AutoCAD Inventor :: Cutting A Rectangular Opening In Polyface Mesh Surface
Dec 5, 2012
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 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 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.

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 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 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 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...
Ok received parts from a customer. It was ALL mesh features.I converted some of them(the mesh features) to Solids. Some would not convert to solids (converted to surfaces).
I need to have the COG show up correctly. Yes, I have a physical COG. I know where it is supposed to be.
I am trying to use this and several other parts (with mixed, Solids, Surfaces, Mesh features), in an assembly AND balance it all thru a common lift point.
How can I correct the COG of the individual parts, so that the assembly is correct.
I have work planes for the corrected COGs, but I am afraid that I will need to calculate the new COG for the assebmly.
This is a very old project and even with more knowledge in 3D, still unable to do it. I have a stool with incline legs using the LOFT command (Extrude with Path can also do it). Now I need to add a tranverse section. I wanted to have the tranverse section same dimension as the leg.
Given the inclination of the leg, it is impossible and futile to align ucs using 3 points or face because there is no 90 deg between the two edges. Further more given there is no extrude to face as in inventor, it is sound difficult to extrude between the "/" form and the "" form of the two legs.
D problem? On geometry, is there a rule to adapt here with respect to section dimension?
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'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.
How to drape OS Mastermap/DWG over Profile DTM Surface Mesh? I've been trying for hours and can't get it to work. I've looked at articles online and they are hardly any use as they show you how to do it properly.
I'd like to be able to create a surface or mesh from contour lines to give a better 3D representation of terrain than just contour lines. "Drape" seems to be the tool ACA, but I'm wondering if AutoCAD can do something similar. LOFT sorta works, but even then, I have to do it in sections, and I'm not really looking for a solid.
'developing' or 'unrolling' or 'finding the true shape' of a 3D surface? Something similar to Robert McNeel's Rhino3D's UnrollSrf command to flatten a surface. (Is a mesh better?)
I am drawing the frames for a wooden surfboard which has curved spars (the surface in question) which need rolling out flat to make a template. The surface is curved in the XY axis only, so in theory it should be developable.
my cs5 has just started ofter using for 6 months to have a mesh over each image. when I go to view extras is ticked which I untick but when opening next image its there again. can I get rid ot this altogether or stop this happening.
Is the attached possible? I'm trying to cut out the plaster wrap to a wall, but can't figure out how to do it.
I've had a look at using reference planes in the door family object, but they don't seem to be able to do this?
Simply checking the wall type to wrap at only the external insert isn't going to work as I want the recess in the plaster to be away from the door frame edge.
Is there a way to cut a solid into two pieces using a non-planar cutting plane? I have been tasked with calculating the volume of concrete damage in a chute block. I have a sketch of the damage on the chute block. I created the chute block as a solid and then drew the damaged area extents using plines. This created non-planar plines. Is there a way to get this to work that will allow me to see the volume of the concrete damage? I need an easy way to do this, there are 50 chute blocks all the same size but with varying degrees of damage
how I can add more volume to curved object surface? Say for example I have a plastic cup.You can think of this as cylinder object ,which was the shelled out using the shell tool and then had its base sealed.
Now at certain parts, I would like to increase the thickness and then blend it the rest of the surface(may be chamfer its edges) .
At certain parts on curved surface I would like to add an extra mm, I think if the surface was flat I would just sketch the shape, then extrude it by few mm and smooth the edges by doing a chamfer
But how can this be done on surface that is curved? Or multi curved for edges?
I'm designing a press for a skateboard similar to: Rib Press
I have the board modeled: (see attached)
Now what i want to do is generate those ribs as seen in the picture.
I tried creating a block that intersected with the board and tried to split the rib at the surface, but to no avail. I think the issue has something to do with the curve of the board in two directions, but i can't seem to get it right.
if you are having trouble visualizing what i'm asking about, look at this. I want to be able to figure out the exact shape of those center ribs to print and eventually cut out of wood.
It is not possible forme to add the fil because it is to large 1.8MB how can I poste then I like to know if it is possible to extend the button flat surface diameter ø12.5 up to the shaped surface. The result should be a total solid block whit a surface shaped hole.
File last up-date with Autodesk Inventor Professional 2013
I am a beginner when a extrude a feature and select a part surface for new sketch now i want is to offset that surface but i can,t there is + sign with mouse icon and something like fully constrained is written in down the window.
