I've been making these with the workaround for a few years when detailing a balloon drawing of small objects within a very large enclosure. I'm wondering if there's an easier way to do it.

I want an Isometric view derived from a section view, so that the Isometric View shows half of the assembly cut away. Here, I show that I inserted a plan view (1), defined its section view (2), then tried projecting it as an isometric (3). You see that the isometric view then ignores the section cut.

A workaround I've used has been to Cut-Extrude through everything in the Assembly (i.e. Assembly Feature) within a sub-configuration for this purpose. Then I repeat that to show the other half. Then I insert my desired (custom or) Isometric View and select the section-cut configuration.

Is there an easier way to achieve this without using an Assembly Feature Cut-Extrude?
