Not sure if this part of the forum is active or not but here goes.
We use keyshot with (mainly) SolidWorks 2016 and Rhino 5. 90% of the time we use the SolidWorks plug in to move from SolidWorks to Keyshot. 90% of the time it is a one way process. But the 10% when we need to go back and edit in SolidWorks then return to Keyshot, of that 10% probably 99% of the time we need to reimport from scratch as live linking does not work a lot of the time.
Our biggest issue is when working with configurations or when changing the visibility of parts in SolidWorks.
A typical scenario is this. We set up a configuration in SolidWorks with some parts hidden (in the configuration - we link display states to configs). We then export to Keyshot, set up a render, then realise we needed to show some parts. Switch back to SolidWorks, show the parts, update the config, live link back to Keyshot and....well...99% of the time what happens is ONLY the parts that have been unhidden in SolidWorks come through, everything else vanishes. So we close Keyshot and reimport the lot again from scratch.
Keyshot is its own worst enemy in this, being so quick and easy to use, we just say, what the hell, and reapply everything - usually only takes a minute or so. But if you have spend ages setting up labels and textures it is a real pain when this happens.
Another issue is that the plug in does not appear to handle labels applied in SolidWorks - it just ignores them (leaving you to set up labels in Keyshot, which is really not great - full explanation see textures forum thread)
Now for Keyshot this might not be important yet. but in coming months/years it will become important as SolidWorks Visualise actually starts to become more integrated. Currently Visualise is probably one of the worst pieces of software I have used in recent years, but that will get better, and the integration with SolidWorks will improve. So for v7 guys, can you give the SolidWorks linkages a kick please. No matter what the marketing teams of competitors suggest, SolidWorks is still the number 1 3D CAD app for product design, and will be for many years to come. I want to ensure Keyshot stays at number 1 for visualisation of SolidWorks files as well.
