AutoCAD Inventor :: Extruding To Complex Surface
May 16, 2012
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 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 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.

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.

The problem: a complex curvy part will shell 0.5 mm but not 3mm - some of the surfaces fall inside the others.
A work around : Offset each surace (individually - not quilt) then stich & sculpt.
A program: To offset an enclosed surface, individual face by face, internally. Then manually stich to identify any errors & patch accordingly.
Note these parts have 100's of faces so the code would be useful - not sure how to always offset the surface to the inside of the volume.

In inventor 2013, how do I engrave and wrap some text onto a surface that is neither on a cylinder, a cone, or a sphere? I created the part by first drawing a cross section made up with the spline tool, then revolved it around an axis. I need to imprint two words on the part's curved surface. I sketched the words, then I tried using the emboss/engrave wrap feature, but I got an error message saying that emboss/engrave wrap can only be done on standard surfaces such as cylinders, cones, or spheres. How to engrave words on surfaces other than these standard surfaces? I also tried to extrude cut the words onto the surface, but the words don't wrap to the surface, and are not evenly imprinted onto it.
Also how do i make the letter's bigger when I sketch them? even though I put in large numbers such as 50 in the size box, the text does not appear big. Also, how do I increase the spacing between the letters?

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?

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 .

I keep getting this message. I know others have posted about it- but back int 2006 [URL]. The referenced link showing the solution is no longer available.
I read on an archived blog somewhere that is was a glitch in autocad2005. I am running 2010- so I don't get it. I really need to extrude these plines

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?

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'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

(Inventor 2012) I have a weldment. I can make holes and save, I can make revolved cuts and save. I can make chamfers and/or fillets and save. But if I try to extrude a cut (any cut), I receive an error.
Problems encountered while saving the document.
Error(s) detected while writing segment AmBREPSegment in database C:lah-blah.iam
Error detected while saving object of type MIxTransactablePartition in C:lah-blah.iam

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 have just upgraded to 2013, and there is one "feature" I find kind of distracting. When working in a part, I create a new sketch. When I extrude that sketch, Inventor automatically switches me to an Iso view. I don't want that. I would prefer to stay in the view that I established.
Is there a way to turn that off?

I have a shrinkwrapped file. Now the link is broken from the actual assembly and the orginal assembly is now gone. Now in this shrinkwrapped file, there is a portion that I want to isolate. Is there any way to delete / remove the other parts that i dont need? Extruding, sculpting and delete faces dont work. So far the only thing I can do is add extrusions to the part but not remove.

I have a shape that happens to have many nodes; it was simple to extrude it (inventor saw it as a complete shape) but adding fillets is another story. each tiny segment requires a click to select it. is there any way to simplify this — either through simplifying the path somehow or by selecting the edge in some other manner?
i saw a thread on the forums about imported 2d vector files with a similar issue. I did import my file but it came from rhino. everything is fine except this one issue. i guess i could go back to rhino but i would prefer not to.
i have attached a small screenshot of one area of my sketch.

I have a problem regarding a mechanical design. I want to make a pin move around a complex shape, always tangent to the sides of the shape. The point is not to have it animated, but I need the constrain so I can further work on the mechanical design.
I've attached a photo and the files.

There are several uncontrolled jumps during the movement, but in the end, after some delay, it's normal again.I can send the Inventor 2013 files to an FTP site.

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?

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.

Trying to create a fold/bend/flange along a curved feature. I modeled the part to view but would like to be able to model this feature in sheet metal. This is how it would be manufactured, probably in a die roll.

Is it possible to run force analysis on my part in Inventor? I have used the force analysis before, but never for something so complex in shape. My main issues are constraining the base of the part and applying forces. I tried thickening sections of the part in order to apply a force/constraint, but now Inventor won't recognize the thickened parts as connected to the main body.
On a side note, it won't let me attach my file, which is 122 MB. Is it too large?

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'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!

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.
