MarvinX Posted August 3, 2009 Share Posted August 3, 2009 Hello to you all, first post althought i've been using Autocad many years. For my latest project i am trying to create a solid with the loft command and i can't figure out what i am doing wrong... Any help appriciated. Thanx Dirt.dwg Quote Link to comment Share on other sites More sharing options...

MarvinX Posted August 4, 2009 Author Share Posted August 4, 2009 Thank you JD. i can understand your method but when i try to create the slicing surface (two lines for cross-sections and the 2dpolylines for guides-even the one of them as path) I keep getting... "Modeling Operation Error: The guide is not G1 between first and last sections. The selected entities are not valid." And the thing is that loft as a command should do this things in a snap...Been used to maxs' loft command wich is a thousand times better! Can't compare different things but i have to express my coplains Quote Link to comment Share on other sites More sharing options...
JD Mather Posted August 4, 2009 Share Posted August 4, 2009 And the thing is that loft as a command should do this things in a snap... Speaking of snap. One of your profile curves did not meet the guide curve (no osnap) so I moved it. Use the multi-entity polyline as the profile curves and straight lines as the guide curves (actually don't really need - but I use anyhow).

SEANT Posted August 4, 2009 Share Posted August 4, 2009 ...Been used to maxs' loft command wich is a thousand times better! Max does not have a very demanding geometric tolerance. If the three curved poly’s are to be used as guides, they should be re-filleted to ensure tangency (G1 continuity) at the vertex. Quote Link to comment Share on other sites More sharing options...

That's why i said "you can't compare diffent things,but..." :wink: I managed to create the solid by cutting the procedure in three steps (the three different colors at the attached). This meant that i had to draw 2 more cross-sections(in white color in the attached). The thing is that i could not do it in one step wich i believe is possible and has to do with the G1 continuity as Seant mention! I'll work it out a bit and see what will come up. Thank you all for your time. Dirt2.dwg Quote Link to comment Share on other sites More sharing options...
