DIJONAISE  I have been using Strata 3D for about 4 or 5 years and this update (5.5) breaks a lot of functions.

Tons of behaviors have been changed for no discernible reason.

For example, new items get stuck to the ground plane unless a newly checked box is unchecked. Field of view moves in the OPPOSITE direction it used to, etc.

Tech guy tried to humiliate me for asking about changes to the program behavior.

It is a shame because I USED to like these guys...

DIJONAISE  For years now extensis has been selling crappy vaporware and I, for one, am sick of it!

Here is how they operate:

Step 1: Make a lot of grand sounding promises.

Step 2: deliver about 80% of what the customer pays for.

Step 3: Wait 6 months, roll out the promised vaporware and charge a full upgrade for the code already sold to the customer in step 1.

Step 4: Deliver product that doesn't even really work.

Case in point: We are on our fourth generation of the Portfolio Family of products and the main feature that I sold this crap to my bosses with, (cross platform asset server) still, to this day, does not work!

These people will burn you too!

My professional recommendation is to avoid all extensis products as they are primarily a marketing/profit driven company that will not provide a stable, functioning product. Furthermore the products they sell you will be deficient, and when they do get around to delivering the promised features, they will force you to pay more money for what you already bought.
