Hi Tony, so I guess you just want to model the basic curved outline of the shoulder pad?

I'm still not entirely sure if I understand, but if you want to construct a block with a curved outline in MoI then the way you would do that is to run the Draw curve > Freeform > Control points command here:



Then go to the Front view, and draw a profile curve that has the shape you want, something like this for example:



Then you can construct a solid block from that profile curve by selecting it and running the Construct > Extrude command here:



That will produce a result like this:




In order to make a good match with your shoulder pad you will probably want to take a picture of it from straight above and then place that image into MoI as a background image so that you can see it in the viewport and use it as a tracing guide when you are drawing the curve.

To place a background image you use the View > Image command, as shown here:

Please let me know if I still did not understand what you are trying to do.
