TSL | hsbTimberPercentage – Roof

This document will show you how to calculating the wood percentage / TimberPercentage with the hsb_E-TimberPercentage tsl for determining the RC value of elements for the BENG – NTA 8800.

Where can I find this tsl?
This is stored on your C:\Program Files\hsbcad\hsbDesign25\Content\Dutch\TSL\hsb_E-TimberPercentage.mcr

Version of the TSL 2.2 available from V25.1.72

The TSL places an outline and PLine around zone 0 and takes the area of all beams within the area of the automatically placed PLine.
Beams narrower than half the element thickness are not included in the calculation.

If you are not familiar with DSP: DO NOT TOUCH IT!!

How to run the TSL

When executing the hsb_E-TimberPercentage.mcr tsl an element must be selected.
If nothing is entered in the properties at the property “Profile Name” then the outline of zone 0 of the element will be taken.
This means the outline where the openings are taken from.
See also the example below where the outline is visualized with a red/selected line.

Outline based on details

In the DSP Details, just like with the walls, a cut must also be placed with _ infront of the name.
This can be attached to a variable in a DSP so that you can set the Profile from the parameters of the detail.

From within your detail you need to indicate where the base reference point is in your DSP..
