To Many Lines & Dims in one sketch

Hello Everyone,

This is a new problem for me.

I have 100 cord lines & points to draw on a small diameter face ( .300 )

I have cord length & angle Dims for each one.

I was able to input all my data - but my screen is a mess.

Is there any way to put the Dims on layers so I can only bring up cords or only bring up angles....???

Second Question,  I learned to watch my auto snaps closely - then learned how to turn them off when I was not getting the cord Dim I wanted ( was getting vertical Dims ) instead.

But I can not seem to edit them after I find My mistake.    I wanted cord length & after I typed in the Dim box It ended up as a Delta Y  -   The only way it seems I can fix this is to delete it & do it over.

Is there a way to edit this with out the re-do....?

Thanks

Rich
