Add-onsAdd-on for CadCraft
HVAC
HVAC ductwork: duct runs drawn on a centerline with their elbows, transitions and branch fittings, a double-line plan and solids on the 3D tab from the same run, equal-friction sizing from airflow, and a duct schedule with sheet metal area that goes to TakeoffCraft.
What it is allowed to do
- Adds commands
- Adds toolbar buttons and menu items
- Adds a panel section
- Adds settings
- Adds its own objects and data to drawings
- Opens or saves its own file types
An add-on runs inside the app with the app's own access to the page. That is why only add-ons the CadCraft team has read, reviewed and signed can be added from here; the apps check the signature again before they load one.
Add
Adding needs JavaScript in this browser. You can still download the signed package.
Add-ons you added work in the browser apps on this computer, offline too. They load when the app starts: reload an open app after adding one. Turn one off any time in the app's Settings, under General. The desktop app will add from here too; that is not built yet.
