🧾 What Sub-Figures are
Sub-Figures are CAD entities that have been grouped together and can be managed as a single item. This is particularly useful in roofing projects where you need to place multiple identical components.
For example, if you have multiple solar panels to install on a roof, you can draw them in 3D and then group them into a Sub-Figure. This allows you to place all the solar panels as a single item rather than positioning each component individually.
AppliCad uses this process extensively with Fixtures - pre-built components like vents, skylights, solar panels and other roofing accessories. Refer to the section about Fixtures for more detail.
🔧 Sub-Figure menu options
The Sub-Figure menu provides three main functions:
Function | Description |
Open... | Opens an existing sub-figure from your Database. Browse and select previously saved sub-figures to use in your current project. |
Save As... | Saves the currently selected CAD entities as a sub-figure into your Database. This creates a reusable component for future projects. |
Merge | Merges an existing sub-figure into your current model. The sub-figure components become part of your active drawing. |
🛠 How to use Sub-Figures
To create a Sub-Figure: Model the item in 3D, select the CAD entities that comprise the unit you want to group, then use Save As... to save them as a reusable component - eg SolarPanelx6 or SolarPanelx10 etc
To use an existing Sub-Figure: Use Open... to browse your saved sub-figures and select the one you need
To add Sub-Figure content to your model: Use Merge to incorporate a sub-figure's components into your current drawing or;
Add them as a Fixture (refer to that section for more details on creating Fixtures)
💡 Practical applications in roofing
Sub-Figures are ideal for:
Grouping fixtures or equipment
Creating custom vents, solar panels or skylight assemblies
Standardising complex flashing details
Building libraries of commonly used roofing components
⚠️ Important notes
Sub-Figures work with the Database system to store and retrieve your grouped components. Make sure you have appropriate database access when saving or opening sub-figures.
