this shape wont drape or extrude, why? VW17

Recommended Posts

neither command works on this shape

extrude fails to extrude polygon correctly, and ONLY extrudes sides (as opposed to extruding polygon plane)

drape doesn't work at all...

Furthermore, the shape I need would entail sloping down the spiral at the broader end... how would you do such a shape???

any suggestions?

I agree with Mark. Either the polygon is not closed or you have No Fill assigned to the object. What you get are the extrusion of the lines but not the extrusion of the "body"


Another way to do this would be to use the Polygon tool in Eyedropper mode to create a new object the shape of the object and extrude that

If the polyline isn't completely closed, a quick way to fix this is to select the shape then checkmark the "Closed" box in the OIP. Then you should be able to Extrude it properly.

Possibly what you are after??


Created an extruded rectangle, used knife to cut the taper then used the deform tool to bend it around. AAdded solid for blob in centre.
