Concept of drawing rules

 Buttons to convert the tab to grey scale or to black and white

 Standard buttons – new, insert, copy, delete

 Buttons moving the selected row up or down – important for specification of higher priority of the rule

 

Drawing rules can be specified for lines (hatches, filled polygons) and for Automatic labels.

Drawing rules define how parts of the structure will be projected on the section plane. The user can specify a predefined set of conditions (columns) and then specify how the lines matching the condition will be displayed (pen colour, thickness, hatching, colour of filling) or labelled.

The dialogue for drawing rules is similar to the dialogue for palette setting. The concepts of drawing rules for lines and labels are:

1.  the priority of rules is based on the order of  the list (with exception for the same rule for back, section or front position of the projection)
2.  the more general the rule is the lower priority it should have: (see example b)

Example a)

Such drawing style will project contours of concrete columns as red lines, contours of all other elements will be displayed as black line.

Example b)

Such drawing style will project all elements as black lines because the first row has higher priority than the second one. This would be more-likely the mistake in drawing style specification because nothing will be generated by the second drawing rule.

Example c)

Such drawing style will project all contours of structure parts as black lines and then centre lines of all columns will be generated as red line. In this case the order of rules is not important as the rules are for different element parts and therefore are independent. The same projection will be displayed by a drawing rule with reverse order.

Exception for Back, Front and Section in the same type of rule – see Advanced tips.

Example d)

Example e)

This drawing rule will project contours of the whole structure as black lines without any exception.
