New web based sales-tool : design a stand in 3D - opinions needed

We're a small software company in Scotland launching a 3D web application into the wind, and need some opinions from the people that really matter.
(Until now, this has been aimed at banner Manufacturers)

It's for dummies ( present company excepted - of course! ) to just jump in and use without any training.

We're building a larger set of 3D product models, and constantly adding new features, so we need
opinions to help us focus on the most useful tools.

All comments, opinions, feedback are valuable and will be greatly appreciated. Hopefully we can have an open discussion that will help direct future development of this software.
