Kevin McAllister Posted April 9, 2019 Share Posted April 9, 2019 I'd be curious to know myself. For years arcs behaved the same as your second example. A few versions ago it changed and now arcs extrude to wedge shaped solids. I've often wondered why they revert to a wireframe surface when the fill is set to none. Its like they partly maintained their old behaviour. @Jim Wilson do you know why this is? Kevin 1 Quote Link to comment
Andy Broomell Posted April 11, 2019 Share Posted April 11, 2019 I loathe the fact that arcs extrude into a wedge shape. It's inconsistent with how other non-closed shapes extrude. 3 Quote Link to comment
zoomer Posted April 11, 2019 Share Posted April 11, 2019 While I would rigorously forbid any kind of "Fill" appearance for any non-closed Objects anyway ... 1 Quote Link to comment
halfcoupler Posted April 12, 2019 Author Share Posted April 12, 2019 ok, the rule seems to be that there are 2 differend types of extrudes, (please correct me if I'm wrong): - 1) Extrudes based on non closed 2D-polylines, which apper as "shell-extrusion" - 2) Extrudes with other (vector-) mathematical definition like circle, oval, rectangle, closed polygons and arc, which appear as "solid-extrusion" The only way to get the "shell-extrusion" from the second type is to convert it to non closed 2D-polygons before extruding Extract tool is no option for getting extrudes, since it results in a nurbs surface, not in an extrude.
