constraints in solid modeling

M

ost solid modelers support 'geometric constraints'

. A

geometric constraint is the relationship of  an entity to other  entities

onstraints are only used on the underlying sketch or  wireframe entities that define the solid o

b

ounaries

. S

ome common 'constraints' for  these entities are coincident, collinear, intersect,  parallel,  perpendicular, and tangent

. W

hen one or  more entities are 'constrained' to each other, changing any of  the entities will most likely ha

v

e an effect on the others

In the example , the lines and arcs ha
