Problem description

#13525 introduced the great new smart dimension tool but also the individual area dimension tool. The former works perfectly but the latter fails the first time it's applied. Steps to reproduce:

1. Add Part Cube.
2. Add TechDraw view of the cube.
3. Select the face and apply the Area Dimension (not the old Area Annotation).

It shows 0 mm^2 and the following error message:

<Exception> getGeomTypeFromName - empty geometry name

Just retrying should make it work then.

Btw. do we still need the area annotation? If yes, these 2 tools should have different icons:
