Panel editing

When panel support exists for the selected car, Builder can treat named regions as selectable surfaces. You can select one panel, drag a marquee across multiple panels, or use size filtering to find small panels.

This is meant to reduce template hunting. Instead of manually finding every vent, tab, grille piece, or trim part, you can select the relevant regions and apply a consistent fill.

The panel-size selector highlights panels under a chosen pixel-area threshold. It is intentionally aimed at small values because tiny panels are the ones that are hardest to locate and easiest to miss.

A massive panel matching a high threshold is not the target use case. The useful case is quickly finding small parts so they can be filled, checked, or excluded from a broader design pass.

• Tiny thresholds help locate small trim and detail pieces.
• Medium thresholds can catch secondary body pieces without grabbing the main body.
• The selected panels feed the same fill workflow as normal selection.

Multi-select and size-based selection are working selections. They are not saved groups, named folders, or permanent classifications inside the project.

That keeps the project model simpler: select the panels you need, apply the change, then cancel or replace the selection when you move to the next task.
