zDimArea dimensions the area of closed planar curves, faces, Breps and meshes. It draws a 45 degree hatch at the center of each object to mark it.

Quick start

Run zDimArea.
Pick closed and planar curves, or any face, Brep or mesh.
Adjust the TEXT group.
Mark commits the dimensions. Cancel discards them.

TEXT

A row at the top has three presets, Tiny, Small and Large Object. The preset affects only Text Size. This tool has no arrows, so the only group box is TEXT.

Unit Format: the area unit format.
Text Size: the height of the dimension text.
Decimal Places: the number of decimals in the area value.

How the settings work together

A change to any of the three fields recalculates everything. A preset switch affects only Text Size.
The text direction no longer follows the world XY axes. The tool works out the smallest-area bounding box of each object and aligns the text to the long side of the shape itself, so it is no longer always horizontal.
Circles are the exception. If the picked object is a circle (or a closed curve that reduces to a circle), the text still follows the world axes, because a circle has no clear long side and aligning to it would make the text direction jitter between nearly identical circles.

Input requirements

Curves must be closed and planar. Curves that are not cannot be selected, because the picker filters them out. Faces, Breps and meshes have no extra limits.

Good to know

The HUD at the top right shows the total area live, so you do not have to add it up.
Every area label comes with a 45 degree hatch, shown together with the area text.
If you close the dialog without pressing Mark, the tool removes its empty layer. After Mark, all the dimensions (hatch included) are put in one group.
This tool also closes its dialog with Ctrl+Z (the same as zDimVolume. The other zDim tools do not have this shortcut).
