Continuing the above, I do have several plugins I find I use frequently.
TIG’s Mirror plugin - invaluable for constructions with symmetry
TIG Weld, to link together separate line and/or arc segments
A construction point plugin (PointTool)
A construction line plugin (CB_Cline)
Steve Baumgartner’s Angular Dimension (an improved version is nearing beta testing)
Stair Maker
Xref Manager - to update pieces of scenery in the set model, when the elements are changed in a separate construction drawing. (you can also just Import them, but Xref Manager is more versatile, especially if you have multiple component copies).
Several of Fredo’s plugins - Round Corner, particularly.
A plugin I developed myself to insert and label flats and rostra of different standard or custom sizes, and standard curtains and curtain legs.
Not a plugin, but equally useful and time saving:
Dynamic components (DCs) I’ve adapted to draw Steeldeck rostra, with support legs, at different heights
DC to build a staircase
DC Scaffolding fittings, and an adaptation of PipeAlongPath, to help draw scaffolding structures, which we have used on several sets.
Most of these are also of general use for set construction design - scenery or props items we build in our workshop (staffed entirely by volunteer woodworkers).
