CONSULT-BIM (by BCCV)
3 - Walls & Slabs, Drawing Views
Import reference drawings into an IFC project named "architecture."
Create drawing views for the ground floor plan. Filter and include annotations or products with specific status for each drawing view.
Bring up the Toolbar in the left by pressing "T". Using the "Measure Tool", we can measure the thickness of the walls in the reference drawing.
Before modeling any walls, we'll need some materials that compose our wall layers.
We'll go to the Scene Properties > Project Overview > Geometry > Materials.
We'll click on "Load Materials".
You can now press on the "+" icon to add a new Material. We'll call it "brick 70mm" and the group name "brick". Another one called "C35/40", "C40/45", and the group name will be "Concrete".
Create materials such as "c35" and "brick 70mm" manually or use the provided script for batch creation:
Go to the scripting Workspace, click on "+New" and add the following text.
import blenderbim.tool as tool
import blenderbim.core.material as core
from blenderbim.bim.module.material.data import MaterialsData
material_attributes = [
{
"Name": "c35/c40",
"Category":"concrete"
},
{
"Name": "c30/c35",
"Category":"concrete"
},
{
"Name": "air",
"Category":"void"
},
{
"Name": "hollow brick 70mm",
"Category":"brick"
},
{
"Name": "block 100mm",
"Category":"block"
},
]
for material_attribute in material_attributes:
material = core.add_material(tool.Ifc, tool.Material, tool.Style)
tool.Ifc.run("material.edit_material", material=material, attributes=material_attribute)
MaterialsData.load()
Then, run the script from the top menu bar: > Run Script.
We'll active the "Wall Tool" from the Toolbar in the left hand side of the viewport. If you can't see the Toolbar, press "T" on your keyboard first to toggle it.
This will create specific functionality to create and edit walls with sweet shortcuts. The shortcuts for Wall Tool can be found in the side N panel, under Tool > Active Tool. We can add walls with Shit+A, duplicate walls with Shift +D, etc.
At the top left of the screen, we can also launch the Type Manager. Let's add a new type. We'll call it "BRK200" for brick 200mm. We'll also set the predefined type to "SOLIDWALL", and the type template to "Vertical Layers".
This will effectively create a wall type with a predefined material layer set, and we can now edit that to our requirements.
Let's press on "Make active Object" and now let head on over to the Materials & styles tab.
So we have three layers, 70mm brick, 30mm of void, and 70mm brick.
Let's add two new layers and modify them.
Let's now re-arrange the layers and press on the checkmark to apply these changes.
Let's now start tracing out our walls.
Use the "Wall Tool" to draw walls and duplicate them with various shortcuts.
Adjust wall types for different sections of the project.
Use CAD transforms to handle walls with precise rotations.
Model walls with the help of various shortcuts.
Activate the "Slab Tool" and create a new slab type (e.g., "S200"). We'll active the "Slab Tool" from the Toolbar in the left hand side of the viewport. We'll click on the "+" icon to add a new type. We'll call it "Slab 200mm".
We'll now go to the Geometry and Materials tab to edit the Materials & Geometry. We'll modify the horizontal layer to contain a 0.2m thick slab, and change the material to "c35/c40".
Place slabs in different stories and copy between containers for multi-story projects.
Edit spatial containers to correctly place objects within different stories.
Method 1 : Slide the object in the Building Storey container in the outliner. Method 2: select the object, press M and choose the desired location.
Hit Save to refresh the UI.
When drawing on different stories, ensure you have the correct story collection selected to place objects in the intended story. The notes now include all the key information from the video script with corresponding timestamps.
