AutoCad 3D :: Convert Polyface Mesh Into One 3D Face
Jan 21, 2012
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 have received a drawing drawn in a polyface mesh and I'm trying to convert it into a 3D shape in order to determine the volume and surface area of the shapes.

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'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'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'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 am trying to import a Polyface Mesh of a road plan to use in Terramodel. Terramodel handles .dwf and .dxf perfectly, but I seem to be having trouble preserving the elevations when importing. The polyface mesh imports in as polylines and without preserving the given elevations. I have used autocad in the past and have access to Autocad Civil 3d 2012 if need be.
Is there an import tool or command I am missing or unaware of that will allow the import to take place successfully?

I have a mesh that is made up of all quads and is a pretty dense object. I need to reduce the number of faces so can make it easier to work with and edit.
Whenever i use the reduce tool it takes my mesh that is all quads and distorts it to create a mesh that looks like the second picture above. How can i reduce my face or poly count without distorting my mesh so badly and keep only quads.

I've got a fairly complicated polygon mesh that I turned into a mesh. No problem. Then I try to convert to a surface and while the geometry is accurate the isolines change dramatically. I'm trying to bring the item into Inventor so that I can have a clean surface to work from. Unfortunately I get what you see in the picture. The top left is before converting to a surface. Bottom right is after.

I have a complicated 3d mesh and i want to use some edges in another software. The software accepts lines and i want to convert mesh to simple lines. I can make 3d polyline from the mesh but i can't convert it to line.
How we can convert mesh to line or 3d face to line or 3d polyline to line?

I have this chair in 3d but it consists of 3d faces and i can not convert all of them into surfaces or solids...only the faces that are on the same plane can be converted. Since the object is a little curved...i get the message"faces are not coplanar"...or something.

I received a 3D drawing but only need linework from it. I have flattened it out so I am able to export the linework. The problem is when I import the drawing into another software (Trimble Business Center), the lines are still 3D face and am not able to treat it like linework. Is there a way to convert a 3D face into line or polyline in C3D?

I just started with Autocad and I got a problem with creating a solid. The file is attached and as you can see I managed to make the form as a Mesh but from that point I can't convert it to a solid.

I have a series of Autocad Objects (3D faces). I need to turn the contiguous group of them into a SINGLE Autocad surface. I know next to nothing about vanilla autocad and 3D stuff. Seems there must be a way to make a surface out of objects. I would then use this resulting surface to carve a solid. DWG with 3D faces in it attached.
