Arvid93 Posted January 4, 2012 Posted January 4, 2012 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? Quote
ReMark Posted January 4, 2012 Posted January 4, 2012 I'd double check the geometry first. Maybe you have a "snippet" of something left over from some editing you did. Quote
Arvid93 Posted January 4, 2012 Author Posted January 4, 2012 I may have missunderstood you but when I exported it to Inventor the part consisted of 1 solid because I used union to make all parts to 1 solid. The only editing I did after that was adding the fillets, which you can see here http://www.youtube.com/watch?v=25aDcid_j_o&feature=youtu.be Quote
ReMark Posted January 4, 2012 Posted January 4, 2012 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. Quote
Arvid93 Posted January 4, 2012 Author Posted January 4, 2012 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). Quote
ReMark Posted January 4, 2012 Posted January 4, 2012 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. Quote
SLW210 Posted January 4, 2012 Posted January 4, 2012 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. Quote
Arvid93 Posted January 4, 2012 Author Posted January 4, 2012 Here is the DWG. MultiToolBody.dwg Quote
Arvid93 Posted January 4, 2012 Author Posted January 4, 2012 Ah, ok. Then it is something with my graphics. Thanks for your effort. Is there any graphic preferences I should look at? Quote
ReMark Posted January 4, 2012 Posted January 4, 2012 Is hardware acceleration enabled or disabled? No matter which, try the opposite. What happens? Quote
Arvid93 Posted January 5, 2012 Author Posted January 5, 2012 I tried to disable hardware acceleration and I also installed the latest graphics driver but it still looks the same. Quote
SEANT Posted January 5, 2012 Posted January 5, 2012 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. Quote
ReMark Posted January 5, 2012 Posted January 5, 2012 What is a ShapeManager solid? Does it have anything to do with Inventor itself? Quote
Arvid93 Posted January 5, 2012 Author Posted January 5, 2012 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. Quote
ReMark Posted January 5, 2012 Posted January 5, 2012 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. Quote
ReMark Posted January 5, 2012 Posted January 5, 2012 (edited) 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. Edited January 5, 2012 by ReMark Quote
SLW210 Posted January 5, 2012 Posted January 5, 2012 That does not appear in the drawing here. The image I posted above was conceptual. Weird. Quote
ReMark Posted January 5, 2012 Posted January 5, 2012 (edited) If you look closely enough you can spot it even in conceptual visual style. I did not notice it immediately either. Edited January 6, 2012 by ReMark Quote
