4.2) Filter IFC Elements
The Filter Elements function allows the user to filter the IFC model elements, according to specific
and well-defined criteria (see the image).
The first window shows all the active plans and all the active structural objects. Each structural element is followed by a number that indicates the quantity of the same type of elements in the model. If structural objects are missing, they appear disabled.
The user can add or remove the check on the titles (FLOORS and STRUCTURAL OBJECTS). If you add the check, you add every check inside. If you remove the check, you remove every check inside. The user can disable or enable the floors. In this case, the number of the structural objects will be automatically updated.
By clicking on the structural items grid the list of the materials used for the selected object type is automatically filled. Each material has a check mark for the display management (if the material is checked the filter considers the structural object associated to the displayed material otherwise it becomes invisible). The objects whose construction material is not defined are classified as Not defined material.
In the attached example image, the structural object Beams (consisting of 8 beams) is made of the following construction materials: C20/25, C12/15, ACSS1 Conifer and Not defined material.
When the user presses the OK button, the graphic area is redrawn according to the filter window user’s choices. If the user returns to the filter window, finds the checks and selections as previously defined and can change them as he desire.
