spinecad Posted March 3, 2013 Share Posted March 3, 2013 Is it possible to convert surface into solid in AutoCAD 2002? For example, can I convert these five surfaces into a solid pyramid? If yes, what is the step to do it? Quote Link to comment Share on other sites More sharing options...
ReMark Posted March 3, 2013 Share Posted March 3, 2013 (edited) No surface to solid capability in 2002. Edited March 4, 2013 by ReMark Quote Link to comment Share on other sites More sharing options...
JD Mather Posted March 4, 2013 Share Posted March 4, 2013 You could extrude that base directly using path (3 times) and solidedit intersection to finish. Quote Link to comment Share on other sites More sharing options...

ReMark Posted March 4, 2013 Share Posted March 4, 2013 (edited) If the end result is a pyramid shaped 3D solid what does it matter? Edited March 4, 2013 by ReMark Quote Link to comment Share on other sites More sharing options...
JD Mather Posted March 4, 2013 Share Posted March 4, 2013 Yes I know. But that not an answer. How is it not an answer? OK, here is a more precise answer to your precise question. You will need a later version of AutoCAD to convert surfaces to solids. Quote Link to comment Share on other sites More sharing options...
f700es Posted March 4, 2013 Share Posted March 4, 2013 Wasn't there a Pyramid command in r2002? Quote Link to comment Share on other sites More sharing options...
ReMark Posted March 4, 2013 Share Posted March 4, 2013 If you are speaking about Primitives I know that AutoCAD 2000 came with six: box, sphere, cylinder, cone, wedge and torus. Not sure if pyramid was added in the jump to 2002. Just checked and Bob McFarlane's book Modelling with AutoCAD 2002 mentions the same six primitives.

f700es Posted March 4, 2013 Share Posted March 4, 2013 Yeah, I am not sure either as I don't have a copy installed to check. It might not have been. Quote Link to comment Share on other sites More sharing options...

JD Mather Posted March 4, 2013 Share Posted March 4, 2013 Wasn't there a Pyramid command in r2002? If there had been, I would not have had to figure out the trick I posted above. Of course now I would use the Loft to point. One could use the Extrude with Taper, but this only works with special cases and requires calculations (which I try to avoid when I can solve with geometry). As I recall, the 3 extrude with path and intersect trick works for general cases, even where the apex is offset. (but then my recall is getting fuzzy) Quote Link to comment Share on other sites More sharing options...
f700es Posted March 4, 2013 Share Posted March 4, 2013 I couldn't remember when it was introduced (let's use fuzzy recall as well). Quote Link to comment Share on other sites More sharing options...
ReMark Posted March 4, 2013 Share Posted March 4, 2013 If the OP has Mech 2012 why go through the bother of trying to use 2002? Quote Link to comment Share on other sites More sharing options...
f700es Posted March 4, 2013 Share Posted March 4, 2013 Torture? Maybe trying to help someone else out with an older copy? Quote Link to comment Share on other sites More sharing options...
ReMark Posted March 4, 2013 Share Posted March 4, 2013 If he wants to torture himself I can show him how to do it using a primitive wedge solid and the SLICE command. It will take about six steps. The only surfaces involved would be used to slice an object created from the union of two wedges. Quote Link to comment Share on other sites More sharing options...
JD Mather Posted March 4, 2013 Share Posted March 4, 2013 If he wants to torture himself.... I think I saw an earlier thread where he was comparing SolidWorks to AutoCAD (apples to oranges) when a more appropriate comparison would have been Autodesk Inventor. More information is needed on why the requirement to use surfaces. Quote Link to comment Share on other sites More sharing options...
SLW210 Posted March 4, 2013 Share Posted March 4, 2013 I believe his main purpose is to sell tutorials. If yes, what is the step to do it? So, the desired answer to the original post is a step-by-step tutorial on converting the surfaces into a solid. Quote Link to comment Share on other sites More sharing options...
f700es Posted March 4, 2013 Share Posted March 4, 2013 Show him how so he can "try" to profit of it........... I really hope that is not the case. Quote Link to comment Share on other sites More sharing options...
scj Posted March 4, 2013 Share Posted March 4, 2013 For converting a bunch of 3DFACES into 3DSOLIDS the F2S.lsp from Bill Gilliss is very helpfull - you can google for it. It works similar to the M2S.lsp I wrote a program for making Tetrahedrons by slicing (see attached TETRA.lsp) Regards Jochen tetra.lsp Quote Link to comment Share on other sites More sharing options...
ReMark Posted March 4, 2013 Share Posted March 4, 2013 The OP could always "upgrade" to AutoCAD 2007 and use the THICKEN command to convert a surface to a solid. Quote Link to comment Share on other sites More sharing options...
