Arch Profile

Description

The Arch Profile tool builds a parametric 2D profile object. This object can then be used as a base in different other tools that perform extrusions, such as Arch Frame, Arch CurtainWall or Part Extrude.

See the list of available presets.

The profile tool is also integrated to the Arch Structure tool, all preset profiles are also available there.

Usage

1. Press the Profile button
2. Select a preset in the tool task panel
3. Click a point in the 3D view to place the profile

Properties

Data

• Height: The overall height of the profile

• Width: The overall width of the profile

• Diameter: The diameter of the profile (circular profiles only)

• Thickness: The thickness of the tube wall (circular and rectangular hollow profiles only)

• Web Thickness: The thickness of the profile web (H and I profiles only)

• Flange Thickness: The thickness of the profile flange (H and I profiles only)

Adding custom profiles

An additional CSV file can be created by the user, containing custom profile definitions. It must be named profiles.csv, and placed in

{{Code|lang=bash|code= $FREECAD_USER_DIR/BIM/ }}

The $FREECAD_USER_DIR can be obtained from the Python console:

{{Code|lang=bash|code= FreeCAD.getUserAppDataDir() }}

The contents of your custom profiles.csv file must be modeled upon the same rules as the profiles.csv in the source code.

The CSV file must contain one line per available profile, formatted as follows:

• For C profiles: Category, Name, Profile class, Diameter, Thickness
• For H, U and T profiles: Category, Name, Profile class, Width, Height, Web thickness, Flange thickness
• For L profiles: Category, Name, Profile class, Width, Height, Thickness
• For R profiles: Category, Name, Profile class, Width, Height
• For RH profiles: Category, Name, Profile class, Width, Height, Thickness

All measurements must be in millimeters. Possible profile classes are:

• C: Circular tube
• H: H or I profile
• R: Rectangular
• RH: Rectangular hollow
• U: U profile
• L: L profile
• T: T profile

Additional profile types can be created, but a corresponding class must first be defined in ArchProfile.py.

Scripting

The Profile tool can be used in macros and from the Python console by using the following function:

profile = makeProfile(profile_list)

Where profile_list contains the different elements of a list in the CSV file.

Example:

import Arch
Arch.makeProfile([0, 'REC', 'REC100x100', 'R', 100, 100])

Where the first element of the list is an order number that is not used yet.
