custom windows & doors - no parametric options available!

I just tried SHAPE and I am missing the following, in order to consider Shape a serious software, and not just a toy to play in 3D:

1) all standard windows & door do not display their parameters:

• their positioning in the wall section (how far from the one side and the other)
• the dimensions of their profiles (thickness of frame, of glass, etc.)

2) when producing a custom win/door, there is no possibility to set the above mentioned parameters. Instead, Shape uses the SAME unknown parameters from the STANDARD components (win/doors).

3) there is NO documentation available for SHAPE, as for how to seriously setup such customised parameters.

I hope some community member could explain how to solve this in a simple manner (as simple as Shape claims to be!)
Is there perhaps any way to control, detail and CHANGE these missing parameters when importing a SHAPE 3dmodel into "Bricscad BIM"?

Otherwise, all this seems simply like a joke! I now understand why Shape is free.
No documentation (except videos and their transcripts), no possibility to easily change the parameters, and being locked into them (as you cannot specify different ones).
In fact, the creation of "custom" win/doors is just a play with their shape, not with their technical details.
No serious architect or engineer would use this Shape to really plan a building, at least not in the way it is described in the videos.

By starting to do something else (like defining custom components, building them from scratch, etc.), the SHAPE software becomes useless, as its point (the claimed "simplicity") turns out to be not of any use, when needing custom elements. If you use any other software (like Archicad, Revit, Nemetschek or cheaper ones like ArCADia, etc.) you can always set the parameters of a window, in an extremely simple and fast way. Not by starting a 3d-modelling task (in order to create some general custom object from scratch), but just by indicating some dimensions of that window.

By the way:

• i measured the frame of the standard windows components: it is 5cm wide. I ask where did Bricsys find european windows with 5cm thickness of the frame? Perhaps in Holland, where there is mild weather and no cold winters? Any usual isolating window from the EU is about 8cm thick. So why not start with usual dimensions, if shape wants to keep "simple"?

• Some windows are positioned 7cm away from the exterior facade plane, others 9cm. You cannot know it in advance, except you use them and measure each of them.

• If you start to move the window in the opening of the wall (to change its distance to the facade plane), it starts to behave erratically (the wall gap disappears, or is partially closed, etc.
