Your initial challenge to modeling an existing door to match the point cloud survey may be secondary to the additional challenges for walls, floors, and other sloped or deformed structures in your building.
Rather that adapt parametric families to these challenging conditions, I would consider whether it is acceptable to model in place existing conditions rather than creating a overly complexe parametric families that will warp to fit. This may be informed by your role and the extent of the work to be required.
For example, if the building will be gutted, and the replacement constructions will be orthogonal, why bother with a warped parametric door. If modifications are to be minor and/or the new construction required to match the existing deformation, those will help decide to invest in the time and effort the create warped parametric doors, walls, beams, etc.
This said, a quick way to simulate a warped door and frame is with an embedded curtain wall family which can allow you to adjust to uneven deformations of a trapezoïd. Although it does seem that the frames were deformed as parallelograms which is probably simpler to modify a standard door family as @syman2000 suggests.
I've recently used this technique for a sloped walkway where the curtain panels needed to stay perpendicular to a sloped floor. The idea is:
- Place a curtain wall to automatically cut the compound wall;
- Edit the wall profil to rotate the top and bottom to the desired angle. These angles may even be different in the case of a trapezoïd;
- Edit the curtain grid's vertical angle if the jambs are also inclined;
The down side is that if you want a custom curtain panel (ie include swing lines), it will have to be an adaptive curtain panel.
