When trying to define grid lines rotated about an axis I am having problems defining the grid lines by clicking on elements within the model. For example in the below image I select the first node of the bar as the "relative point". I then create a grid line A and grid line 1 by clicking the first node of the bar and get grid lines that pass through this node. However when I click the node at the end of the beam I don't get grid lines that pass through the node. I was working on a model earlier where this problem was not occurring so I know it is possible to resolve this I just don't know how.
Any help much appreciated
