Are there plans to add simple equations to the dimension dialog box, or to allow for cross unit dimensioning? I often model in mm but will include some parts in inches. In others software I simply add the unit behind the dimension and that is all that is required. Another feature I commonly utilize is simple equations in the dimensioning field like 2.3468/2 to get a radius.

I have been keeping my calculator docked on the right side for this for now but I’d love to see this functionality included in the software.

Thanks!

I’m waiting this feature for long time…it would very helpful when we do copy some objects (Array)
