How to use "BC_Subtract layers" ?

Hi. I just downloaded the demo version of BricsCAD and I read some documentation regarding on how to get up and running.

I'm designing furniture and I need to insert a lot of dowels and other kinds of connectors between the elements of a furniture unit and for this reason I'm very interested on how I can get automatic booleans between objects, respectively the connectors to create holes into the elements of the unit.

Searching for options to automate my work I stumbled upon this article:

Top 15 reasons to get BricsCAD v17

where I found something interesting:

13_User-defined Component-based parametric features allow Boolean operations through the use of BC_UNITE and BC_Subtract layers in the component definition.

I searched for more information regarding this topic but seems that I can't find. I tried by myself to do a Component definition that uses automatic booleans but I just can't figure-out how to do it.

Please, if somebody knows how to do it to post an answer. Thank you.

    Hello Dacicusan,

    You can find an example of parametric component in BricsCAD installation directory ( ...\Bricsys\BricsCAD V17 en_EN\Samples\Mechanical\component_based_features )
    If you open hole_with_edge.dwg component, you'll see it consist of two solids: green and red. They painted just to distinguish. Colour doesn't really matter.
    So the green solid is placed on BC_UNITE layer and will be united with the target geometry
    The red solid is on BC_SUBTRACT layer and it will create a hole.

    Here is short video of how does it work https://youtube.com/watch?v=WR_FmClnmT8

    Thank you for reply.

    On MacOS this is located under: /Library/Bricsys/BricsCAD/V17/Samples/Mechanical/component_based_features
