Inventor – Horizontal and Vertical Constraints


We all know about constraints.  It make the world go round. 

I have a reasonable amount of twisted workarounds, but very little every day constructive examples.  So, I as thinking of AU (as ALWAYS) and was reminded of Dan Banach drilling productivity tips at us, and Horizontal and Vertical constraints were mentioned numerous times (seriously, take his class at AU).

Whether you are in training or didn’t pay attention to this feature, you should consider it.

This Horizontal constraint should be applied to geometry that passes through the horizontal plane from another reference feature. Refer to the image below.  I’d like the sketched geometry to be evenly distributed across this part.  The best way is with constraints.


Right Click the background to bring up the cursor menu, select Create Constraints, and pick Horizontal.  


Position the cursor over the mid point of the geometry to be constrained and you should see the mid point snap appear. 


Pick the snap glyph, and then hover over the midpoint of the reference geometry, and again select the mid point snap glyph. 


The new feature will align it’s midpoint to the horizontal plane passing through the reference (for all you folks from down here in the south, that means it “centers it evenly”).  


Repeat the same process to apply a Vertical constraint.  Use this on the top or bottom the the feature.  In the example below you should be able to see the snaps as they are being applied. 


Now the part is distributed evenly AND constrained, so no matter the changes, this sketched feature will adapt.


In this example, it is dimensioned to be 1/3 width, and 1/3 height, and constrained to adapt to the part changes.

To quote Dan, “Inventor Rocks!”
