🧾 Wall Flashing Overview
The Wall Flashing command generates flashings for opening trims and corners of walls. When you select Flashing, the Wall Flashing dialogue box displays the flashing/trim material to be used on each line type in your wall model.
To change trim types, click the relevant button. The Batten button displays available batten materials for that line style, offering several options including None (no material), Custom (fabricated flashing profile from press break), regular flashing items (roll-former fabricated), or Flashing Assembly (multiple flashing profiles for parapet caps and box gutters).
Important: All materials must first be defined using Set-Up > Flashing.
🔧 Wall Battens Configuration
The wall batten button includes the Insert/Modify option that opens a comprehensive setup dialogue for wall battens/purlins.
Batten Spacing Options
Setting | Description |
Top/Bottom Spacing | Pre-set spacing near wall top and bottom for building code compliance (cyclonic/hurricane areas) |
Left/Right Spacing | Pre-set spacing near wall sides for code requirements |
Intermediate Spacing | Fixed spacing or evenly spaced along wall length up to maximum spacing |
Additional Battens | Extra battens around openings and wall top/bottom |
Batten Division and Management
For portal frame commercial structures, battens/purlins may need splitting at wall frames. Use the Divide at Wall Frame Line option to specify which frame member divides the battens. You can divide individual battens or all battens using Divide All at Wall Frame Line.
Button | Function |
Merge Batten Line | Fixes incorrectly divided battens |
Delete Batten Line | Completely removes batten/purlin from model |
Apply All | Applies battens/purlins using defined spacing settings |
Delete All | Removes all battens/purlins from model |
Delete | Removes selected battens only |
Apply Selected | Applies battens to specific wall with current settings |
Continue | Returns to Flashing dialogue to continue trim setup |
Change Batten | Switches to different batten material |
Save Spacings | Saves current settings for different wall systems |

🧾 Wall Flashing Allowances
Click Allowance to display the allowances dialogue box.
These allowances work similarly to roof flashings and rely on wall directions (inside/outside) and connections to determine internal or external flashing line configurations.
⚠️ Important: Allowances are not automatically applied for walls drawn individually or flat. Use the Single-Allow button to modify flashing allowance lengths manually.
Allowance Type | Description |
Run Allowance | Length added to each line to ensure adequate installation material |
Lap Allowance | Length added for lap joins in material |
Internal Allowance | Extra material for creating mitred internal corners |
External Allowance | Extra material for creating mitred external corners |
