Now, let’s create the necessary dimensions on the drawing. Dimensions are created on a sketch in the same
way as on a parametric drawing. One can select graphic lines instead of construction lines in this case. Let’s
skip the detailed description of this functionality, as it was described in depth as part of the main drawing
technique.
This completes creation of the non-parametric drawing. Further modification of its elements will not affect
the whole drawing. One would have to modify each view separately. The elements of such a drawing cannot
be related by variables. All other functionalities such as use of visibility levels, layers, hide/show
construction entities, etc. are fully supported.
Creating a parametric drawing in the automatic parameterization mode
We will use the same drawing as an example. The sequence of constructions will be the same as described in
the previous section of this chapter.
When working in the automatic parameterization mode, we will be creating only graphic lines (as when
constructing a sketch). Meanwhile, the system will be automatically "slipping" nodes and construction lines
with parametric relations underneath those graphic lines. What constructions to create and what
dependencies to use in relations is determined by the system based on the user-selected snaps and parameters
defined in the command's property window when creating sketched lines.
Call the command “SK: Create Sketch”. Make sure that the following snaps are enabled:
