Hello,
I have question regarding the practice of mixing ordinate dimensions with standard linear dimensions.
Geometric Background:
I have a rectangular plate with a short edge slot defining the center-line of the plate in long direction. Also the plate has four shallow and narrow pockets running parallel to the slot, symmetrically positioned about the centerline.
DATUM A (PRIMARY) - Large Flat Surface of Plate
DATUM B (SECONDARY) - Edge Slot Width Centerline
Datum C (TRESHERY) - Top Edge of plate
So, I would like to the control the position of one edge of the shallow slots relative to DATUM B as well as the slot width. This is for accurate mounting of four linear slides.
Question: Is it okay to use ordinate dimensions to locate the slot edges and standard dimensions to specify the shallow pocket width?
More generally, is it okay to mix ordinate and standard dimension on the same view and sheet?
Thanks,
Dion
