AutoCAD Inventor :: Offset Surface For Parts Too Complex To Shell

Jul 24, 2012

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.

AutoCAD Inventor :: Ribs On Curved Surface / Trimming To Complex Surface

Feb 28, 2013

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.

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.

AutoCAD Inventor :: How To Engrave Words Onto Complex Curved Surface

Aug 16, 2012

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?

AutoCAD Inventor :: 2 Sheet Metal Parts - Joining Revolved Surface?

Jun 18, 2013

I have 2 sheet metal parts, both have been revolved using an angle of 359.9deg so there is a small gap to weld. in the assembly I copied one as a surface onto the other part and  I want to scuplt it at the intersection of the two.

The problem I've come to is that the small gap in the surface is preventing me from deleteing the upper part of the cut, how can I make the surface a whole so there is no gap in the cut?

AutoCAD 2013 :: Extruding / Offsetting Complex Surface

Jan 7, 2014

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?

AutoCAD Civil 3D :: Link Offset To Surface?

Oct 10, 2012

When I use link offset to surface and attach on left side, still extend to right.  I am targeting a slope stake line polyline that exists on both sides of the roadway, works fine on right side. Documentation indicates that a negative offset value is needed to use to the left.  How do I use negative value and target a polyline?

model (1) is the result on the left

model (2) is the correct result on the right

AutoCAD Civil 3D :: How To Create Offset To Tie To Surface

Aug 17, 2013

I'm creating a containment dike around and island.  I want the berm to tie down to the existing surface, then offset from that tie point 21' to the surface again.  I can do an offset from Baseline, or a tie to an elevation in a profile.  What I can't do is make the offset 21' from the tie location over an additional 21' to another tie point on a surface.

AutoCAD Civil 3D :: Offset A Surface Perpendicular To All Grades

Apr 7, 2010

Any way to raise/lower a surface, but is there a way to offset a surface basically 1m (to make it easy) perpendicular to all grades? Because when you raise/lower a surface, if you have a 3:1 slope, it will raise/lower it vertical 1m or so, but then the perpendicular distance between the 2 surfaces is less then 1m.

AutoCAD 2013 :: Converting Complex Solid Surface To Solid Model

Aug 12, 2013

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?

AutoCAD Inventor :: Error When Trying To Shell A Part?

Apr 22, 2012

When trying to shell a part i get the error: the attempted shell operation was unable to solve for a vertex....etc. i have attached the problem part file, of which the drawing is a fairly complicated frame (a chassis concept for a 3 wheeled race car i am designing)

How the part was made:It was created in an assembly using the frame generator tool and then converted to part file using the shrinkwrap feature. When using the shrinkwrap command, i selected: single solid body merging out seams between planar faces, All hole patching, break link, and remove all internal voids. and then when trying to shell i get the error message when selecting a wall thickness of 2mm.

i cant understand why the shell feature does not work as i have successfully shelled a very similar part file (with only slight differences in geometry from the file attached in the same way as what i am trying to do with this part). i can provide this part file upon request or the assembly file from which either was created. i need to shell the component in this way so that i can run accurate FEA (stress analysis) for crash simulations on it

I am using inventor 2013 (64bit OS)

AutoCAD Inventor :: Making A Shell Of A Mesh?

Dec 22, 2012

I am trying to make a shell of a mesh feature after I have upscaled it.

I do not think the regular shell technique will work as my mesh feature has hundreds of surfaces. So, I decided to open the file with my part in it and then derive the same part but a little bigger using the derive button. I would then subtract out the smaller, original, one to make a shell of the bigger, derived one.

Unfortunately, when I use this method to upscale, the 2 objects are not concentric so I cannot make the uniform shell that I want to.

I have attached the file of my mesh feature in case you want to see it. not that you will have to convert the object you see on my file into a base feature before doing anything with it. I did not because it would have made the file to big to attach.

AutoCAD Inventor :: Shell Command On Sphere

Aug 22, 2013

I have a funnel with a curved top.  I'm trying to project an inset of the border onto the curved surface and use the shell command to create a hollow funnel with an overhanging lip.  I have projected the inset successfully, but cannot select the resulting smaller face, just the whole original face.  

A similar problem that I tried while attempting to figure this out was shelling a sphere.  2d sketch -> 3d sketch project onto surface, and try applying shell to the resulting "face".  However I can only select the whole face when trying to shell.

AutoCAD Inventor :: Splitting Sections Of A Tank Shell

Jun 1, 2012

Is there a way to use the Split Solid tool to partially split a circle and have multiple solids after.

Ex) I would like to cut the tank at the 180 and 270 deg marks. Using the split tool still cuts through 0 and 90. I tried drawing a line from a top view that started from center going through 180, but it still goes through 0 as well.

I've attached an example shell of where I would like to have 6 solids after.

AutoCAD Inventor :: Shell Feature / Removing Any Outside Walls

Sep 17, 2013

Using the shell feature. I have used a bit in the past and its always done what I want. This go around what I want is to shell without removing any outside walls, which it does no matter I seem to try. I can easily add a new outter wall back in, but if I can shell without removing an outter wall it would be just that much cleaner in my tree.
