Walls > Modify Wall Panels
🧾 What it does
This command allows you to modify how panels have been generated on walls. You can adjust join overlaps, split panels at specific locations, merge panels together, delete unwanted panels, change lengths, and realign panels with different reference lines.
🔧 How to access
Click on Modify Wall Panels to open the modification dialog where you can access all panel editing options.
🛠 Splitting panels
Option | Description |
Join Underlap | Enter the amount you require panels to overlap at joins |
Use Maximum Panel Length Only | Any panel lengths exceeding the Maximum Panel Length will be automatically split at this length |
Select Panel Split Line | Manually select a line where you want to split panels (e.g. window edge, door edge, wall purlin). Useful for panels cut to length or supplied in factory stock lengths |
Split into Stock Lengths | Automatically selects appropriate sizes from defined stock lengths (Setup > Metal Panels). You can choose to display actual length or rounded up length matching stock sizes |
🛠 Inserting panels
Insert Cladding Panels: Generate panels on a single wall plane at a time.
🛠 Merging panels
Merge 2 Panels: Merge two panels together to create one panel.
🛠 Deleting panels
Option | Description |
Delete Individual Panels | Manually select panels to delete one at a time |
Delete All Panels on Wall | Delete all panels on a selected wall plane |
🛠 Modifying existing panels
Option | Description |
Change Panel Length | Individually modify calculated sheet/panel lengths. Usually done after site measure where small changes are needed due to construction variations. Specify amount to add or subtract from panel length |
Realign Wall Panels | Align panels with any line in the model geometry, door/window edges, or custom reference lines |
🧾 Panel alignment options
The default starting point for each wall has panels aligned with the wall corner. However, you can align panels with any line in the model geometry.
Creating custom alignment lines:
Create a line using CAD > Line Insert > Vertical Length
Snap the start point to the apex (line length doesn't matter)
Align panels with that line to align with the highest point of the wall
Copying existing lines for alignment:
Use Smartlines > Copy Line function
Copy the line to the required location (snapping to the desired point)
Align panels through the new location (e.g. ridge apex of gable end)
Delete the copied line if it has attributes to avoid adding to quantities
🛠 Alignment examples
Door edge alignment: Align panels with door edges for consistent appearance around openings.
Random line alignment with stock lengths: Align with custom lines and divide into stock length panels for optimal material usage.
💡 Tips
If you don't get the desired result, simply use Undo and try a different approach
Consider panel alignment early in your design process to minimise later modifications
Use stock length splitting when working with pre-cut panels to optimise material usage
Remember to delete copied reference lines with attributes to avoid quantity errors
⚠️ Important notes
Panel modifications affect material quantities - review totals after changes
Some modifications may require regenerating adjacent panels for consistency
Always verify panel lengths meet structural and installation requirements
