Tool Of The Day:

"Wall Splitter"

Today we're going to select multi-layer walls and break them down into new individual walls to match the same wall geometry.

Today We're Practicing:

>>>

Exploring Element Attributes

>>>

Curve Offset⭐

>>>

Compound Structure⭐

>>>

Duplicatinjg Instances/Types ⭐

Let's Create

PLAN

Let's Split Some Walls…

Sometimes we want to break down our multi-layer walls into individual layers for very specific control.

So, the Goal for Today:

Create a tool that can look inside Wall Layers and create individual WallTypes that will be placed in exact same location as the layer in full selected WallType.

Here's everything you might need for today's challenge.

Coding Blocks

Pick a Wall

Read Layer Information

Create New WalLType per layer

Offset the Wall Curve per Layer

9. Join All New Walls

Skip Membrane Layer

Read Wall Layers

Generate New Type Names

Get Existing / Create New WallType

Create a New Wall Instance (Duplicate)

Remove Hosted Elements

Pick a Wall

Read Wall Layers

9. Join All New Walls

Remove Hosted Elements

EF-Notes:

🔸Curtain Wall

Curtain walls do not have CompoundStructure with layers and materials like regular walls do

🔸Copy Elements

When you copy elements you'll also inherit all parameter values. However, it will also copy hosted elements if any.

🔸Stacked Walls

Don't forget about stacked walls. You can also break them down into layers, however the Sweeps/Reveals will be trickers to reproduce if necessary.

🔸Join Layer Walls

If you have hosted elements in a wall that you split, you need to join your wall layers. This way the opening from hosted object can go through all joined walls. (if family allows)
