What are considering switching from to ViewDraw? Time has not been
kind to that old-lady. The underlying database design is very old.
Most enhancements are in the form of slow, and clumsy add-ons that
communicate through VB automation, DxDatabook, DxDataManager, Variant
Mgr, etc. They are now very married to the Redmond monster. Using VL
product is a lot like using the ancient VAX TPU edit engine. The
database is exposed as both ASCII files, and through the automation
links, but the tool as provided is so lacking that it is up to the user
to create basic functions like title block and hierarchy management.
VL has spent the last couple of years "NTifying" their once capable
PowerView product, and largely annoying the NT Workview user base with
"creative feature enhancements", which usually consist of figuring out
which existing feature they will clobber or outright remove. A big clue
about the state of VL is their stated policy, 12/99, that they do not
officially support any products on NT4 sp4, sp5, or sp6. The most
release they officially support is the long-dead sp3. Yes, it is rather
incredible but true.
There have been no single digit point releases to ViewDraw in almost two
years. The three .0x bug-fix releases have each been a very mixed bag.
We have some users who actively oppose using anything newer than the
release due to the useability problems those "creative feature
enhancements" have introduced.
I am curious how the Cadence and Mentor customers feel about their
respective tools, and suppliers.
