We use Sketchup and Layout to create our design concepts and then create Construction Documents. However sometime we need to make changes to these construction documents. Thus we have a need for a easy Revison Cloud tool similar in function to that in Autocad. It could even be a line type.
I don’t know that tool, but if you only need to color lines to show modifications, you can us the style setting “Color: by material” and paint them with a color.
SketchUp or LayOut don’t support complex linetypes, but a workaround could be built in SketchUp as a dynamic component (an arc component set to be repeating). It would be better if it could be a LayOut page element, like all 2D annotation elements.
We use layout for our construction documents as well. We created various sized and shaped revision clouds and saved as a scrap book in layout. Once a revision has been implemented you can place a revision cloud from the scrap book and resize to suit the area of change.
I wrote this tool ages ago http://sketchucation.com/pluginstore?pln=RevCloud
It’s a script to draw a 2d revision-cloud in SketchUp, following the cursor.
You could then copy that line-work into Layout and add it to a Scrapbook…
This is a very basic drafting feature that needs to be implemented
