How accurately do the eaves have to be drawn?
The eaves widths used by the program are determined from the distance between the external wall and the roof line. The eaves width must be drawn as accurately as possible when modelling the shading of windows This is not so critical when shading walls. When you draw the roof line the eaves width should be made the distance between the outside of the window glass and the outside edge of the roof gutter. 34 I’m having trouble inserting a window into a wall that is just off vertical (with respect to the plan). This problem, (which also occurs with doors) only occurs if the external wall is slightly off vertical. If this is deliberate, draw the wall as being vertical, insert the door or window, then move the wall node to give the required angle. If the “off vertical” is not deliberate, use a snap greater than 100 mm, ie 250 mm. You should select to constrain the drawing movement to the horizontal and vertical and only remove the constraint when drawing walls that don’t meet at right angles
