I was asked to create a sketch of some proposed construction footprints, but I seem to have forgotten everything I knew about parcel editing. I haven't been given a survey transit, just a sketch on what looks like Google. Two rectangles with a ten foot offset from existing buildings, and a requirement to align to those buildings.
I thought I would start be editing in a new FC for the alignment edges of the existing buildings, then a new feature class for the 10 foot offset, then copy parallel to get something to snap the one side of the new building footprint to, but I already couldn't remember how to add a line both perpendicular and a known distance. I suppose I need to know how to do this when constructing the building polygons as well. It's such a small project, I don't think I would need to define a topology just to eyeball in a ten foot parallel setback.
How about a nudge in the right direction? Why can't I remember how I have done this?
