1. Imported supplier files
In this example, the supplier provides a version of the required part, which is imported as an IGES file. Our intention is to modify this part in Solidworks rather than rebuild it. To do this, we will create a version of the model that matches the new part specification directly from the existing geometry.
- Open supplier file
The red arrows point to the tabs that need to be flipped vertically on the +Y axis. The tab needs to extend 0.75" in the +Z direction to match the new part.

2. Split the part into multiple entities
To start modifying the part, we need to create cuts through the part. First, add a reference plane (image 2) parallel to the outer surface of the tab (highlighted) and coincident with the part's vertex or tangent edge.
Figure 2: Creating reference planes from parts
Next, separate the single subject into two separate entities using the segmentation feature (Figure 3 and Figure 4).
The reference plane we generated in the previous step is used as the cutting plane for the split feature. And, as you can see, the single part has been split into two bodies. (Figure 5)
Figure 3: The split function is located under "Insert > Split function" >

Now that the part has been split into two bodies, the next step is to reorient the bodies to the desired location. To do this, use the Move/Copy command via Move/Copy > Insert > Function (Fig. 6).
Figure 6: Move/Copy Function Location
Think of Move/Copy features as Component Mates, but for multibody parts. First select the subject to move. (Highlighted in Figure 7) Select both faces for the coincident mate. Right click on the top face of the second body, use Select Other and pick the bottom face of the part. (If the orientation of the body is not as expected, use the Mate Alignment option to flip the orientation of the entity). Click Add to create additional mates (do not click OK to close the function at this time).
Figure 7: Adding the first mate to orient the entities
Now that the body is oriented correctly on the +Y axis, add a distance mate between the faces of the body. (Picture 8) The desired distance is 0.75". Click Add to add one more pairing to the feature.

The final step in the Move/Copy feature is to add a coincident mate between the tangent edge or surface and the outer plane of the second body. (Fig. 9) Click OK when ready.

3. Convert the multibody part back to one solid
Now that the two entities are in the correct orientation and position, we need to fill the space left between them in order to have one entity again. (Fig.10) For this we will use a simple Boss - Protrusion feature.
Figure 10: Multibody part to be reconnected as a single body
The Convert Solid tool in the Command Manager Sketch tab is used to create a sketch on one of the faces. (Fig. 11) The Convert Entities command creates a sketch on the edge of the part with the Sketch on Edge relationship in place to fully define the sketch.
Figure 11: Sketch > Convert Entities
Using the Boss Extrude feature, use the new sketch created in Figure 11. Change the "End Condition" to "Up to Surface" and select the mating face of the second body (Fig.12). Note that the "Merge Results" checkbox should be selected at this point.

4. Part files that have been modified
As shown in Figure 13, in a few simple steps, parts can be modified without converting imported solids to SOLIDWORKS features.
