What is A GEOMETRIC CONSTRAINT IN CAD?
Finally, Autodesk add parametric features in AutoCAD 2010. Why finally? This feature is already there in manufacturing industry for decades. If you have used any manufacturing application like Inventor, CATIA, SolidWorks, ProE, etc, then you should be already familiar with this feature.
Geometric constraints associate geometric objects together, or specify a fixed location or angle.

AutoCAD can apply geometric constraints to 2D geometry. Two objects are constrained to each other in a specific way. Objects can have more than on constraint. For example, if a square is drawn, all four sides must be equal in length and each leg is perpendicular to another.
AutoCAD 2011 significantly simplifies the process of adding geometric constraints to 2D AutoCAD geometry. AutoCAD can infer geometric constraints as you create and modify geometry. A new Infer Constraint button on the status bar enables you to toggle inferred constraints...

In Inventor you can make the sketch geometry behave in predictable ways by using geometric constraints and parametric dimensions. ... Teaching them AutoCAD is an entirely different workflow, and mindset. Constraints in AutoCAD will help with this an aweful lot. Workflow:
AutoCAD 2010 introduced a great new feature, parametric constraints. You can constraint objects in two ways:
Geometric constraints associate geometric objects together, or specify a fixed location or angle. For example, you can specify that a line should always be perpendicular to another one, that an arc and a circle should always remain concentric, or ...
Topics covered in this Lesson: Parametric Constraints: This is a new feature in AutoCAD 2010. Parametric constraints allow you to force an object to behave the way you want it to.
Best Answer: There are many in the toolbar to the left. The geometric constraints available are making objects perpendicular, parallel, tangent, equal, horizontally and vertically alligned, and many others. You can adjust any of these constraints by going to the origins folder and ...

1. What is a geometric constraint? A Geometric constraint is a Constant, non-numerical relationship between the parts of a geometric figure.
Geometric Constraints. Geometric constraints can be defined among solid elements inside a Boolean tree, or among entire solids in 3D space. If constraints are defined inside a Boolean tree (inside a solid created from multiple elements), they allow you to fix a position of a particular element.

Geometric Constraint ... Previous GSoC projects have made progress towards a parametrics/constraint library. Please check libpc Developer Doc as well as the libpc source. For this year's project, we're suggesting a specific direction as outlined below. BRL-CAD does not presently provide the ...
Last week, I wrote, in Solving the CAD concurrency problem, about 2D geometric constraint solvers. Solvers are one of the major components used in 3D CAD programs, and are the main part of the sketcher used in parametric feature (history based) modelers.
Parametric Drawing Parametric drawing provides precision and productivity. You have greater control to enforce design intent, and may very quickly modify a design by using geometric and dimensional constraints.
Dealing with engineering or CAD, a geometric constraint deals with constraints such as parallel or perpendicularity. A numeric constraint deals with distances and size.
