Control which panels manual dimensioning snaps to

Choose which panel types manual dimensioning snaps to in elevations by selecting them in the 'Enable panels for manual dimensioning' setting.

1. The 'Enable panels for manual dimensioning' setting in the elevation preferences applies only to the panel types selected there.

2. Manual dimensioning snaps to the panel types selected in the 'Enable panels for manual dimensioning' setting only.

3. Leaving just one panel type selected makes manual dimensioning pick only that panel.
