How to do this

Can you not make a DXF form your drawing and import to eagle?

OK you must perhaps set holes manuel.

I know how to make a round board but our enginering departement asked me

to produce a disk like the one in this drawing:

Could someone tell me how to do this?

 

Thanks

You only need to calculate ONE hole for this. Work at 3, 6, 9, or 12

o'clock. Lets say you're at 6:00... .

 

Draw the circular board outline with the origin as center. Draw your first

hole at 6:00.

Copy the hole and place the copy outside the circle, (use a coarse grid if

you can).

 

Group the board, rotate it by 7.5 degrees, then copy the hole copy back to

the 6:00 position.

 

Group the board, rotate...

 

(To rotate the PCB: group the entire PCB, click the move icon, RIGHT click

the group AT THE ORIGIN, type 7.5 in the angle box, ENTER, LEFT click the

ORIGIN. The board should have rotated 7.5 degrees. You might want to make

an index mark at some point on the board before you start, that's up to

you.

 

It would get more complicated if you had to do oddball angles, (maybe,

360/7?) but you could work with some multiple of the base angle -

depending on your allowable error.

 

Since the total number of holes is divisible by four, you can probably do

a group copy once you're 1/4 the way done, then once again for the second

half. Simply eyeball the placement. You will have extra board outlines on

top of the original that should be removed.

 

oww, dizzy -gottaa go

Take a look at the Download area, Misc folder.

There are two or three tools that allow to convert DXF into EAGLE

script format. Simply search for "dxf" with the search function

of your browser.

Bear in mind, though, that the DXF format is a very loose standard and

the import tools have limitations on which object types they cope with.

When I tried it on a logo design, the tools all achieved exactly the

same result - nothing.
