AutoCad 3D :: Extrusion To 3D Solids?
May 13, 2013
I'm trying to understand extrusion to 3D solids better. This started when I drew a joined, closed 3dpolyline and found it wouldn't extrude (the shape titled 3D POLYLINES 4 sides joined, in the attached DWG), even though everything lies in the same plane (z=0). It gives the error "segment chord not perpendicular to normal". A chord is part of a circle, and there are no circles in the .dwg, so I don't understand the error. If you join only 2 or 0 sides, then at least 2D extrusion to a surface is allowed, but not if all 4 sides are joined, i.e. one 3D polyline.
If I draw regular polylines overtop the 3D polylines, then join and close them, it extrudes into a solid. This suggests that 3D polylines can't be extruded into a solid when regular polylines can, yet if I draw some scratch 3D polyline geometry that is joined and closed, these 3D polylines will join. It's as if I've found some secret shape that AutoCAD refuses to allow extrusion on.

I have a multibodied part (roughly 700 parts) and I need to do a cut extrusion. The problem is that when I'm cutting through a hundred or more solids I might miss one if it's close to the edge. I though, no problem I'll just go back to the extrusion command and add those solids I missed. Problem, the program only lets me select one solid and undoes all I had previously.

I need to do a cut extrusion on a multibodied part and need to select the solids. As of right now I have to select each one individually rather than doing a drag box or something like that. how I can do this fast, I've got a multibody part w/ over 1000 solids (I didn't create it, yes I know this is probably excessive).

When I try to select several solids for an extrusion cut/interference I can do so fairly quickly by selecting all of them in the browser so long as the extrusion is set to "all" or "distance".
For some reason when I need to do a "to" or "between" I have to select them one at a time. Every time I select a solid the select solids options returns to the input so that I have to select one solid then press the "Solids" button and select another one. This tends to do the same thing if I create an extrusion and then want to later modify the solids taking part in the extrusion. Is there an option I can turn off?

I am a bit new at 3D drawings, for many years it's been only 2D files used for .dxf purposes. My method is using "3D face" and them "extruding" to the size I want. When I view my layout or model, my 3D objects appear to be solids, but show some transparency. When I preview or print, they only come out as lines. How can I make these objects solid and print them?

How it's a 3d problem I though I'd ask anyway) but my pic is my problem (in red). How to get the curve in the solids (inside the red). I tried fillet but that didn't work .

I have a single-line riser diagram in 3D I want to flatten to 2D. things like super flatten and such don't work because I'm not using solids, just single lines.

I've been trying to convert 3D dwg models to 3D dgn models without success, using AutoCAD 2012.
The DGN either displays the solid, which isn't visible in a Microstation extraction or it just exports the centrelines/linework and not the solids.
Is this possible in newer version ? i.e. 2013/2014.
I've tried the export to ACIS .sat file and that works fine, but it moves everything to the same lavel/layer which defeats to object of seperatng the items in the first place.

I am having a bit a troubles with importing 3D solids to Inventor.
When I make 3D solids myself with autocad 2012 it works fine, but these solids I got appear scrambled.

I was wondering if it is possible to have 2 solids in 1 part and being able to pick which one I want to see in an assembly and which one I want to see in a drawing?
I have a leafspring that should show up unbended in the drawing (for the supplier) and bended in the assembly (for visual correctness). (I used Reference Sets for this in Unigraphics.)
I'm using Inventor 2012 (64-bit) with SP1 installed.

Where I am joining 2 solids (like plywood sitting in a dado joint), how can I have one solid be carved out where the 2nd solid overlaps it, without deleting the 2nd solid.
what SUBTRACT does but without the deleting.

Recently have had AutoCAD re installed and and am having trouble unioning and subtracting the two solids in the attached file. Other objects will occasionally subtract and union with these objects, but only occasionally.

AC2005, New to 3D and having a bit of a rough time (frustrating) getting objects to stay aligned from one Viewpoint to another. I move an object to what appears aligned w/ another object in FRONT view, but from TOP or any SIDE view, that object is way off in the background or half of the drawing away.

What's wrong with extrusion 15?
I deleted many features since the file was large, and many features got warnings, but extrusion 15 was the only one with warning in the original file.

I wanted to add an extrusion to an asembly. I was able to highlight the required geometry and create the feature, but is not showing up. In the browser, there's a red "up arrow" beside it. Why is it not showing?

First off if I update a sketch block in a derived part, how do I get the sketch blocks to update? Do I have to delete derived item, and rederive it?
Also if I modify a sketch block that is used for a extrusion, how do I get the extrusion to update? Do I have to delete extrusion and rextrude?

I understand how the current extrusion command works - You have a 2D polyline profile and you apply the extrusion command to that, getting your 3D shape.
However, I have a drawing full of different sized extrusions based on the same 2D polyline, and now I want to change that initial 2D polyline without having to manipulate each polyline separately. I thought it would be much better if the initial 2D polyline were referenced, allowing you to swap that inital 2D polyline with another 2D polyline. Is there a way - or a plugin - that is available to do this in AutoCAD?
FYI - the profiles are used in kitchen doors, and I want to be able to simply change the door profiles without resorting to re-extruding the whole lot.

I'm using 2D wireframe as my default view while extruding some solid pipes. Everything appears to work fine, but when I switch to any other shademode eg. 3D wireframe, some of the pipes disappear. In Navisworks they show up as listed objects in the selection tree but cannot be displayed and more imporantly do not get considered in clash detection.
I can't see anything different about the properties of the "hidden" pipes over any others that can be seen.
If I slice the "hidden" solids, then one half or both halves become visible like a normal solid again.
I have hundreds of pipes to model and clash so need to resolve what's happening here. Attached is a small sample file.

I have several IGES files that I need to make into solid models. I have been searching for days on how to do it in Inventor 2012 and everyone says how easy it is, but yet I have no luck. This file was created from a scanned mold and then made using a point cloud.

I have an assembly with some hidden solids in which are turned to invisible in both part and assembly but they show on the drawing.
how to not show these in the drawing but still show the unhidden soild.

Is there a way in Autocad to create a solid that moves, for instance I have a piece of equipment on a hinge and i wanted to show how the equipment looks in use and then how the equipment looks once it moves on the hinge.

I am trying to convert my corridors to solids and under toolspace-settings-corridor-commands there is a command called export corridor to solid but this option is not coming up in my toolspace.
I made this original file in civil 3d 2013 but am working on in in civil 3d 2014

Any solid shape just tend to go to the right no matter what angle you look at it and as it seems to go towards towards infinity . This is in orthographic view I might add. In perspective view the cube ends within the screen but it far from cubical and changes its appearance as you rotate it. As you can see in the pictures even the axis graphics down to the left is messed up.
Picture one is while I am extruding the 10mm cube. The big orange thing is the arrow used to drag up from the sketch.
Picture two is just the 10mm cube. As you can see the wire frame works just fine and it event hides the edges behind the solid.
I just installed the software on this computer so I suspect it is my graphics card that simply cannot handle the 3D solids. It is a few years old, a NVIDIA Quadro FX 540. The shadows does not work either, probably because I do not have shader model 2.0 or newer. do I have to scrap my computer?

I'm new to AutoCAD and I'm having trouble in one of my designs. I've attached the photo so you can see it. The problem is, I need the line that currently defines the left edge of my curve to follow the curve of the cylinder. I want it to be flush with the surface so that the line becomes a twist.

I have noticed that "Data Extraction" does not give you geometry information of a 3D solid such as position X, Y, and Z, and Length, Width, and Height. This information IS available in "Properties". Is there a way to extract this info to csv or some other format?

I drew several components in one drawing and saved them with WBLOCK. I opened the drawing into which I wanted to insert the blocks but they are no longer soilds. They are just the lines upon which the original soilids were based. What have I done wrong?
UPDATE: I purged the drawing and the blocks inserted correctly.
