“Revit Building has even labeled the height and width dimensions. Use the reference planes to create your sketches for your door geometry. If necessary, modify the dimensions to the sizes you want to create for your first door”

Typical Revit Ontology: use the the off-the-shelf givens we’ve helpfully provided for you, or jump out one level and change the meta-rules as req’d. Typically, they make it sound easy, when those three sentences probably take a half day to execute. Breathing or sailing, it ain’t.

Will do a proper repost and spread the virus once I get home.

To prove I am even geekier than you ever dreamed…

“We transferred ourselves therefore to that part of the boat that was highest out of the water, in order to lighten that part which was down in the sea, and so if possible, but our own added weight depressing the former, to bring the whole again to a level; but it was all of no avail…For some time we thus ineffectually struggled to bring to an equilibrium the vessel thus balanced on the waves: but the wind suddenly shifted to the other side so that the ship was almost sent under water, and instantly that part of the boar which had been down in the waves was now violently thrown up, and the part formerly raised on high was crushed down into the waters… the same thing happening a third, and a fourth, nay. many times, we thus imitated the motion of the ship”
