Structural drawings typically include beam section sizes (and cambers and studs) and reactions, depending on your corporate standards. Like Revit, Voxel Link allows you to show any and all of those tags using your corporate standard tags. 

Start and end reaction tags are placed using a fixed inset from the beam end (3.0 * textHeight). Section tags are centered on the beam span. To work well with Revit's capability to rotate Crops, it is best to have the horizontal justification for the reaction and section tags to be center-justified so each text rotates about its center.

If the reaction tags are left or right justified, the Keep Readable parameter on the tag text rotates about those justification point and the text ends up overlapping with the supporting member. This is native Revit behavior.

All three tags should also be center justified vertically so they appear the same distance from the beam whether they are placed above or below the beam line.
