Integrating modified areas in existing design data
Several changes were manually implemented in this die. Now we have digitized the die and imported it into the CAD model. The distance analysis using function "Design / Analyse / Compare" shows the points where the original design data and the mesh data differ (red areas). What is the easiest way to now combine the changes with the original design data?
Meshes can be quickly and easily converted to surfaces and integrated in existing design data using the Tebis BRep functions.
Here's how you do it
In this example, we will only examine the geometry-relevant areas in the middle of the component. Select function "BRep / Top / Create." Since the design mesh and the scanned mesh are different, select option "Topology and reference differ".
Confirm your inputs. The BRep topology is generated.
In function "Configure facets," delete the surfaces you want to replace with new ones based on the scanned mesh.
Create the new surfaces. The scanned mesh is used as the reference. For example, use functions "BRep / Face / Approx" and "BRep / Surf / Approx". The reverse-engineered surfaces are shown in red in our example.
Now export the BRep surfaces with function "BRep / Top / Export".
The modified areas are transferred to the existing design data set as CAD surfaces.
Hints
For detailed information on reverse engineering with Tebis Brep modules, call up the context-sensitive help for module switch "BRep" in the "Module" menu.
