Apologies in advance if combining multiple questions in one post is breaking protocol -- all are on same project so thought it best to upload file and related questions all in one place.
Using HDP 2017, several questions in order of priority, all start with "how do I"
1) Build a gable wall that exists only above another roof plane? In this case I am remodeling and peeling back a gable to intersect with new shed (skillion) roof at a crazy angle. Tried placing in attic with various structure and roof settings. This is as close as I get - when I stretch in orthographic I get odd geometry so I know there is some conflicting settings on some wall or room but can't figure it out. Similar problem with wings under shed roof over clerestory (left side is correct) and another gable over garage.
2) Manually place a gutter (ultimately will be a box gutter feeding sump, not sure it's feasible to do in HDP?)
3) Show roof dimensions in either 2D birdseye rendered "normal" camera or othographic elevation? Same question applies to showing rendering floors from birdseye perspective. (I suspect it's just not possible in HDP.)
4) Show actual thickness of shed (skillion) roof in orthographic views? My roof settings are 12+ inches but only showing 3-4.
5) Force a wall to rebuild after changing its structure and/or roof settings
6) Delete deck framing (other than one member at a time, after forgetting to turn off "retain framing")
7) Stop room dividers from turning themselves into invisible interior walls
.plan file is 36MB (over the 25MB limit) so here is a link to it . A bit embarassed to show you the mess I've made of all the experimental hacks I've tried. I know it's not the best tool for this complex a roof, and certainly not the best project for an amateur, but here I am. (working with a structural engineer FWIW). If anyone has tips for getting Chief for less than thousands of dollars I should would love layers about now
