ReMark Posted September 1, 2011 Share Posted September 1, 2011 Revolved a plain old single line arc in my test. When I helped someone yesterday with a similar question (re: dome) I revolved a closed polyline profile thus ending up with a solid as one would expect.

JD Mather Posted September 1, 2011 Share Posted September 1, 2011 It might be the difference between the two releases, but in JD's example a surface was created, he forgot to mention that during the revolve command there is a MOde option to choose between surface and solid. Revolve of an open arc will result in surface body. Since 2007. See the 2007 tutorials in my signature. Quote Link to comment Share on other sites More sharing options...
Nishant Agarwal Posted September 1, 2011 Author Share Posted September 1, 2011 Might be an issue with the edition of autocad. I am stuck in 2008, and when i use the revolve command on my arc, it gives me a solid, not a surface. Seems that i figured this out the problem was that it is by default in solid mode so here are the steps > do not select the object...any object > initiate revolve command > then look at command line it says for SOLID or SURFACE > select surface SU > now a surface will be created > and then soild by thicken command thanks to all!!

rkent Posted September 1, 2011 Share Posted September 1, 2011 Revolve of an open arc will result in surface body. Since 2007.See the 2007 tutorials in my signature. Not if MOde is set to solid, in 2012 at least. Quote Link to comment Share on other sites More sharing options...
JD Mather Posted September 1, 2011 Share Posted September 1, 2011 Not if MOde is set to solid, in 2012 at least. Yes, I see that now. Kind of interesting that it automatically closes the loop, I exected the behavior to automatically change to SU if profile was open. I don't use AutoCAD much anymore. As Noted Shell will work with the solid hemisphere or change to surface output and thicken. Never would have figured this end in a 3-page thread.

pluissand Posted September 1, 2011 Share Posted September 1, 2011 In AutoCAD at the command line: 1-_sphere (press enter) 2-Specify center point or [3P/2P/Ttr]: 0,0,0 [the key to success in seconds] then press enter 3-Specify radius or [Diameter]: 100 4-_slice (press enter) 5-Select objects to slice: [You must select the sphere then you can read the AutoCAD message] :1 found (press enter) 6-Specify start point of slicing plane or [planar Object/Surface/Zaxis/View/XY/YZ/ZX/3points] : xy (near to the end....!!!) 7-Specify a point on the XY-plane :The sphere's center (please press Enter). 8-Specify a point on desired side or [keep Both sides] : (here press Enter, AutoCAD divide the sphere in two equal parts by the middle, to save time you keep with them). 9-Erase (you can erase later one of the sphere side if you want it) Quote Link to comment Share on other sites More sharing options...
