AutoCad 3D :: Separate Polyface Mesh At Particular Point
Jun 8, 2011
Here's the file:
[URL].......
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 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 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 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 have a rigged single mesh character, but now for a video games i need to separate mesh in submeshes. (For example i want to separate the right and left hands from the body). So how can we break the mesh without breaking the rig and the vertex skinning?

I would like to use the same bones to skin a mesh in two different ways. I would like the first weight map to handle how the mesh reacts to the influences' transltes and rotates, and a second map that handles how the mesh reacts to the influences' scale.

I am attempting to apply multiple textures to a garage (both inside and outside). I have been able to create two separate uvw templates for the inside and outside using an editable mesh but the textured templates are not being applied to the model correctly. how can I detach the editable mesh to form separate objects?

I am running C3D 2010.
Somewhere along the line, someone in our office made our template import points into separate layers based on the RAW Description. I would like to un-do this. So far, I have deleted every point style & point label style except for 'Basic'. Inside of 'Basic', the layer is 'V-NODE'. However, some of my points are still coming in on layers like: 'V-Site-'(Raw Desc).
I'm about to start from scratch on the template, however, I'd like to avoid that because of the array of styles that are in it.

How do you add the motion path of a tracking point to a clone stamp without the clone stamp assuming the same initial/continuous positions of the tracking point?
Is there a way to keep the clone stamp's initial position and then add the path onto it?I am using the clone stamp to remove unwanted duct tape that was used to keep lights on a wall.

I have an assembly that has somewhere a hole with a round bar that exactly fits in this hole. But when meshing the assembly, the mesh of the hole and the mesh of the bar are different.
The result is that the different parts do only seem to touch each other at the edges of the mesh, resulting in high stresses.
See picture.
I tried to made a derived part from the assembly, but that one does not finish meshing. After 48 hours, the progress bar is still half way. While the one above did finish in about 15 minutes. What can I do to make the meshes match?

I'm creating an iPhone 4 case so it has a logo on it for my teacher. I got the case from thiniverse. It was a polyface mesh. i tried to subtract from it but it didn't work. I tried convtosolid but it didnt work. I exploded them and selected the outside shell and extruded all of the objects inward. Then when i tried to union them together, some of them would union, but not all of them together. im trying to export it as a .stl so I can use it with a 3D printer...
I'm using AutoCAD 2010 Educational version.

I thought they were supposed to appear when the Polygon shelf is selected? I don't see them. In fact, when I select different shelves the menu items on the right half of the task bar don't change at all. Is this normal?

I need to find a way how to insert a point or a * on the center point of a hole and put it on a different layer. The reason for this is - I am a CAD tech for a welding shop and we cut parts out of steel and we use the dxf file format for our plasma table to cut parts. For example : if i have a 1 inch thick plate and want to put a 3/4'' hole in the plate the hole will be distorted because the hole is smaller than the material thickness. For these situation we can use the plasma table to burn a point or a dot on the center point of the hole. But to do this the point or dot must be on a different layer in the dxf.

Im still new to Civil 3D and i would like to know how to connect inported points using 3D polylines. I imported my points from Excel in a PNEZD format. How do i get the 3d poly line to snap to my points so I can Connect them? someone mentioned using a feature line to connect the points but im not sure how or what that would do.
