Notice that the designated constraint is listed in the window in the top part of the dialog.This listing window uses the same interactive expand/collapse operations (and othersymbols) as is used in the Assembly Navigator.SelectApplyto accept the constraint.More About: Align ConstraintUse the Align constraintwhen one geometric entity lies everywhere on the other.Example:By everywhere, we mean that an align constraint is solved using unbounded geometry, so thegeometric entities do not have to actually touch to be aligned.1) Align constraint uses unbounded geometry.
140Usage Matrix: AlignAssigning Mating ConditionsDefining a Mate ConstraintNext, apply a constraint that will keep the back, flat face of the spacer mated with thestepped shoulder face on the shaft.Choose theMateiconfrom the Mating Conditions dialog.Select theFilterpulldown and choose theFaceoption (if necessary).Select the inside, flat face of the spacer.Again, notice that the TO iconis automatically activated.Select the flat shoulder face of the shaft.
141This time preview how the intended mating constraint will act. The Preview function letsyou see the intended mating before you actually apply the constraint.ChoosePreview.Again, the designated constraint is listed in the window in the top part of the dialog.The spacer should be allowed to rotate on the shaft, so these two components are matedsufficiently.SelectApplyto accept the constraint.More About: Mate ConstraintUse the Mate constraintwhen you want to mate objects of components with opposingnormals and want to define a physical contact between two entities.
1421) Selected ("from") face on the base component2) Selected ("to") face on the mated componentUsage Matrix: Mate.Assigning Mating ConditionsMating the Caster-ForkNext, you will apply some constraints to the caster_fork in relation to the caster_shaft and thecaster_spacer.Again, you will be using the mating constraints:AlignMateFirst, Align the cylindrical hole face of the fork with the shaft.
143Choose theAligniconmating condition.Select theFilterpulldown and choose theFaceoption (if necessary).Select the cylindrical hole face of the fork. Use the select options cursor/box to aidselection, if necessary.Select the stepped cylindrical face of the shaft.ChooseApplyto accept your mating operation.Next, Mate the back face of the fork to the outward face of the spacer.Choose theMateiconfrom the Mating Conditions dialog.Select the back side face of the fork.Select the outside face of the spacer.
144Remember, you can use Preview to check the result of your mating operation before youactually accept it.ChooseApplyto accept your mating operation.Your successful solution should look like the illustration below.
