I am having a problem with my sketches. They become skewed after adding smart dimensions to them. What could be the problem? See attached pictures.
I figured out the problem. I needed to check the automatic relations box in the system options under relations/snaps settings.
Phong, you need to add relations to your sketch. Click on the dimension and in the property manager on the left choose to add horizontal, vertical, perpendicular or what ever the relation which fits the need is.
First of all, orient yourself to the sketch plane and then make sure the edges opposite of each other are at least parallel (vertical or horizontal, too) and then i should work better.
You need to add Geometric Constraints (examples: vert, horz, parallel, perpendicular) as well as Dimensional Constraints.
