into dgn's. Our client uses Microstation v7 and all drawings need to be in that format.
I know v7 is old but what are you going to do.

I’m trying to export from my drawing point X-Y position coordinates to Excel for use in programming a metrology that will measure at these locations.
When I use the EATTEXT command to pull up the data extraction wizard, it will export the positions & extracts the locations to a spreadsheet format. But coordinate numbers I get, seem to be relative to the World USC system & not the origin I align & set in the center.
Yet when I use ID Point, to check positions the coordinates of the points are correct & relative to the center origin. How to get the location coordinates relative to the center USC origin I've located in the center of my part?

I'm working on a stream restoration project and we need to determine the x coordinates and corresponding elevations along a stream alignment at certain sample lines. The centerline of the stream's alignment has been created as well as sample lines for cross sections at 50' intervals. We need the coordinates & elevations of each sample line (cross section) exported into an excel/txt document.
For instance, at station 1+00 of the alignment we have a sample line. We need to know to the right and left along that sample line the corresponding elevations and that x coordinate) from the alignment. Primarily, whole contour intervals but more information would be useful as well. I was hoping this could be automatically generated.

I am just starting learning lisp, And I am looking for a fast way to select multiple objects (usually circle) and export their coordinates and ID into a excel sheet through lisp programming.
As you might see in the attached drawing, the red circles are objects wanted. I have been trying to export their coordinates as well as their IDs in grids, e.g D28, Easting: Northing: . I still haven't found a good way to export ID for each circle.
As my code doesn't work, I wonder what's the most effective way to detect errors in lisp
