Sorry if my posts have been unclear - hopefully it’ll help if I back up a bit:
I have been building a model in Sketchup for the construction of a new house, with the intention of then sending the model to Layout to generate 2-D plans to submit to the local council for approval to start building.
I did begin the model at the origin and on-axes but with the house not being aligned with any of the land boundaries ( in order for the house to face north), none of the boundaries meeting at 90 degrees and also having a shed also unaligned to both house and boundaries because of land slope consideratons, it didn’t take long for components to be built with axes being moved around (and then left as is and not repositioned).
Geo-location was done through the Add Location feature in order to look at how shadows played out throughout the year and so figure out a good width for the eaves and particularly the verge on the west side of the building.
Everything seemed ok - I set up my section cuts and scenes, (checking everything with the SU tape measure rather than the dimension tool), sent the model to Layout and started dimensioning the 2-D plans.
This is when I hit trouble, with the unexpected dimensions reported by layout on the section cut I attached in my first post. After much investigation, I discovered the the problem wasn’t in Layout, as I found how to reproduce the effect in SU with its dimension tool.
Through the discussion in this thread, I’ve come to some appreciation of the characteristics and importance of the global axes. But SU/Layout behavious still seems odd to me. After all, drawing axes can be moved around to facilitate the building of components and surely dimensioning will normally be required relative to those axes. And isn’t layout there to specifically generate 2-D documents from specific viewpoints and why doesn’t it respect dimensioning perpendicular to the view?
I must still be missing something. Any advice on how to straighten out my thinking and how to fix my model to generate accurate 2-D plans would be much appreciated.
