Need help drawing Circular array of holes

[Complete_Loser]

This is giving me brain hurts.

When i do the circular array i cant get the 31deg right.

Any help is appreciated.

What program are you using to draw it?

Pcam 3.11

I have Design Edge and not 3.11. What does your array tool window look like? Here is the array tool in Design Edge.

Holy cow, lol mine looks nothing like that.

How much $ you want for the file?

Yours should work the same way. I will show you how to do it. Stay tuned.

Let me know if you have any questions about the process I have shown below. I suspect you will gain more satisfaction from learning how to do it yourself than having me do it for you. Once you see how to do it, I'm sure it will come in handy in the future for other projects you might have.

Question: Doesn't using the single closed path at the 9:00 position to draw an array of six holes at 31 degrees, and another array of six holes at -31 degrees create TWO closed paths at the 9:00 position?

Apparently not.

Thanks for the help Adbuch! I needed this done, so i went ahead and drew it last night the hard way and cut it out. I will look at our write up and see if i can make it work also. Thanks again for the hard work!

Inkscape has a similar method for placing objects around a circle (good old Nick again) I wanted to make a sanding flap disc which had a way to attach sand paper around a disc with easy removal to replace the paper, This is the cut plan I used, routed from plywood.

Apparently not.

Yep. You're right! The double path occurs when you mirror a group from left to right, using the center of the original circle as the ortho anchor point. I've never done an array LEFT-RIGHT like that. Too many keystrokes.

When you figure in your additional rotation, the difference in keystrokes, mouse clicks, data entry is minimal. Maybe 2 or 3 at the most. But your method is good, and can save a few seconds from the process. Either method is much quicker than doing it the manual way by continually rotating a spoke and then placing all the holes with the copy command.

Tom - I tried it with Inkscape and it's pretty easy to do to get the array. The hard part is rotating it around (which I didn't do) to get the final rotational angle to match the drawing the OP provided. I checked it with Design Edge and the angles came out correct.

Here is a different method that may do as you want, I have not had any projects that need these so have not researched it.

Thanks Tom! I will check it out when I get a chance.
