I am trying to annotate a welded metal structure that we modeled in SU for a client and contractor and am hitting some roadblocks. Coming from a CAD background I know how what the end product should look like but we almost never annotate in SU - it is used primarily for graphical representations so I'm a bit lost. I digress - I need some welding symbols that will behave like the SU text & leader objects do. i.e. follows the camera, scales like text and so forth. I also need some leader arrows, although for the short time I can fake it and make a component. Do either of those objects exist - as components, scripts or something else?

We use SketchUp at work quite a bit to give clients renderings of different building options - showing different facade features & colors (parapet vs. no parapet, brown vs. black) and have been doing it with different models which the more I go about it the less efficient that seems. What would be the best way to go about doing this? Our output is usually images for the client and a quick animation.

I apologize if this has been asked. I skimmed the forums but didn't see anything and am not sure how best to search for the topic.

Thanks!
