The Inventor software does not have the ability to do a foreshorten radii as illustrated in the ANSI dimensioning and tolerancing documentation (see ANSI illustration figure 1-23).
As shown the foreshortened dimensions doesn’t come close to the ANSI standards.
This idea has been brought up several times here but, never has been implemented. It would be nice to see this idea revisited and this basic function inserted into the Inventor software.
