I freely admit my ignorance if called for, but I am having a hard time envisioning a workflow that necessitates this feature.
Having a continuous display of where the mouse is on a given sketch plane is fine and can be helpful but entering direct coordinates to create sketch gometry can be an outright dangerous design practice!
Please explain in a littel more detail why you would need it and the workflow associated with it. The only workflow I can imagine at the moment is if you have a CNC program that provides you with coordinates and not dimensioned geometric elements and you want to recteate the geometry in 3D. Is that what you need it for ?
The reason why I dont "like" this feature is because about 5 years ago I worked for a company and the tooling that was designed and about to go into manufacturing was part of the companies prestiege project that was over budget already. In the middle of the project the lead design engineer left for another job and I was asked whether I could help with the tooling design, something I had not done in over 10 years.
The first look at the design in SolidWorks revealed to my utter surprise that non of the sketches that were used had any dimensions or any constraints. All of the tooling components were sketched by using the two little boxes that allow to enter coordinates! The enineer that then producced the drawings recognized this as well but instead of working with the other engineer simply applied all the dimesinoning directly in the drawings completely bypassing the parametric design intent.
It turned out that design changes were necessary and as the original design intend was not clear I had the manufacturerer send me the drawing PDFs and I had to completely re-design the toooing in order to apply the changes (fortunately they had not started cutting metal).
I can imagine that at least some of the requests or this feature come from a misunderstanding of how to properly create sketches in parametric modeling software.
BTW, I find Geomagic Design a very fine design package that given it's abilities is in no way to expensive.
I own a license and the only thing I don't like is that I have to fire up the VM on my iMac to run it.
Granted, F360 picing is very attractive even if you are not an early adopter.
