Drawing in the Conceptual Design Environment
When you access the conceptual design environment, you can immediately start to draw a concept in 3D.
Select a drawing tool, such as a line, and click anywhere in the drawing area to start creating a form. (See
Forms on page 551.)
NOTE To draw in a 2D view, open it from the Project Browser.
Drawing Overview
You draw when you are placing lines and points to create a form. You can draw on the following elements:
■ surfaces (See Drawing on a Planar Surface on page 534.)
■ 3D levels (See 3D Levels on page 536.)
■ 3D reference planes (See 3D Reference Planes on page 539.)
■
reference points (See Hosted Points on page 541.)
3D levels and 3D reference planes are automatically detected. They highlight in the drawing area as the
cursor moves over them. Click to select one of these to set it as the active work plane.

3D Snapping
Use 3D snapping to ensure an exact location for placing points on a model vertex. For example, you can
use 3D snapping to help place a surface on a mass that you can later use in the project as a floor or a roof.
To enable 3D snapping, select 3D Snapping on the Options Bar.
To create a surface using 3D snapping
1 Create 2 forms. (See Forms on page 551.)
