BenG Posted July 1, 2021 Share Posted July 1, 2021 I am designing a yard tool. I want to twist a cylindrical sleeve and have a pin travel in a spiral cutout to extend the interior cylinder. I can find no way to draw this. I can draw a partial spiral, but I have found no way to use Extrude Along Path to form a spiral cutout pattern to be subtracted from the cylinder.

Pat Stanford Posted July 1, 2021 Share Posted July 1, 2021 Something like this? Red Spiral was made with the Sweep tool and then Subtract Solids from the Blue Cylinder. To make an open spiral, put a locus point to the left of the circle at the point where you want the center of the spiral to be and select both then Sweep. Quote Link to comment
BenG Posted July 10, 2021 Author Share Posted July 10, 2021 Pat, Looks like you are on to somethig, but I am having a hard time getting it to work. I can't get a spiral to work. I make the blue and red circles. Put a 3D locus point in the center of the blue circle. Select the locus point and the red circle and then Sweep. Will not sweep - error message. Bottom line is I have been unable to make the red spiral. 2D locus doesn’t work either. With no locus points I get donuts. So, I need a little more instruction. Also, I need the spiral to have a square profile - to make a slot for a pin to ride in. Quote Link to comment
Pat Stanford Posted July 10, 2021 Share Posted July 10, 2021 The sweep requires a 2D locus at the center of rotation and it has to be to the left of the object to be swept. Make the swept object a square (or probably a rounded rectangle with equal sides and a very small radius on the corners [if you need this to be completely accurate]) and you should get a "square" spiral. What version of VW are you running? Quote Link to comment
