Use Copy to Construction to verify or repair imported data with errors. Copy to Construction duplicates a base feature (either a surface or solid) in the construction environment, where you can use special commands to analyze and make repairs. You can then redefine the feature in the part environment to replace the old data with the repaired data.
You can use this procedure to update a part model with changes made to a base feature generated by IGES, STEP, or SAT.
Note: By default, Autodesk Inventor applies the part name (file name of the inserted part) to browser file nodes, whereas other CAD systems may apply the part number property. When a STEP file is imported into Autodesk Inventor, its name may differ from the name of the CAD system which generated the STEP file. To avoid confusion, use Rename Browser Nodes to specify the browser node naming scheme.
- Open a STEP, SAT, or IGES file. A base feature is created in the part browser.
- Right-click the base feature, and select Copy to Construction. A duplicate feature is created in the construction environment.
- In the part environment, right-click the base feature, and select Suppress Features. The construction copy is still visible.
- In the browser, double-click the Construction folder to enter the construction environment. Click to expand the construction groups. The copy has the same group name as the base feature name in the part environment.
- Use commands on the Construction tab to analyze and repair data errors.
- Right-click the Construction folder, and select Finish Construction.
- In the part environment, two bodies are now visible, with one overlaid on the other. Right-click the suppressed base feature, and select Unsuppress Features.
- Right-click the base feature, and select Redefine. The base feature is redefined using the repaired construction data.
The construction copy is consumed by the redefined feature, but the group remains in the construction browser.
