Connect/implement calculating quantities functions

[maxfb87]

This is not a issue but a feature request about quantities calculations.

The Goal

The goal is to connect the already implemented calculating quantities functions with the quantity property.
If there isn't the calculating function or the existing function is not suited, it's necessary to write a new calculating function.
All the Qto Psets and the Quantity Properties have been extracted from IFC4x3 schema and reported into the following .xlsx attached files:

• "qtos_all_quantities.xlsx" has all quantities (file: qtos_all_quantities.xlsx)
• "qtos_all_quantities_sorted" shows all quantities, grouped into qto pset (file: qtos_all_quantities_sorted.xlsx)
• "qtos_all_quantities_counted" shows how many quantities there are (file: qtos_all_quantities_counted.xlsx)

How to help

Only two files are involved, both stored in "/src/blendebim/blenderbim/bim/module/pset"

• "qto_calculator.py" that has all calculating functions (for example get_height that returns the height of an object)
• "calc_quantity_function_mapper" that has a dictionary called mapper that connect the "qto_name.quantity_name" with the function (for example, "Qto_WallBaseQuantities.Height" with get_height)

So, to help, it's enough to work on the mapper to connect the quantity with the proper calculating function.
There are 346 quantities, so help is welcome :-)

Of course, many quantities are repeated so, presumably, it will be used the same function (for example, there are 36 "Lenght" and presumably "get_legth" is a suitable calculating function).

After the mapper dictionary has been modified, to check if the function works correctly, open blendebim->object property panel->IFC object quantity set -> edit the qto and there will be a new icon next to the quantity

What's the best way to help / see progress on the number of mapped quantities? Is it possible to either share a spreadsheet, or dump it all out to the calc_quantity_function_mapper.py file with "None" values for the ones which are not yet mapped?

[maxfb87]

Yes, good idea.
I write all quantities with None value where the calculating function is not assigned.
I'll do a PR.

Unfortunatly, i have not yet found a way to update automatically the issue accordingly with the file, but i think also that the file is enough to track the progress.

Indeed if you write all with None and then update the file periodically we'll know :)
