Problem with 3D model exported from Inventor

Recommended Posts

Arvid93

I worked with a 3D model in AutoCAD 2012 and then I wanted to add some variable fillets so I saved the part to be filleted as a block and the opened it in Inventor 2012 using Open > Import DWG. I added the fillets and then I used the "Export to DWG" command. I inserted the part in AutoCAD again using "Insert". I exploded the block to a 3D solid and everything looked fine but the next time i opened the dwg file it looked weird at some places (see picture).

Does anyone know why this is happening?

I'd double check the geometry first. Maybe you have a "snippet" of something left over from some editing you did.

No, I did not misunderstand you. I still think you could have an errant piece of geometry. I'm not saying it was intentional; more like something you may have overlooked. It did not affect anything until you exploded the 3D block. I hope I am wrong but it is still worth checking isn't it?

 

I did not look at the YouTube clip.

No, I meant that I maybe had missunderstood your first answer because I was not sure how you meant I should check the geometry. I thought that you maybe meant that there could be solids on top of each other or some lines (Which I did not find).

Can you post the DWG here?

If it were me I might zoom into the area and do some up-close checking to see if I could spot any inconsistencies. Whether you do this is a 2D wireframe visual style or another is entirely up to you.

 

The only other thing that comes to mind is that the problem is entirely "visual" and is a result of an anomaly having to do with your graphics card.

That was my thought as well.

Looks fine here, just like image 1.

Ah, ok. Then it is something with my graphics. Thanks for your effort. Is there any graphic preferences I should look at?

Is hardware acceleration enabled or disabled? No matter which, try the opposite. What happens?

I tried to disable hardware acceleration and I also installed the latest graphics driver but it still looks the same.

Something's amiss:

 

Command: _solidedit

Solids editing automatic checking: SOLIDCHECK=1

Enter a solids editing option [Face/Edge/Body/Undo/eXit] : _body

Enter a body editing option

[imprint/seParate solids/Shell/cLean/Check/Undo/eXit] : _check

Select a 3D solid: This object is not a valid ShapeManager solid.

What is a ShapeManager solid? Does it have anything to do with Inventor itself?

SEANT, I created a standard box primitive and used the same command as you and I also get "This object is not a valid ShapeManager solid." So it seems that that message is showing up for all solids even if there is no wrong with them.

I believe the problem is being caused by whatever the object is supposed to be that I have circled in red in the above image.

 

Strange that I cannot visualize the underlying geometry in a 2Dwireframe visual style and that the problem only "appears" in a Conceptual visual style and not in the Realistic visual style.

 

I'm using AutoCAD 2012 at the moment.

Top view. Close up of one end.

I have circled the area where I think the problem originates.

What the heck is that piece of geometry I have pointed to? It is paper thin at one end. It also does not show up very well unless your view of the object is very specific.

 

Addendum: I finally did manage to "see" the offending geometry in a 2dwireframe but it is very easy to overlook.

That does not appear in the drawing here. The image I posted above was conceptual. :?

 

Weird.

If you look closely enough you can spot it even in conceptual visual style. I did not notice it immediately either.
