Dimensioning

Hi,

I want to choose the dimension i want to set rather than changing the random dimensions that appear. How do i do this? The part is a basic curved meccano strip so i want to set the holes 1/2'' apart from each other but it's giving me the distance to the center line to change which isn't useful at all.

Could you help me please understand how the dimensioning works!

Thanks

One idea, I'm not sure this is the best way though.

Excuse my ignorance but how did you get that? That is what i'm wanting, the curved distance between the centers of those 2 circles

Perimeter dimensions are created in sketches. You select the feature or features you want the perimeter value for and once you place the dimension, you need to select which dimension you wish to vary to meet the perimeter value.

If you are using hole features, you might make the sketch with datum points to use for locating the hole feature. Otherwise, you can simply extrude w/ remove material the holes directly where the sketch is a section instead.
