This is the process I go through:
I work on my drawing, all layers but the title block are 1/4" as that is what fits on my page.
I goto the Export function and set the scale size to 1:1 (which is the scale of my Title Block.
I leave all default settings as is then export.
I don't use VP or Sheets in my drawings as they are extremely simple and I honestly never learned how to use them properly.
When my co-worker opens them in ACAD or AGI, both of which take the DWG it opens in random scales, the last time I belive it was close to 1/8" scale.
