[Edit] Better Workflow to Model and Revise a Complex Building, Assemble Parts, Parametrically and Efficiently? - 1

[paullee]

Workflow experiment on 1st point

1. Discrete Objects Unable to be Assembled Difficult for Design Development [Edit]

> Currently in the experiment, a single underlying master sketch and a nos. of dependent sketches is used to create Arch Wall objects
> All arch objects, each of which are numbers of walls, are constructed on top of sketches of numbers of lines / edges
> Sketches are grouped currently according to wall thickness
> Totally abandon link to external geometry / Map to Face or Vertices etc.
> Use sketch's mapmode to kind of assemble / link sketches and arch objects against each other
> Use a (group of) Arch Axis to 'place' all the relevant sketches or all the Arch Objects similarly to kind of 'assemble' the parts

> Now, the tower, with all parts / arch objects 'assembled', move/rotate altogether with adjustment of 1 axis
> A master sketch change layout, other dependent sketches follow and arch objects follows
> A single Axis system control and can be edited as to how the tower typical floor are repeated
> Arch Spaces are built upon the sketches

Would be Better With / Pre-requisite: There are several problems dropped into as shown in the videos below. It seem to have this workflow work efficiently, problems encounter should be somehow resolved or addressed

> Ability to (auto) custom name to each edges in Sketches / Draft Wire

Videos of the Experiment [Edit]
ArchObjects Creation 'based on a Sketch'
- 4 'box' objects in the model shown
- note the numbers of parts form a 'box' object 'based on 1 sketch' ( a number of 'dependent' sketches on top )

Rotating a group of ArchObjects Walls, Windows, Doors
- note rotating an axis, rotate all parts together, walls, doors and windows
- it start rotating at about 17s, finishing at about 1min!
- find some broken walls
- touching here and there the underlying sketches, expression, force recompute 'fix' the model to expected shape

ArchWall (Closed) flip in Left / Right Direction
- in addition to random broken / arch wall creation problem
- a wall object, closed with 4 sides, is found flipped inside-out, left to right (or vice versa)

Stretching the Underlying Sketch Stretch the Model, Relocating Doors and Windows
- note about 1:30' room dimensions are adusted
- model updated in about 5-10s (w/ some problems and 'fix' as above)
- note the doors stick to next to the dividing wall
- the window still keep near the corners
- about 4:10s, another attempt to stretch /alter the room dimensions

Thanks for the patience. More video to share on 2nd and 3rd points after some sleep.
