I am trying to make an interactive website (like www.3dtuning.com) using CAD models from the engineering team (.stl ) with Blend4web PLugin. But the output file size (html) was too big (1.2GB!) so that the browser didn't display it. Then I reduced the size to 500 MB using Meshlab. The output now opens in a browser but small parts of the models are missing and 500 MB is still too big for a webpage.
Some people I spoke to say that I should model in Blender on top of the CAD models, use the Blender Models and discard the original CAD Models. This seems redundant because I am remodeling after the engineering team has already modeled it once.
Is this a normal procedure for making such websites?
I have already read other similar questions on the site, but they don't seem to have the answer.
