[SketchArch Add-on] - Automatic Building Generator

Based on the idea of HomeMaker-Topologic, created a short script on FreeCAD.
In FreeCAD :

1. Make a single-line Sketch of a building layout, run the script (Topologic-Homemaker like)
   (On 2nd Gen i3, it needs 10s)
2. You get the wall, slabs, roof, windows on external walls

(Just proof of concept at the moment)

Q :

• Wondering how to identify a wall access from a corridor to automatically place a door, from a common wall which divides a room from another (thus not placing a wall by the script) ?
• Found Face.FacingToward() method ( https://topologic.app/topologicpy_doc/t ... cingToward ), seems needs input of direction to test to return result . Any other method available which return the direction?

Amazing

I've recently been working on a similar tool.
The tool uses simple shapes such as lines and rectangles as a base to create the building.
Here's the video:

We can collaborate on this if you are interested.

Feel free, would post my script when there is a gap

Maybe you can outline the goal of your tools, maybe there are more peoples who are interested in collaboration.

With this script I intend to create a tool that facilitates the process of creating BIM construction models, my objective is to reduce the time it takes to model a building, so the architect will be able to generate and test several different floor plan layouts in a short time, This way, the professional will be able to focus on their real work, which is designing, and will not waste time on modeling. With a simple sketch it will be possible to define walls, windows, doors and their types. I also intend to implement the creation of floors and roofs automatically, with the user simply defining a few parameters.

@paullee how your window position is given?

Thanks @Maykow

Some steps in typical architectural workflow take time, e.g.

1. Setting-out a floor plan and revising
2. Placing Door and Windows

For reference, I found using a Sketch helps - augmented by features in the experimental SketchArch add-on. Then placing Door and Windows is kind of Parametric Placement of Arch Objects

For further discussion

@johnwang

It is kind of parametric, user (of the SketchArch addon) select in the Snap Preset attribute - See 2. Parametric Placement of Arch Objects Intuitively


" Added Attribute -
(Master Sketch Subelement) Snap Preset : Allow users to snap to a Wall Axis e.g. at -

• MidPoint
• 1/4 (of WallLength from StartPoint)
• 1/3
• 2/3
• 3/4
• AxisStart
• AxisEnd
• Custom Value

With 'Custom Value' selected, below Attribute -
(Master Sketch Subelement) Snap Custom : Allow users to snap to any value e.g. in fraction in formula 2/9 etc."
