Increasing radius pattern.

Increasing radius pattern.

Increasing radius pattern.

(OP)
Lets say you were making a block to hold gauge pins.  How would you drive 250 extrude cuts with an increasing diameter. They do not have to be equally spaced.

I have been trying in a sketch to drive it every which way but I just cant get it to work.

Josh

p.s. I can make it happen in NX4, but not in solidworks.

RE: Increasing radius pattern.

Can you use a Spiral curve for a radial pattern?  Check out Curve-Driven Patterns in Help.

But I want each extrusion to be .001 bigger than the last.

RE: Increasing radius pattern.

Oh, now I know what you mean--I'll have to think about that.  Maybe with a Design Table?

Sounds like a job for a drawing macro with user inputs for start diameter, size increment, pitch, direction and number of iterations.

cheers

RE: Increasing radius pattern.

I'd suggest a macro.  I'm not really familiar with the SolidWorks API, it'd be easier for me in AutoCAD.  I'd record a macro of sketching a circle, examine the code, then set up some sort of recursion to get your pattern.

RE: Increasing radius pattern.

How do you do it in UG?

Jason

UG NX2.02.2 on Win2000 SP3
UG NX4.01.0 on Win2000 SP3
SolidWorks 2007 SP2.2 on WinXP SP2

I would create an instance, and then drive that instance via expression.
