I a residential designer in Northern Ca. which is the fastest way to do a building cross section?
Hello:
I use XRef's of the floor plans (rotated and X-Clipped appropriately) and good ol' fashioned orthographic projection to get the horizontal locations of walls. I set up the floor lines carefully, and then I draw the major outlines. The eaves and plate details and the roof pitches are critical to get right, as well. I switch to Relative Cartesian to draw the roof pitches -- I enter an 10.5/12 pitch as 0.120 Enter, 0.105 Enter, and then mirror/copy and 2-line trim to get the peak.
I then use the first section to help draw any subsequent sections.
Does this help?
