Applying Constraints
Constraints are the restrictions applied to the degree of freedom of a free object. Applying specific types of constraints to elements enables you to conveniently and successfully model a complex geometry.
Constraint tools let you fix various dimensions that control the location and/or orientation of elements on a profile, and also let you fix geometric components relative to each other, so that they remain correctly located even if the underlying geometry or feature is modified.
- Dimensional -
Dimensional Constraints define the exact dimensions of a construction. Using
the dimensional 2D constraints tools, you can constrain Length of an Element,
Distance between two points, Angle between two line segments, distance between
three or more coplanar line segment - making them equal, area of a closed
profile, and perimeter of a profile.
These operations provide you with great potential of controlling the dimensions in your design and hence let you achieve your intent of modeling complex geometries eventually.
- Geometric -
Geometric Constraints are non-numerical relationships between the parts of
geometric figures which controls the shape of the profile.
Using the geometric constraining tools, you can constrain the different components of an elements to be parallel, perpendicular, coincident, concentric, tangent, fixed and equal.
