LayOut is not adequate for professional use, a point discussed in detail in this thread.
Yes, I do agree. There seems to be little point matching feature-for-feature a major desktop publishing program like InDesign. However, LayOut should still be able to generate a standard set of construction documents from a Sketchup model, which might consist of up to fifty 24 x 36 inch pages, 150 or 200 viewports, extensive text, etc.
LayOut should absolutely clear that bar, because (a) it is the only DTP supporting Sketchup viewports, therefore Sketchup Pro users should get what they already paid for, and (b) Trimble’s main business is construction, so it seems only appropriate that their desktop publishing solution should publish industry-standard, bread-and-butter construction docs, and do so relatively painlessly. Yet, it does not.
