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)

For a while now, I've been trying to shell a split game controller that will create the bottom part of the casing. However, every time I try to shell, a problem occurs "Modelling failure in ASM. Redefine inputs".
I've tried to find the source of the problem through supressing features, and when it finally does shell, the casing creates another problem that will not allow me to loft to get the proper appearance.

I am trying to shell a solid. I get error "No solution for vertex". I am thinking this may be due to where I swept two helix's and where they are connected is not a smooth transition. The file is too large to attach. How to make and attach a screen shot of my drawing.

I am trying to use Create Simplified part and during the creation process..I downloaded a model of a FD breaker off the Eaton Website in .stp format. I am simply trying to get a .ipt file of the model for my layout model.So the steps I did:
1- Open .stp file
2- Save .stp file as an .iam inventor file (ignore the prompt box "this is not a part file", that is from my logic rule for a part file)
3- once saved in inventor format, I click the simplify tab, select create simplified part, select a name and directory and press save
4- the .iam saves into a single part, BUT it is saved as sean.ipt, not the part number I assigned earlier and it is saved to the directory C:Users, not the directory I assigned in the dialogue box earlier.
Why does it do this every time I "dummy" down an assembly to a single .ipt file?

The goal of this project is to take a base part file, save new copies as needed, then modify the copies. They're rings for storage tanks that share the same tank diameter but differ in height and thickness. I have a SaveAsCopy rule in my template ring part that I run externally from my main assembly after passing down the new file names to the part rule. Since I'm testing a lot, I'm always deleting the parts from the assembly, then clearing out the new copies from my folder and running the rule again. Eventually after 1-5 times inventor starts giving me an error.
The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
The More Info Tab:
System.ArgumentException: The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG)) at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData) at Inventor.Document.SaveAs(String FileName, Boolean SaveCopyAs) at LmiRuleScript.Main() at Autodesk.iLogic.Exec.AppDomExec.ExecRuleInAssembly(Assembly assem) at iLogic.RuleEvalContainer.ExecRuleEval(String execRule)
The two other posts on here that deal with that error say it involves enumerating an array that is being changed and looking for an entry that is gone. I have a feeling it has to do with a left over variable (but this is all in iLogic rules so they get cleared at the end of the rule?), temporary files or remnant file references. It works again if I close the assembly and open it back up. Inventor 2013 SP 1.1

I have a surface model of a bin that I am going to use as a master for deriving sheet metal parts for each side of the bin. After creating Sketch 9, which defines the mating flanges of the sheets, I repeatedly get the error noted in the subject when I try creating a derived part from this file.
I narrowed the problem down to the sketch block I used to define the square holes or more specifically a dimension that appears in this sketch block. I originally drew the circle with the square around it within Sketch 9 and then used the Create Block command. Then I patterned the block along the edges and made the pattern symmetric about the mid point of the edge and placed the hole half way out on the flange. (Flange width is set as a user parameter "FlangeWidth"(1.5") and distance to hole is "FlangeWidth/2" or even just a raw value of 0.75").
Now once this dimension is added to the sketch it will also appear in the block editor for the 5-16 Carriage Square block. If this is deleted from the sketch and the block definition and the pattern of holes are left unconstrained in this one direction a derived part can be successfully made. BUT if a dimension is added to the sketch it will trickle down to the block definition and now a derived part will fail...
I realized that my holes are to be on the midline of the flange so I can constrain them there without a dimension and so I can work around this. I just didn't think dimensions to geometry not included in a block were added to the block definition.

I have a part that is derived from a surface skeleton ipt. The derived surface is thickened and then some holes are added. Then, when I try to add a flange, it gives me the error "Sheet metal features are not supported in multi solid body parts". My part is a sheet metal part and single body.

I need to shell out a Loft in the attached IV 2012 part file.The Loft i tried also as a new solid but the shell also cuts into the cylinder ( revolution 1 ) . I only want the 2 sides and bottom of the Loft to be Shelled, not the cylinder. What do i need to change to get the shell to work?

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.

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.

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.

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.

I have a blade housing that requires a continuos radius around the profile. It is not a full radius. When I shell the blade, it looks like the raidius wants to continue. I was told I had to use two fillets and the particial radius will not work. However, the continuous radious in the customers requirement. Is there a way to shell this part correctly?

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.

I'm trying to create a model of a Golf club head. I need it to be hollow but I am unable to do this using the shell operation or by creating a surface and thickening the faces. I created the geometry by lofting a series of sketches. I think the nature of the geometry may be causing the problem.

I'm not exactly sure how to verbalize this task, but I'd like to shell a solid by selecting 2 opposing faces amd maintain a center wall. Can this be done using only the shell feature?
Notice the solid below is hollow.

Having problem with a particular file crash/freeze/not respond whenever using the shell feature on Inventor LT 2013? I am operating with Windows 7. I have the AutoCAD Inventor LT 2013 Suite. Just bought the computer two weeks ago and just installed Inventor about two weeks ago also.
In any case, it seems the file of this model is corrupted, as I have never had a problem using the Shell feature before this and shelling other objects even while the corrupted part is open works fine. However, if the "visibilty" of the part in question is checked and i click on the shell button, the program immediately freezes. I am not sure how to work around this and I really do not want to start the entire part modeling over from scratch.

I have drawn an assembly of parts and now wish to line up the small hole in the large shell to the projecting pipe,i thought it would be a simple task of using mates (insert aligned) but this does not let me pick on the boundary of the small hole.

I set up our company log which gets embossed on most parts as a sketch block in an .ipt. The .ipt contains nothing but the sketch block. To use it, the designer only needs to derive the Logo.ipt file into their part and then use the scale setting to set the derived block to the desired size for that part. The result is a scalable set of line geometry that can easily be used for extrusion or emboss that is standard for all users. It works beautifully, that is until you try to use it in a sheet metal part in 2012.
For some reason, when this same part, which works perfectly in normal parts, is derived into a sheet metal part an error pops up stating that, "Selected part does not have any geometry that can be derived." Say what?
I was able to find a workaround by directly copying the block into the sheet metal part, but you no longer have the ability to go back and scale it if needed. Even more strange, when the block was copied over, it could not be deleted from the new part.
Is this just a bug with 2012? Why does it work in a normal part but not sheet metal?
