Geometric feature shows centroid instead of centre when modelling frame origin of STEP file

I was running MATLAB 2019b and currently doing some Tutorial to the Simscape Multibody module. However, when I tried to model my frame origin based on the geometric feature from STEP file, I have gotten the centroid instead of center, as shown in figure below.

Is there any way to change the geometric feature from centroid to centre instead, as it is needed to model the revolute joint in the future?

Hi Lai Chung Kwan,

If the geometric feature you have selected doesn't pick the location you want, you can pick another one.

Whether or not the center or centroid is selected depends on the type of surface you have picked. If the feature (curve, surface) has an easily identifiable center, then "center" will be selected. If not, then "centroid" will be selected. See the screenshots below.

Thanks,
