I am trying to create a Non car part but can be most resembled as a Perforated Velocity Stack...with the hole being large. Kinda like a Swiss cheese velocity stack. anyone have any helpful info or Drawings they could help me with to get started?

 

So...is it a flat piece that is perforated like swiss chesse, or is the tube of the velocity stack have holes throughout?

its the velocity stack with large holes starting after the shoulder: heres a quick example.



with the holes being i gues a 1/2" spread out after the shoudler

 

Does it have to be done in autocad? If so what version of autocad are you using?

 

no i dont i need help with it...useing 09

 

Create the side view of the tube.
Sweep it.
Draw the circle size you want for the perforation. Extrude it. Place it where you want and then do a solid subtract. To get the perforated look, you are going to have to subtract a number of these extruded circles.

 

bumpage...been lazy and lost the thread when this forum switched to ****...

 

the method of drawing the side view and then revolving it is the easyest way to make it, and then just subtract the cylinders all around the solid. What are you making this for? home made jet?
