Custom footprint... cant get it right.

[Dalmation]

Hi,

I have been trying to make a custom component from scratch for this led display. It seems simple enough... take a dip10 and increase the width (space between pin rows) to 10.7mm.

I cant seem to get the precision I need with the rulers, htey seem to have a poor resolution (jumping 1mm at a time??).

Could I be really cheeky and ask if one of the more seasoned members could make it for me? Or if I'm doing something daft- it'd be better to learn, right?

Give a man a fish or teach a man to catch fish etc etc...  🙂

Either way- this is killing me.

Thanks once again, PCB Gurus!!

Dalmation,

To increase the resolution, go to Options >> PCB Properties, select the Grid & Units tab. Now, change all the following to 1 mil or to whatever minimum resolution you need:

Visible Grid, change the numeric field to the right.

Grid Step Name list, select Component Grid, change the Grid Step Value.

Grid Step Name list, select Copper Grid, change the Grid Step Value.

Grid Step Name list, select Via Grid, change the Grid Step Value.

Grid Step Name list, select SMD Grid, change the Grid Step Value.

Click Apply and OK to exit. You should now see a finer grid.

Thanks for that- that actually solves another problem I've had as well.

Once again- really appreciated.

Excellent!

However- is there any way to increase the accuracy of the ruler bars? They are still oonly giving me a resolution of 1mm.

I can move between the 1mm graduations, but I'm still having to guess a little.

Thanks.

I see what you are saying... I set it up as 0.1 mm resolution and I can gradually move the ruler on that resolution, however the display will only show digits 1 mm, and then 2 mm but not the intermediate precision like 1.1, 1.2, etc...

I check and apparently that display is not prepared to show digits of precision, I will make a note for R&D about this. In the meantime if you really want to see intermediate numbers on the display try switching to um instead of mm. However I would recommend to stick to mm to avoid any misinterpretation of data.
