status update.
so far, i have been able to model the moveable solid wall portions, fairly close to the desired motion constraints. there are some movement parameters that i am not sure of how to control (like when a wall must stop rotating or an extreme of rotation) but the restraints that i have been able to put into play have the walls moving as desired.
step 1: i exported the pre-existing plan (in the cracked form) as an .igs file in order to create the base plan to draw from.

step 2: from the base plan, i projected points into a new sketch for the outline of the core's floor, as well as a new sketch for the locations of the walls. i then isolated the projected points from the cad background to allow the walls to float.

step 3: in order to control the movement of the walls, a few restraints were put into play by creating a new sketch consisting of guides for the walls to rotate and slide on.

step 4: in preparation of the ceiling portion of the walls, i again projected and isolated the previously drawn points from the cad file, and drew guide lines to their respective points along the walls. i also gave some dimensions to the walls in order for them to maintain their shapes upon movement.

step 5: using the height parameters i created for the height of the walls and the pitch of the ceiling, i projected the points to planes controlled by the height parameters.

step 6: with the projected ceiling points i drew a polyline between the three corner points to create their outlines. i then made a plane for each ceiling orientation and offset a second one controlled in distance by a created 'ceiling thickness' function. i then extruded the polyline as a 'pad' which created the solid. finally, i created a 'pad' for each wall segment in the same part body set, and extruded it 'up to last' which automatically booleans the wall and ceiling pads into a single solid.

the height parameters i created allow for easy adaption of the wall height and pitch height.

step 7: wall movements. there are some parameters and restraints that still needed to be created/figured out in order to avoid the over rotation of a few of the wall pieces, but the general control of sliding the first wall to initiate the motion is happening, which is encouraging.
