Hi Shapenoid,

Have you try Spaceclaim? This software price tag is in different league of Moi, but i think they have a free trial fully working.
Those 40 could be done in 1 day - depending on each complexity - but Spaceclaim is very easy and fast, even when dealing with complex data.
Spacecalim is much more then a dimension tool but this aspect is very well developed.

Cheers

Carlos
