We switched from ETank to ITS Design some time ago and have been happy with the program and the support. ITS has automatic frequent internet updates and new features are added regularly. Also has AWWA design.
You might investigate iMap for Inventor technology preview at http://labs.autodesk.com and see if this provides the functionality you are looking for. I have not used so cannot verify.
I was anticipating problems based on our previous conversation. I installed normally. The only problem I had initially was recognizing the key and hasp driver. Once I used a USB port on the PC instead of the monitor everything seemed to install correctly. I did not have to use any compatibility...
We are experimenting with Vista 64 bit for our MCAD program. My understanding is that Vista 64 is not officially supported by Codeware. I was curious to see if anyone else was using Vista64 and what their Compress experience was.
So far it seems to work except for the cover page graphic. Have...

One of the easiest ways to center a rectangle about the origin is to draw a diagonal construction line from corner to corner and then use a coincident constraint from the midpoint of the construction line to the origin.
You may want to search the Inventor forum on Autodesk for this topic. Also you might want to look at a a trial version of AutoPOL or SPI- sheetmetal add-in for Inventor.
You mentioned you also had SW, you might look at Logopress3 for unfolding double curved surfaces

Also possibly exporting from Inventor into a trial version of Rhino and trying the "smash" command, although may not be accurate enough.

It has been awhile, but I think we have had occasional similar errors thru the years saving to our linux file server where the acad file lock did not release properly.
If it only affects one drawing you might try to "SAVE AS" and slightly change the file name, i.e. add a -1 to the filename. If...
ITS Design has been updated to Add 4 for sometime. We also have ETank which has not been updated yet. None of the API programs are as complete as Compress and may only have 1 programmer working part time on them.
