How to Use the Thread Feature in BricsCAD Mechanical

Quick answer: DMTHREAD creates a thread feature. Worth noting: like several pages in this hub’s earlier BIM section, this source’s own title reads “BricsCAD Lite & Pro,” a general tool documented within the Mechanical section here.

The Thread Feature’s Parameters

• Thread standard: a set of standard threads, extendable with a custom thread; changing the standard automatically rebuilds the geometry.
• Pitch: the thread’s pitch.
• Length: the thread’s length.
• Diameter: the thread’s diameter.
• Type: male or female, or set to auto to have it determined automatically.

Adding a Thread Configuration

1. Right-click the feature in the Mechanical Browser panel, confirming the same context-menu workflow covered on this hub’s Mechanical Browser page.
2. Choose Replace Table.
3. Select a CSV file following this format:

Size,Diameter,Pitch
Name1, Diameter_value1, Pitch_value1
Name2, Diameter_value2, Pitch_value2
Name3, Diameter_value3, Pitch_value3

Frequently Asked Questions

What happens if I change a thread feature’s standard? Its geometry rebuilds automatically to match the new standard.

Can I add custom thread sizes not included in the standard list? Yes, extend the list with a custom thread, or replace it entirely by importing a CSV configuration file via the Mechanical Browser’s Replace Table option.

What does setting the thread Type to auto actually do? BricsCAD determines automatically whether the thread should be male or female.

Where do I import a custom thread configuration table from? Right-click the feature in the Mechanical Browser panel and choose Replace Table to select a CSV file.
