Hi,

we are planning to make mechanics for architecture and product visualisations. To create what is really demanded/requested, we would like to get input from professionals what they could need/require for their different use-cases.
Here are some groups of features we have as basis to start with, please add youre requests/wishes in the postings below or contact me via PM directly.
