ILoveMadoka Posted March 25, 2009 Share Posted March 25, 2009 I've created a complex solid. I then created several sub objects to subtract ie: "punch holes" and such. I've been working on this model for several days without incident. All morning no problems. I shut down my autocad and this drawing. When I reopened the drawing all the subobjects used to modify the main object are now showing up as part of the model. It's like it has returned to a point in time in the History when the main shape was first being modified. Can I get the model back to "normal?" Is that understandable at all? TIA!!

ILoveMadoka Posted March 25, 2009 Author Share Posted March 25, 2009 (It's Autocad 2009 if it matters) In the help it states: For composite solids, set the Show History property to Yes to display wireframes of the original forms (in a dimmed state) of the original individual solids that make up the composite. Well these "History Objects" are not wireframe and changing SHOWHIST, SOLIDHIST or BREP has no effect on them at all. To hopefully clarify. The main object has returned to a state that it was several days ago. Just trying to figure this out!! Help! Help! Help! PLEASE Help! And thanks!

ReMark Posted March 25, 2009 Share Posted March 25, 2009 You're working off a network and managed to load an earlier version of your drawing. Could that be the cause of the problem? Quote Link to comment Share on other sites More sharing options...
ILoveMadoka Posted March 25, 2009 Author Share Posted March 25, 2009 No chance.. All the latest changes are there along with the historical objects.. Quote Link to comment Share on other sites More sharing options...
ILoveMadoka Posted March 25, 2009 Author Share Posted March 25, 2009 In it's simplest form. I created a cube. I created a cylinder in the center of the cube. I subtracted the cylinder from the cube creating a hole. Several days later the cylinder magically reappeared. The cube and the cylinder are one object. The Separate command will not break it apart. Man this is frustrating!! Quote Link to comment Share on other sites More sharing options...
ReMark Posted March 25, 2009 Share Posted March 25, 2009 No chance..All the latest changes are there along with the historical objects.. "The main object has returned to a state that it was several days ago." I'm at a loss to explain this seemingly contradictory state of affairs.

JD Mather Posted March 25, 2009 Share Posted March 25, 2009 I have seen this behavior since v2007. I can fix you model if you can zip and attach it here. Quote Link to comment Share on other sites More sharing options...
ILoveMadoka Posted March 25, 2009 Author Share Posted March 25, 2009 You can't tell me how to do it? Point me in a direction? Give me a command to research? I'm not stupid or a novice. All the 3D guys in the office are all scratching their heads over this one!! Quote Link to comment Share on other sites More sharing options...
ILoveMadoka Posted March 25, 2009 Author Share Posted March 25, 2009 There is absolutely NO CHANCE this is an old version! It's like building a house. You lay in your plumbing, set your footer and foundation forms, pour your concrete, start the carpentry. Now all the plumbing is magically gone or the forms have magically reappeared! All the geometry created AFTER the modifications in question IS ALL there. The "hole punching" as it were, was done last week. Many, many entities and elements have been created every day since. Objects have been created and placed in those "holes." They are still there. Everything I did this morning is still there. The objects that are normally deleted during a subtract are now all a part of the model. They were NEVER a part of the main object. Never. You can't subtract them if they are! But they are now!!

JD Mather Posted March 25, 2009 Share Posted March 25, 2009 Give me a command to research? solidhist brep Attached is the typical case I see. I moved the green desired part out and up a bit after repair. The cyan is the unexpected behavior. Quote Link to comment Share on other sites More sharing options...
ILoveMadoka Posted March 25, 2009 Author Share Posted March 25, 2009 >>solidhist >>brep As stated above neither of those had any effect on the dwg... Quote Link to comment Share on other sites More sharing options...
JD Mather Posted March 25, 2009 Share Posted March 25, 2009 Will not have effect on current work. Change for all future work if you don't want to see repeat behavior. Quote Link to comment Share on other sites More sharing options...
ILoveMadoka Posted March 25, 2009 Author Share Posted March 25, 2009 Recovery has no effect either. I have three drawings, all created from the one base drawing. 2 are fine. Only the one is demon possessed... Quote Link to comment Share on other sites More sharing options...

ILoveMadoka Posted March 25, 2009 Author Share Posted March 25, 2009 >Post it.. I wish I could. Confidentiality issues with the client. While I've given up and recreated the model from scratch there is one more notable observation. When the model is loading, it appears fine. It's not until the final dll's and such load and the screen regens that my mystery geometry appears. Does the same thing on other machines as well. Autocad 2009, Autocad Mechanical too... I'm going to run all the Autocad updates and see if that does anything... even with the tweaked settings didn't work either.> Thanks so much for all the input! I appreciate it!!

JD Mather Posted March 25, 2009 Share Posted March 25, 2009 When the model is loading, it appears fine. What do you mean it appears fine? The bitmap preview image is just that, a bitmap image captured at some point - not CAD geometry. This has fooled and frustrated many with corrupt files. even with the tweaked settings didn't work either.> Requires some in-depth knowledge of Inventor, but the fix is really simple when you know the trick. http://www.myvbooks.com/ac55jsp/stores/1/Autodesk_University_2008_Inven_P271C95.jsp?UserID=1321761&ACBSessionID=57B2258CFE2BC113DDE3 Quote Link to comment Share on other sites More sharing options...
Jimmy111 Posted June 27, 2013 Share Posted June 27, 2013 I seem to be having the same problem in autocad 2010. Just started happening. Certain drawings i made in one computer if they are coppied, all the subtracted subobjects show up and parts of a single solid. If I take the drawing and open it in another computer, the same thing happens. It seems to be drawing related. Any Ideas? Quote Link to comment Share on other sites More sharing options...
ReMark Posted June 27, 2013 Share Posted June 27, 2013 Post a copy of the drawing and someone here will take a look at it. Quote Link to comment Share on other sites More sharing options...
JD Mather Posted June 27, 2013 Share Posted June 27, 2013 ....Any Ideas? Did you read this thread? Quote Link to comment Share on other sites More sharing options...
Jimmy111 Posted June 27, 2013 Share Posted June 27, 2013 Yes of course. I read the thread. Solid history was on but it is always on and I never had this problem before. It is not big problem for me on this drawing but I have many others that if this does happen it could take weeks to redraw them. So I was wondering if anyone knows what causes this. Perhaps some toggle somewhere? The interesting thing is that it seems to have something to do with copying the drawing to clipboard or using the copy command.
