AutoCad 3D :: Extruding Shapes Of Shelves
Jan 7, 2014
I am in the process of drawing this bookshelf:
Bookshelf.jpg
As already visible on this picture I am having trouble with extruding some of the shapes of the shelves.
The tricky thing is what I have been doing differently with the one shapes where the extruding leads to the desired result and the others where it does not work. I have been trying different things: changed the shapes from splines to polylines etc. Does not work...
I´ll add a reduced version of the drawing here: the original shapes are on layer 0, the extrusions on 0 - X

The problem I'm having is presspull/extrude irregular shapes.
I have some really weird, irregular shapes that's consisted of fillets, lines, and arcs. For some reason I cannot REGION it. But I can HATCH it, and give it a solid inner part.
My irregular after being filled, can't be extruded. When I try extruding it, the command line goes "This kind of shape cannot be extruded", without any explanation, or keywords.
Then, if I try to PressPull, it only PressPull the outline of the irregular shape, without pulling out the inner bulk part.
Then if I try to do anything more, my AutoCad likes to go "About to regen -- proceed?" error.

I've created an object containing several shapes in Illustrator CS6 and exported it as a DWG, In Autocad 2014 I've exploded the block using XPlode command, now I want to extrude this shapes so I can create a geometry and start doing booleans and so one.
When I click in the Extrude option and select any of this shapes I get an error saying that objects of this type can not be extruded. I'm completely stuck I've been going back and forth from illustrator to Autocad 2014 and I can't find what's wrong.
P.S. The shapes in Illustrator have no stroke or filling so you will have to "Select All" to see the whole thing. The DWG and AI files are inside the attached zip. The DWG has been exported using "File > Export" w/ "Maximum edit-ability" from Illustrator.

About 1 in 3 times I start up Maya 2012, some of the shelves are either missing or are empty. For example, sometimes the "Polygons" shelf is completely missing, or else it is there but its contents are empty. If I close Maya and restart it, then they shelves will load up fine. Is there any fix to this?
I delete my preferences and start with new ones. This is a very fresh install, and I also had this problem with a previous install of 2012. And it does load up correctly sometimes so the preferences should be correct...right?

I'm doing a small 3D assignment for class, and I need extruding these trusses in my drawing 2". I'm aware that they need to be a solid polyline object in order to do so, however I can't seem to figure it out!
Here is the file:

I have the need to curve a region, then extrude it, is this possible?
The region is a flat view of a plasma cut plate with lots of holes/shapes that then gets rolled, doing it the way I describe would exactly re-produce in cad how the finished physical product comes out.

I am starting up my class again using AutoCAD Civil 2011. I want to extrude a circle or just a closed pline to a solid. I have done this many times before, but now it is not extruding to a solid, just a "Surface Extrusion". My commands are C:circle; C:region; (shows as filled circle and confirms it is a region); and finally C: extrude ; when I extrude it it is not a solid but rather a hollow "Surface Extrusion". Is it a function of 2011 and something I have turned on?

I am having trouble extruding(cutting) a shape into a cylinder. I want to cut the cylinder with a certain shape but I want to cut it tangent to the cylinder instead of just straight down through it like a front view.

I'm having trouble extruding a profile i have created. Get "Cannot sweep or extrude a self-intersecting curve" error. I have used the overkill command to find any duplicate lines. Trying to extrude along a straight line.

I'm setting up so isometric views with legacy hidden settings so it properly displays as it would in real life. I started out by making 2 rectangles (one 1/4" bigger than the other) and centered them together.
I then turned it into one polyline so I could extrude it.
But now it thinks that it's one big chunk of metal in the center, and not hollow. I don't know how to get a hollow piece of something.
make a hollow object that had a wall width??

When I try to extrude this closed polyline (yes it is closed) I get the message "Cannot sweep or extrude a self-intersecting curve." I do this sort of extrusion all the time (closed polylines with various geometry) and usually have no trouble.

Is it possible to extrude a curved 2D surface to give it thickness? For example, if you were to draw a loop the loop shape but it was just flat, could you extrude it out to give it thickness?

I am currently working on a complex roof truss (kind of similar to the new roof in Kings Cross station) and have currently got it in autocad as thousands of lines.... I am hoping to 3d print it and require all the lines to be solid cylinders of which I can convert easily enough individually... Any way of converting them all to cylinders to save having to do this over 5000 times!!

I have tried, such as creating lines in a 3D sketch and projecting the geometry to surface, and creating a work plane, and both don't seem to work for me.... I'm trying to cut out a 5.8mmx14mm rectangle out of a cylinder. When I project the geometry to the cylinder's inner surface, I cannot trim the solid in order to extrude. I've attached the file.

I can't post the original files, but I have gotten permission to post jpegs of what I am trying to do.
My end goal is to fill in between the grey part and the surface. The surface comes from another part in the assembly, and I used Copy Object to get the surface in this part file. Ideally I would like to do something like Extrude> To Next and select the surface as my terminator. I have done this with success with curved surfaces, but not complex curved surfaces. Does Inventor not handle extruding to complex curves?
Another option I tried was simply extending this part out beyond the surface using the Split feature to trim the part. Again, to no avail. I also tried creating a subassembly of this part and the part the surface is derived from with this part extending beyond the surface, deriving it and subtracting the surface part so I could use Delete Face with the Lump option. No dice there, either.
There was a hole in the side of the surface where I am trying to extrude the part (it is still open on the other side of the surface), but I used Patch and it seemed to fill it in just fine.
How to get accurate fill volume data in complex assemblies.

I have been extruding bodies around parts, then using their verticies for the frame generator (to guard around complex machinery.I then suppress the body and am left with the guard frame.
when i go to get the mass for the part, it includes the volume of the solid body which was used to give the outline.how can i turn the material property to zero density?

I have a arc that is about 21.5 radius and .5 in width. My problem is that it is going on a bench that i have made and the corner piece needs to be cut out and i am trying to figure how to make this line look like an actual piece. I can extrude the piece to 21 inches tall, but then i need it tapered back to fit this bench were making.

i need to create a solid by extruding/offseting a spline surface (attached picture). The problem is, a solid created by simply extruding this surface "outside" would cross itself, so autocad does not allow me to do it (neither extruding, surface offsetting is working) I tried to make a cube then using this surface as a splitting spline - however a solid created this way is flat on z-axis. How can I do this ? Everything is fine with the spline as well as a surface - it's closed one. Obviously the problem is in the fact in the self intersection of the extruded solid. So maybe using it to split a solid is a better approach?

I'm having trouble extruding a fully constrained sketch. The sketch is a cross-section of a hollow cylinder that is splined on the inside surface (see attached part file). The line segments that create these splines seem to be grouped together because moving one line moves the others, however the sketch will not extrude.
I can't use the coincident constraint button to group the lines because they don't separate from each other. I also tried to use the close loop button but was unable to select all the necessary lines.
how I can extrude this sketch or make an equivalent sketch that is easier to extrude

How do I go about extruding an open polyline to create a surface? I am able to extrude a solid 3d from a closed polyline ( by creating a region first) but I cant find a way to do the same for surfaces.The autodesk.autocad.databaseservices.Surface class does not have an extrude method unlike the its solid3d equivalent. I am using autocad 2012 .

Coming from Sketch up to real big boy tools. I watched the tutorial videos and tried poking around a bit for this specific answer but came up a bit short.
What I'm trying to do is loft a face to a point. Easy enough. I've got my point established on an offset work plane, and I can just loft to that, however, I get nothing but straight lines. (First attachment)
An example of the ideal outcome in SketchUp is the second attachment.
I'm having the most difficulty trying to draw the curves along which I want the face to be lofted because, even as I sketch along my 2D plane, I can't snap the endpoints of my arcs to the endpoints of the face (or the point to which they'll all connect).

I am trying to constrain a point(on a different part) to the sketch(yellow) on the inside surface of the triangle part. If I try the constraint like how it is now, it only allows me to select one segment, not the entire triangular shaped line. It would work if inventor saw the sketch as one single element, but it of course does not. I tried making a 3d sketch of the inner surface and then constraining to that, but it did not work.

I need to design a 'stencil' of sorts - but it just needs to be an array of circles separated by a constant distance. its an array of 200 micron diameter circles separated by a distance of 500 microns each (between centers).
Its super easy to make this array, but when I try to 'pull' it into the third dimension, or extrude the array, I get an 'invalid' error. Or the highlighted objects just get 'unhighlighted' (for the lack of a better word) once i hit enter after selecting them all. Also, I made the entire array into a 'block' of easiness.

There is a method for extruding ignoring the actual active layer, so the extrussion result is the same as 2D base object...(and is not created in active layer) i forgot how coul i do this, is really useful
After Googling a lot i didn't get any result
