Gang....

this should be simple, but I'm having a hell of time with it.

making a new part, a rotary switch. The specifications are .700 diameter with the pins at 39 deg. There are nine pins
I wanted to make a circle .700 in diameter and then place the pads along the circumference. Easy!

Well not so much. I can make a circle, but it's far from round.

There's got to be a way!

Thanks,

mike

Have You tried to use the Pattern Utility?
- open Pattern Editor
- create new Pattern Item
- In Pattern Properties select Style "Circle"
- Enter the Number of Pins (I believe 9 Pins are 40°, not 39°)
- select Radios 0.35 Inch
Ready...
You can chnge the Padstyle to Surfacemount or Throughole after that

Using TurboCAD:
Draw a circle .7 diameter using Grid snap, 0,0
Switch snap to Quadrant and draw a circle the size needed for the pad at 12:00
Select the 'pad' Click Modify/Array/Fit Radial
Tab to inspector bar and make Sets = 9, Angle = 320 which will set +ROT at 40 (360/9=40) then Enter
You can delete the .7 circle and save as DXF
Import the DXF as Top Pad, select all pads right click properties and change to Through-Hole with whatever hole size needed.

The Snaps and Array stuff that TurboCAD (or other drawing programs) took TurboCAD years to work through and they keep expanding.

OR
In Pattern Editor create a new pattern by selecting Style=Circle, Pads 9, Radius .35
done.

In the time it took to figure out the DipTrace way @dipicorg posted!
DipTraces way takes a lot less time...
