Columns on the above table :
point - the points ( A , B , etc.) in the above parametric point map are a few examples of reference points.
position on left end plane - entries to this column on the table describe (in words) the position where a particular point (A or B or etc.) is placed on the left end plane of a "toe in" channel beam.
mem.left.location + mem.trans_to_global(X,Y,Z) - an expression similar to this one is automatically entered to the " Point 1 " and " Point 2 " fields of the parametric material window that appears when you Add Material operation. The expression "mem.left.location" is the left end work point of the member. The operation "+ mem.trans_to_global(X,Y,Z)" defines individual X, Y and Z member coordinate distances and adds those distances to the member's left end work point in order to define a new point in global coordinates .
X is the X member coordinate distance from the left end member work point (mem.left.location) where the new point generated by the parametric will be placed. As illustrated above , a positive X distance translates the point away from the left end work point of the beam (the beam's 0,0,0 point ) and toward the right end, whereas a negative X distance translates the point in the opposite direction.
Y is the Y member coordinate distance from the left end member work point (mem.left.location) where the new point generated by the parametric will be placed. As illustrated above , a positive Y distance places the point above the top flange of the beam, whereas a negative Y distance places the point below the top flange.
Z is the Z member coordinate distance from the left end member work point (mem.left.location) where the new point generated by the parametric will be placed. As illustrated above , for a "toe in" channel beam a positive Z distance translates the point away from the heel of the channel and in the direction that the channel toes point, whereas a negative Z distance places the point on the far side of the beam workline (off of the material).
