This 'Quick Select' panel enables you to short-cut the steps described above by making certain key choices here rather than in the panels above it.

The check boxes and buttons affect the listed layers in the central panel above them and they can change the contents of this list according to your selections.

Note: When a check-box option appear to be 'greyed-out' (an indeterminate state) it means that the status and settings of layers in the list above will not be altered during import.

For example, let's assume you want to exclude layers containing 'openings'. These elements represent gaps in wall which Entities can pass through (like a doorway without doors). If imported, this CAD will automatically be classed as 'presentation CAD' but you might prefer to exclude it because there's a chance it would look like an obstruction.

To do so, you should uncheck the box marked 'Import', then type 'opening' into the 'Contains' field and then click the Contains button. This would exclude all layers with 'Openings' in their name from eventual imports.

To quickly select layers:

1. For each type of selection you wish to make, check or uncheck one or more of the labelled options to define how imported layers are used:
   • Import – check this box to import layers; uncheck to exclude the layers from import.
   • Simulation – check this box to include layers in simulations but not necessarily as part of Auto-navigation; uncheck to exclude.
   • Auto-navigation – check this box to include layers in LEGION Model Builder' Auto-navigation calculations (when you check this box, 'Simulation' is also checked); uncheck to exclude.
2. Click one of the following buttons to apply the check-box options to:
   • All – all layers in the file (you may wish to uncheck 'Hide layers that don't have slabs' if you think you are missing some.
   • With slabs – apply to all layers containing IFC 'slabs'.
   • Slabless – apply only those layers without IFC 'slabs'.
   • Contains: – before clicking this button, enter a text string into the adjacent field to identify layers to import. This field is not case-sensitive and you don't need to enter whole words to identify elements or labels. It works in the same way as the 'Exclude IFC containing:' field described above. When you have entered your text, click Contains.

   After each of these actions, the list of selected layers should be updated to reflect your choices.

3. Continue to make quick selections if you need to refine your layers further.
