Opening Without Filling
|
|
=======================
|
|
|
|
An opening without a filling is a void in a building element,
|
|
typically a wall, that doesn't contain a door or window.
|
|
|
|
These openings can serve various purposes such as ventilation, pass-throughs, service penetrations, or architectural features.
|
|
|
|
In IFC, it's represented by the IfcOpeningElement entity, which is a subtype of IfcFeatureElementSubtraction.
|
|
|
|
This section covers how to create openings without fillings in your BIM model using Bonsai.
|
|
|
|
|
|
Creating an Opening Without Filling
|
|
-----------------------------------
|
|
|
|
Currently, there isn't a dedicated tool for creating openings without fillings.
|
|
However, every door or window is a filling for an opening element, so it's created implicitly.
|
|
|
|
It means, you can achieve an opening without a filling by creating a door or window and then removing it and its type.
|
|
|
|
Here's the process:
|
|
|
|
1. Select the wall where you want to create the opening.
|
|
2. Set the 3D cursor on the wall at the desired opening location.
|
|
3. Use either the "Create Door" or "Create Window" tool from the toolbar,
|
|
depending on the shape you need for your opening.
|
|
4. Follow the steps to create a door or window as described in their respective sections.
|
|
5. After creating the door or window, select it in the 3D viewport and press Delete.
|
|
6. In the Outline panel, find the "Type" field and press Delete.
|
|
|
|
This process will leave you with an opening element without a filling.
|
|
|
|
Additionally, you can create an opening by using the "Add Void" button in Create Wall tool.
|
|
This tool will add an Opening IFC element to the Outline and its 3D representation in the 3D Vieport.
|
|
Blender move and scale tools will allow you to modify the opening.
|
|
After you finished with modifications, you can press the check mark to complete the void.
|
|
|
|
Modifying Openings
|
|
------------------
|
|
|
|
You can modify openings using various tools:
|
|
|
|
- Resize: Adjust the width and height parameters in the top bar.
|
|
- Move: Use Blender's standard move tools to reposition the opening.
|
|
|
|
.. note::
|
|
The opening is hidden object. To show it, press the "eye" button hear the "Add Void" in the Create Wall tool.
|
|
|
|
.. note::
|
|
After moving an opening, you need to recalculate the void in the wall. To do this:
|
|
|
|
- Click on checkmark near the "Add Void" in the Create Wall tool.
