trying to draw a line along the face of a cylinder

Postby sebastia » Tue Oct 01, 2019 7:47 pm

Hi! i am trying to draw a line along the face of a cylinder but i can't seem to get it to work. whenever i draw a line it goes through the cylinder instead of along the face. Any suggestions or help would be greatly appreciated.

Hi and welcome to the forum!

The information you gave is a bit sparse. It would help to know which workbench you use and your final goal would be interesting too.

HI, i orignally drew the cylinder in the parts workbench. the end result is suppose to be a cylinder with a row of knives attached to the outside of the cylinder at an angle. imagine a 55 gallon drum with knives poking out in a diagonal pattern across the surface of the drum.

Hello
I suppose as you need to do a sorte of malaxer for concret, whith a helicoidal plate of metal around the internal surface of the drum
In this case do it whith a addpipe along an helix by path

This is one of those situations where I do some things outside of Part Design. I made the helix in Part and the array in Draft. I made the pad sketch a bit smaller than the helix so the lines are easier to see.
