AutoCad :: 3D Polyface Mesh - 2D Projections With Hidden Lines
Aug 30, 2013
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 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 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 drawing objects (walls, platforms, etc.) in 3d made up primarily of extruded polygons. I want to be able to plot these objects in a way that hides all of the lines which are obscured by other objects. Currently I have my viewports set up with a 2D Wireframe visual style and a Hidden shade plot. This isn't working for me. I'm still getting all of the lines in the drawing visible no matter what.
Here's the strange thing: It seems to work perfectly fine in plan view, but not in front view. Also, it's worked fine in the past. It seems that the problem has gotten progressively worse over the past year or so.
I am using AutoCAD Plant 3D 2012 and working with the P&ID portion of the software. I created a block (to represent insulation with electric heat tracing) with multiple lines using multiple settings. All of the lines are on layer 0, the line weight is set to by layer. All of the lines have a linetype of by layer except one line which I need to be hidden. This block appears correctly on my screen, but when I print, the hidden line prints continuous.
My brain is exhausted and I think this is just a setting somewhere I can not seem to locate.
2d simple circle... I would like to define a circle using hidden lines. I also would like to have the hidden lines extend passed the circle by .25 of an in. I would also like to define the center of the circle aesthetically rather than just draw these hidden lines in.
maybe I was dreaming. Maybe I've gone round the bend. I seem to remember somewhere a check box that would show hidden lines in paperspace viewports. For instance, a through hole, or a cavity in something.
Been a while since I've done much besides architectural drawing, so maybe I'm hallucinating.
I also distinctly remember the monochrome plot style always printing in black and white, even in a PDF. Today, the objects in modelspace are in color, and anything in paper space is black and white.
What is up with that? I must be missing something obvious, because I've screwed around with this for an hour and can't figure out what I've done to cause this.
I need hidden lines in my drawings for the shop floor and the pictures below is the problem. It shows the hidden lines in the veiwport in paper layout but when I print preview or print i does not show them at all. windows 7 autocad 2007.
I'm opening a drawing created in AutoCAD 2008, which is plotting hidden arcs as solid lines. Straight hidden lines are dashed as normal. I've attached both the paperspace view and the plot preview to show what I mean. The outer radius is showing as dashed in paperspace view, but appears as a solid line when plotted. The straight line leading to it is dashed in both views.
Im trying to plot a 3D object in Autocad 2009 but can't remove the hidden lines. The "Hide" command removes the appropriate lines in the viewport and in the print preview but the print-out still appears with all the lines.
What I'm looking to do is show the hidden lines blocked by a part in a plan view but not all of the hidden lines. Ie. I have a top view showing a clearance. If I turn on that clearance a portion of the original part is not viewed. When I turn on hidden lines I now see every hidden detail of that part (I didn't turn on hidden lines for the entire drawing). I then have to eliminate all the lines I don't want which is both tedious and cumbersome. Is there a way to turn on just the lines hidden by a particular object but not all the hidden lines of the part.
I need to have hidden lines on a 3D object dashed. So basically I need all the lines but those lines that are at the back of a cube(wich are normaly hidden), they need to be dashed. See the attachment
I am very new to autocad and i am trying to duplicate a template in my text book. (Yes, i'm an old new student). I have a drawing that i am trying to add a hidden line to and when i pick my start point and then select my second point, the line will snap to the nearest corner instead of staying where i put it.
In my model, hidden lines look fine (ltscale is 1). But in my layouts (which I created with layoutwizard) the dashes and spaces are very large. How do I scale them down? (trying to use ltscale in the layout also applies it to the model so now lines appear as solid)
I am doing a .idw drawing of an assembly that I have several parts that I do not want to appear in the BOM parts list. I have therefore set these parts as Reference parts however this has caused them to appear as "hidden type" lines in the drawing and are even visible through other parts.
Is there any way to make these parts appear in the drawing "as normal" and not be listed in the parts list?
