A dialog box will open to navigate to and directly open the model.

If the geometry is correct and does not require any editing, the import process is complete and analysis can begin However, if there are any errors with the geometry, there is excessive or invalid detail, or if its not organized into separate bodies conducive for electromagnetic analysis, you may soon realize that the editing capability is limited to scaling, reorienting, or Boolean operations.

This approach can be particularly troublesome when portions of the model (or all of the model) which consist of different materials are not split into different objects.

For example, notice the outer conductor, inner conductor, and dielectric of the imported SMA below are all one solid object.

The good news is, the process described above will continue to work.

The better news is, SCDM offers new capabilities to directly edit or clean imported geometry.

So, here are a few simple steps to quickly split this SMA connector using SCDM.

If you need access to SCDM, you can contact us at infopadtinc.com.

Its worth noting, at this point, that the processes discussed throughout this article work the same for HFSS-IE, Q3D, and Maxwell designs as well.

Hold the Ctrl key and click the center mouse button to pan, and use the center mouse scroll to zoom in and out.

Finally, press z on the keyboard to fit the view window.

When positioned, click on the object to split (in this case it is the entire model).

Then, click on the face which defines the boundary between the dielectric and outer conductor.

Finally, press the Esc key.

Notice under the structure tree that there are now three separate objects.

Reposition the connector to view the female side.

Control the visibility of each body with the objects checkbox in the structure tree.

Measure the length of the female side by pressing the letter e on the keyboard and selecting the top edge (note the line length of 2.95mm for later).

Then, repeat the Split Body process to split the center conductor at the boundary between the male and female sides.

However, rather than pressing the Esc key, click on the female receiver to automatically remove the body.

Perhaps the most familiar approach to HFSS users would be to save the new model as a STEP file, then to import the model into HFSS as described in the first paragraph.
