Vectorworks Spotlight – Drawing in 3D. Beginners guide to starting out in 3D. Follows the six On Stage Lighting 2D Vectorworks Spotlight tutorials that get you started that can be found at http://www.onstagelighting.co.uk/training-tutorials/vectorworks-spotlight-tutorial/
This tutorial is a first step into working in three dimensions and shows you how to create a 3D model in Vectorworks Spotlight from a basic 2D theatre groundplan of poly lines using Extrude. Topics include:
The difference between 2D and 3D draughting
The benefits of 3D modelling in CAD
How technical drawings are created from a 3D model
Different working views in Vectorworks
Screen Plane Vs Layer Plane
Creating a 3D object from a 2D shape using Extrude
Creating a venue model using Extrude with a closed polyline
Boolean operation: Cutting out doorways using Subtract Surface
Setting object height in 3D space and using Vectorworks as a calculator
Creating a complex 3D object using Add Solids
** Note: Make sure you follow good 2D line housekeeping before building solids from them. It’s best if your polylines are closed properly or multiple lines are welded together to create a single line. This will ensure you model geometry is true and avoid problems later on.
Update: As noted in the Comments, this video introduces basic 3D modelling from 2D lines using Extrude, Add and Subtract Solids. The next step is to understand AEC Wall and Door objects alluded to in the video, so that you can harness their power for venue/scenic creation.
