dumfatnhappy Posted August 29, 2008 Share Posted August 29, 2008 I'm trying to lay down railroad track and thought the sweep command is the best (only) way to achieve this. What controls the way it sweeps? see pic thanks Quote Link to comment Share on other sites More sharing options...
Strix Posted August 31, 2008 Share Posted August 31, 2008 are SWEEP and EXTRUDE different commands? Quote Link to comment Share on other sites More sharing options...
DavidB Posted August 31, 2008 Share Posted August 31, 2008 correct me if i am wrong but isn't SWEEP able to do it along a path? Quote Link to comment Share on other sites More sharing options...
Strix Posted August 31, 2008 Share Posted August 31, 2008 apparently EXTRUDE also has a path option (or am I wrong? I've not got AutoCAD to check on) Quote Link to comment Share on other sites More sharing options...
dumfatnhappy Posted August 31, 2008 Author Share Posted August 31, 2008 apparently EXTRUDE also has a path option (or am I wrong? I've not got AutoCAD to check on) strix you rock! I extruded it along a path. outstanding. many thanks! Quote Link to comment Share on other sites More sharing options...
Strix Posted September 1, 2008 Share Posted September 1, 2008 so now tell me the difference between the two coz I don't know and don't have AutoCAD to play with! Quote Link to comment Share on other sites More sharing options...
dumfatnhappy Posted September 1, 2008 Author Share Posted September 1, 2008 not sure really, all I know is the sweep went goofy and the extrude (along a path) worked like a charm. Like I said.... I'm just learning this solids thing. thank you Strix Quote Link to comment Share on other sites More sharing options...

Cad64 Posted September 2, 2008 Share Posted September 2, 2008 Revsurf will create a complex surface model made up of many facets. The SURFTAB1 and SURFTAB2 system variables control the number of divisions in the final mesh. Revolve will create a solid object. Quote Link to comment Share on other sites More sharing options...
dumfatnhappy Posted September 2, 2008 Author Share Posted September 2, 2008 ahhhh..... may have just solved my problem. Can you think of a reason *not* to make something a solid? me (I'm all about getting face(ed) Quote Link to comment Share on other sites More sharing options...
Strix Posted September 2, 2008 Share Posted September 2, 2008 ok, here is one for you...what's the difference between the revsurf command and revolve? One's solid and one's a mesh? edit: Note to self: read whole thread before posting! Quote Link to comment Share on other sites More sharing options...

dumfatnhappy Posted September 2, 2008 Author Share Posted September 2, 2008 if you're designing vacuum formed plastic? ok...now you're outside my environment..and I'll have to trust you :wink: Quote Link to comment Share on other sites More sharing options...
skipsophrenic Posted September 2, 2008 Share Posted September 2, 2008 if you're designing vacuum formed plastic? but once it's formed isn't that plastic a *SOLID* oblect? Quote Link to comment Share on other sites More sharing options...
Strix Posted September 6, 2008 Share Posted September 6, 2008 Nooop, it's a hollow object Quote Link to comment Share on other sites More sharing options...
skipsophrenic Posted September 9, 2008 Share Posted September 9, 2008 Nooop, it's a hollow object sorry brainmelt happened that day i thought it was solid. (The plastic i mean, not me brain - that's just cotton wool! ) Quote Link to comment Share on other sites More sharing options...
Strix Posted September 10, 2008 Share Posted September 10, 2008 vac forming is how they make those plastic trays microwave meals come in - amongst other things Quote Link to comment Share on other sites More sharing options...
