3ds Max :: Unable To Create Solid From Polyline Model
Sep 5, 2011
I've got a DWG file generated from a software called 12D. It contains a polyline model of an embankment. I've imported it into Max and wanted to create 3D solids out of it so I can further manipulate this model and render.
I'm struggling to convert it into a 3D solid. I have tried the extrude and loft modifiers, but unable to get them to loft or extrude along the poly lines.
So I' thinking I may recreate the whole object from scratch vertex by vertex. How I can create a solid without recreating the whole object?
Attached a part of it for example here: [URL] ......

As part of a larger job we have surveyed the top of a dry stone wall. The client now wants that we make a solid for him from the surveyed points with a height of 2000mm (the drawing units are in millimetres).
A 3d polyline was created from the lines joining the points and I have that in the attached drawing.
I'm not looking for someone to create the wall, but I'm looking for the method to do it, as it will certainly crop up again with this new client. I've tried many ways in both AutoCAD and Civil 3D but just can't create the solid.

I'm trying to create a Solid 3d that is the extrusion solid af a closed polyline by a given height
I select the polyline that i do this
Solid3d s = new Solid3d();
s.CreateExtrudedSolid(selectedPolyline, new Vector3d(0, 0, 20), new SweepOptions());
but Autocad throw an Invalid Input exception.

Any program that can accept point clouds (which will be millions of points) from a 3D laser? Then we would like to create a solid model of the structures and piping.

I have just downloaded an educational version of Inventor. Although I can create sketches I cannot extrude the sketch to form a solid. The origin arrow heads appear over size and it seems as if the origin plane is being extruded to form a solid!

I have finally created the shell of the complex surface that you see. This is only a section of the part because I cannot show the whole thing for proprietary reasons. I formed solid surfaces using the network command. The propblem is that it will not convert to a solid because the surface seams are not "water tight." When the network command created the solid surfaces, the surface seams do not exactly match the lines so there are gaps in all the seams. I have tried blending, patching, etc. and nothing works. how to convert this to a solid without losing the outlines and the shape?

My problem today is that I made a Model of a Part of a ship using surfaces rather than solids because the engineer thought it would be easier to bring into ANSYS program for analysis but he is now having a problem with it and I am looking into converting my current model to solid. I can do it but the method I thought of using is quite long winded and we are working to a tight deadline.
1.open up the surface part
2.use "Offset/Thicken"
3.any clashes between parts make a sketch and cut away.
the problem is the amount of plates I have and the time it takes to sort them out.

We received a surface model from a vendor that I have patched up as best I can, it still has one hole that I can find that I haven't been able to fill. Ideally we would like to have a solid model, but I'm running out of time to get this done and the surface model we have would be good enough for our purposes IF I can get the yellow surface tangent lines to turn off or change their color to black.
I've attached a jpg of the surface model with the yellow lines and uploaded the model here: [URL].....

I've had a problem for a while now trying to extrude a 3d polyline into a 3d solid. The polyline is on different planes which is one cause of why it won't work. Instead of extruding into a solid it only does the sides making it a mesh rather than a solid. If its on one plane I know it will work.

I have polylines and changed the width to 3/4" and now the Plines are not solid (filled like a hatch) anymore? They are splined as well. I must have changed a setting somewhere and did not know it. AutoCAD 2012.

I have discovered a 3D polyline cant be joined to a 2D polyline and when i exploded 3Dpline then flattened it ,as recommended elsewhere on this forum,it seems its shrunk in length.The NC router I have access to has to use 2D polyline for the path of the cutter.wish i could simply fed the 3D object into the NC router software and that was all i had to do.

Any routine that would allow you to cut out an odd shape from a solid with the profile of a polyline?The goal would be to have all the pieces that are left, not subtract them out..

I've be trying convert a 3D solid model to DGN file and until now no success!
When I tried to export the model the error message of Figure 1 was returned. I'm using the settings of Figure 2. Is attached too, the DWG file for analysis.

I am trying to model I-Beams to s solid. I put 3d polyline around the front "I" then a path down the middle of the beam. I have tried extrude, sweep with aligned to path, and sweep not aligned - then put a patch on both ends. Use the command "surfsculpt" and it will not convert due to not being water tight. I delete the 3d poly and path line before patching.
We only have 2011 - Civil 3D.

I'm having issues in a particular drawing with moving a single polyline. I'm trying to move one polyline, but it instead moves all connecting polylines and some nearby polylines.
My specific example: I have a layer for the existing house, a layer for a hedge, and a layer for a fence. The polyline for the hedge is currently touching the polyline for the house and the fence polyline is next to it (but not touching). When I click on the hedge and try to pull it away from the house (whether from the end grips or midpoint) it will also try to move the polyline of the house that it's touching and the polyline of the fence that is closest to the hedge. When I try to move it using the MOVE command, the same thing happens.
I've tried shutting down CAD and turning it back on, opening it on another computer, flattening the entire drawing, and copying everything and pasting it into a new file. Nothing has worked so far.

I have a model of a boat from some database. It's build from 3D faces but I would like to make it a 3D solid with a thickness of 3mm.
I can convert the faces into a surface, but i can't seem to get any of the two models into a 3D solid. I have tried thicken, convtosolid and a lot of other options without luck.
I was wondering if I could make two surfaces, one smaller than the other, place them ontop of eachother and create solid between them?

I am using Autocad 2012 I have got a solid model with a lot of nuts and bolts, is it possible to get the nut to screw up the bolt (so it looks like it is moving up that bolt) also other parts also move it would be nice to make them look like they are moving to.

The problem is about drawing a solid model like the one in the attachment, and I have problem with the triangle, I tried a lot of things, but unfortunately it's not the same as it should be
My work is in the attachment.
and one more thing, as it's my first time with these kind of drawing I need to know what's the meaning (10 Drill, 20 C'bore) for a circle and how I can do it you can find it in the attachment

I am working on a research project that requires that I scan a cast object and shell it out to a width of .125 inches. I used my school's 3D scanner to scan the cast, and I have a good model. I've made it a surface and exported it as an STP and an IGS into Inventor. I used the Sculpt feature to make it a solid object, but then I could not shell it because a few flaws in the cast made miniscule holes.
I then tried to use the scanning program's spline feature to cut the cast into splines to loft in Inventor. However, this made 5 non-connected lines at each location, so I couldn't loft. How to create a solid and then shell with either method?

In attempting to use either 'export face as' or 'export sketch as' from a solid model in Inventor 2013 the resultant DXF file ALWAYS consists of PolyLines. This prevents other "downstream" software from properly importing the file as a DXF. Thus far the ONLY work-around I have found is to open the DXF in AutoCAD, Explode the polylines, and then re-save as a DXF from AutoCAD.

I drew a very complicated 2-D plot this afternoon. The most majority of the plot is composed of different straight lines, arcs. Then I used the polyline function to join them together to form a closed single polyline (Modify->object->polyline).
Later on I want to change something in part of the polyline. Then I used the 'pedit' again, I chose 'open'. But the whole polyline won't break into its original segments. I tried through all the menus, just cannot find the right tool for this purpose.
Does it mean I have to start over from scratch to redraw the whole plot?

I've created a bunch of lines which are touching each other but I can't seem to close them into a closed polyline area as I am trying to find the area of each individual profile.
I have tried moving the grips away and re attaching them, I have also extended all the lines and attempted to retrim them to ensure that they are closed, but none of this works.
The Fuzz distance is on 0, but I don't know if I am changing the profile in the units of millimeters so I am tentative to change this. But I just can't close the profiles.

I am in need of creating a solid drawing from my wireframe drawing in model space. I have never done any 3d modeling in autocad before it took me a few days just to get the wireframe of a staircase done! I have tried to render this object in viewport but it disappears after I click on it or move around, therefore I cannot see it in my paper layout. How do I make a rendered object stay? Also I want to plot this on 22x34in and 11x17in paper, how would I go about getting a high quality rendered image. I am using autocad 2010.

I'm using AutoCAD Mechanical 2010 and received a .DXF file that contains 'solid' objects. Unfortunately the next tool in my workflow doesn't understand 'solids' only polylines (and a few other basic shapes like circles, lines, etc). Is there some way to convert the object in AutoCAD?
I tried the 'boundary' command but when it asks to 'Pick Points' and I click inside the solid, it always gives the error 'Valid hatch boundary not found'.
What am I missing here?

I am not able to extrude closed polyline shapes. I get the following message:
Cannot create solid from open curve.
Cannot sweep or extrude non-planar objects.
Unable to extrude the selected object.
Other folks have opened my drawing – some can extrude, some get the same or similar message. I’ve tried re-building the shapes to extrude. It worked with one thing this morning and now it won’t extrude again.

I am trying to do some minor animation with a shaded solid model. I have tried mslide and a script... this make s very jerky, flashing animation.
I tried a lisp routine to move the object in small increments, again the motion is very flashy and slow, as it appears to struggle perhaps with the shading.
I noticed doing a move command, and moving the same object manually, dragging the object around the screen with a mouse makes for pretty smooth motion. Way better than what I was doing.... Is there a way to do this programatically?
