In the conceptual modelling environment, if you have a trapezoidal face that isn’t a perfect square or rectangle, when you divide this flat surface the resulting grid will be applied at an assumed rotation, aligning itself to the angled edge. 9 times out of 10 this is not the result you were looking for.
It would be really nice if the grid was distorted so that it divided all of the edges equally resulting in a more uniform grid arrangement. Just like the image below.
How do we get to this result?
Well as it happens the conceptual environment seems to favour distorted, organic forms. So just pick the point at the top corner of the face and distort it ever so slightly.
In this instance I am adding .0001 to the dimension. Technically it isn’t perfectly flat anymore but dimensioning will round it to the correct value, and nobody will ever know. It is your little secret.
