br0604bom Posted October 31, 2010 Posted October 31, 2010 (edited) I have tried out the shell command and removed the top surface of an extruded rectangle and it seems to work fine. Then I copied and pasted my 2d line drawing into the 3d drawing, and now when I draw round the building core and attempt to shell it and remove the top surface so I can see in from above, it is not doing it, the top stays filled and nothing happens, could it be that copying the 2d line drawing in is corrupting the shell coommand in some way? The thing is, I need the 2d line drawing in the 3d drawing!! Thanks very much if someone can help me Edited October 31, 2010 by br0604bom Quote
br0604bom Posted October 31, 2010 Author Posted October 31, 2010 I hope this shows up ok, it shows that the shell command does not seem to work on solids of a certain size, as it has only worked on small solids, is this correct? and if so, can you change a setting somewhere to allow it to sheel larger solids? the three small solids are shelled 100mm, and the white lines on the end of the large solid show how far in it would be if it was shelled 200mm. does anyone have similar problems with the shell command?

ReMark Posted October 31, 2010 Posted October 31, 2010 Is this the error message you are seeing when you attempt to SHELL large objects? Modeling Operation Error: No solution for a vertex. In a little experiment that did NOT include the insertion of 2D linework I did hit a point at which the SHELL command failed to work as anticipated. I have yet to find any "setting" or variable to adjust for this strange behavior. Quote
JD Mather Posted October 31, 2010 Posted October 31, 2010 [/i] I have yet to find any "setting" or variable to adjust for this strange behavior. Not really "strange" behavior. Common to virtually all CAD programs. There is an upper limit to upper/lower boundry box (this includes distance from origin) related to floating point math calculations. A Google search should turn up some technical descriptions of the problem. Quote

There was no message like the one you mention, this is what happened after I did it, it just gave a list to edit further, this is a basic solid alongside the cad plan with core i want to shell, obviously this solid is bigger than the core but it was for testing purposes, and it will not shell thanks JD, sort of explains a bit on why it is not working, so will moving the large solid close to 0,0,0 make it more likely to work?

JD Mather Posted November 1, 2010 Posted November 1, 2010 On something the size yours appears to be you should not be seeing the behavior I describe unless it is a long ways from the origin and/or not to the scale I would expect. Quote

br0604bom Posted November 1, 2010 Author Posted November 1, 2010 (edited) Attach the file here. wt_10.dwg never put a dwg on here before,hopefully this will work! can you open this ok JD? did you manage to open this JD? Edited November 5, 2010 by br0604bom Quote
