You can define constraints for a set of vertexes of a 2D creation profile. Vertexes can be constrained relative to another vertex or to the center of the coordinate system. You can also define radius of circles or arcs as a parametric value.
The vertexes are endpoints of lines, circle centers, intersections of lines or arcs (in case of filleting or blending) or interpolation points of NURBS curves.
Parameters can be used in definition of distances between vertexes, or as a value of radii, for instance.
Parameters and constraints defined for vertexes
To define constraints and parameters within a solid’s creation profile, first select a solid for editing. Then switch 2D edit mode to constraints definition – click the corresponding icon in the edit toolbar.
Selection of a method of constraining
You can select a method of constraining and then select vertexes, or select vertex or vertexes first and then select a constraint. Vertexes can be selected individually by clicking them or by selection window (rectangular area).
Selection of vertexes for constraint definition. Selected vertexes will be constrained to the coordinate center at a distance.
Reference point is defined. The constrained distance will be distance between the coordinate center and the selected reference point.
Distance is defined. Instead of a constant value, a new parameter named “length” is created. In the following step, a numeric value will be assigned to this parameter.
In this example, the circle center is constrained at X direction to the selected vertex (marked with the anchor).
After distance definition, the circle is moved. Distance from the center to anchoring point was defined shorter than the previous distance.
