>There's always the pressure to convert to Inventor. I've looked at the Inventor newsgroup and there are some unhappy campers with Inventor.
Why don't you post this question over there?
That is where the people who have succumbed to the pressure to convert hang out. You might get some input from their experience in making the transition, here you are limited to those who couldn't make the transition. I used to tell my class first day that MDT was my preferred CAD program until I fully understood Inventor.
Inventor Plus
No need to profile sketches
Shared sketches
Derived sketches
Derived parts
Far easier parametric work-plane creation (I ran into a lot of MDT users who use ACAD UCS command to create non-parametric sketchplanes/workplanes).
Parametric surface creation
Sculpt tool that doesn't exist in MDT
Boundary Patch tool that doesn't exist in MDT (tangent)
Loft options that don't exist in MDT
Sweep options that don't exist in MDT
Fillet options that don't exist in MDT
Interactive assembly constraints that don't exist in MDT (I ran into a lot of people who use ACAD align command instead of parametric 3D constraints which they didn't understand how to use).
Assembly motions that don't exist in MDT
Sheet metal flat pattern generation with bend allowance
Construction Environment tools for fixing imported geometry (MDT used to lead in this function - no longer true).
Frame generator tools that don't exist in MDT
Inventor Studio
DWF Animation
Assembly save as stl
Creating traditional 2D drawings from 3D models or assemblies is far easier all the way around.
I don't understand what all the difficulty is that long time MDT users have with part, assembly and drawing files being separate files. What is the difference between a file and a folder in terms of management? In the digital world a file or a folder of files is all 1s and 0s. Actually in the physical world a part is a part, an assembly is a group of parts, a drawing is a flat sheet of paper, not a part or an assembly. Wow that is confusing to keep track of. (I often saw MDT users always start with an assembly file rather than a part file and they didn't know how to use the assembly Catalog).
>I can build solids with MDT. So, why would one change over?
That is great! Your CAD software purchases are over as MDT is no longer sold anyhow. Be happy you don't have to keep up with learning all of the above and the inevitable pains with new technology. Just hope your employment is secure clear to retirement. (Same thing I said to board drafters 20 years ago.)
