A regular problem I have is accurately dimensioning things that are curved. This is partly to do with the fact that in SU there is no such thing as a true curve. So whilst it is easy to pick straight line intersections for dimensioning, curves are much more testing.
Here is a case in point. I need to show the centres of the rod sections as well as the centres of the round holes. Doing that approximately is easy but being mm perfect is harder.
Does anyone have a cunning way of making this kind of thing easy?
Number one thing I would recommend is to get rid of the extensions in the style at least while you are working in SketchUp and LayOut. If you want those extensions, turn them on for the style after you’ve completed dimensioning and re-render the viewports.
Second, I find it easier to do the dimensioning with viewports rendered as Vector.
Make sure circles are identified as circles in SketchUp so you can infer to their centers when dimensioing.
Zoom in when needed to make it easier to find the centers and endpoints.
You could also add guidelines in SU that are on their own tag at the center of the circles. Dimensioning off of the lines might be easier and you can override toggle visibility off for that SU tag in LO later if needed.
Or you could draft some dashed lines in LO on top of the viewport and make them a scaled drawing, then dimension off those - you could put them on their own layer and toggle visibility off for those too.
