This article provides Best Practices and Tips for Duct Extraction and Alignment using EdgeWise. Refer to the full ducting guides for the full workflow. If EdgeWise is still struggling to perform duct extraction and alignment in your project, then refer to the tips below.

Tip 1

Perform the initial duct extraction in an area with good point cloud coverage. Try drawing the extraction box to capture two sides of the Duct, preferably the depth and width.

Tip 2

Use the Set to Selected tool after selecting a duct to set the size of the extraction tool. By doing this, the algorithm now knows the size and doesn’t have to choose based on the catalog. To revert this change, use the A hotkey to set the size back to Auto fit.

Tip 3

After extracting multiple ducts, select all the ducts in a run and use the snapping: aligned tool. This tool will rotate the ducts on the center line so the corners will match up, making the connections come in seamlessly.

Tip 4

If a duct becomes disconnected from the chain while editing, the snapping: Reconnect tool allows for the duct to be attached back on. Simply select the duct and then select the duct it will attach to. Use the tab key to see all the ducts in the connected chain.
