custom shapes using polygons:<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p>
<ol style='margin-top:0in' start=1 type=1>
<li class=MsoNormal style='color:navy;mso-list:l0 level1 lfo1'><font size=2
color=navy face=Arial><span style='font-size:10.0pt;font-family:Arial'>Imagine
you are standing outside of the building looking squarely at the surface.
Your first point (0,0) will be at the bottom left hand corner – this
corner will eventually correspond to the floor polygon vertex that anchors
your custom shape to the rest of the building. <o:p></o:p></span></font></li>
<li class=MsoNormal style='color:navy;mso-list:l0 level1 lfo1'><font size=2
color=navy face=Arial><span style='font-size:10.0pt;font-family:Arial'>Now
enter the coordinates for each additional point as you travel counter-clockwise
around the shape. All of the coordinate values will be expressed in terms
of how far away they are from the first point, (0,0), and the actual
surface (not the dimension indicated in plan views). You will need to use
dusty geometry skills to convert plan dimensions, specifically: Cosine =
Adjacent / Hypotenuse. You want to solve for the hypotenuse and you get
the adjacent length from plan view dimensions; measure the angle of roof
tilt with a protractor on the exterior elevations or building cross
sections.<o:p></o:p></span></font></li>
<li class=MsoNormal style='color:navy;mso-list:l0 level1 lfo1'><font size=2
color=navy face=Arial><span style='font-size:10.0pt;font-family:Arial'>Now
that you have a polygon, use it to make an exterior wall. Under “Location
& Geometry”, set the Location as the vertex of the parent space
polygon that is located closest to the (0,0) point of the new child
surface polygon. <o:p></o:p></span></font></li>
<li class=MsoNormal style='color:navy;mso-list:l0 level1 lfo1'><font size=2
color=navy face=Arial><span style='font-size:10.0pt;font-family:Arial'>For
non-square walls, the Tilt will be 90° and there is likely to not be a reason
to change the X, Y, or Z offsets or the Azimuth. All of these offsets are
relative to the vertex of the parent space polygon that anchors the child
polygon. Changing the X offset moves the child surface along the plane
defined by the parent polygon anchor point and the next parent polygon
point (counter-clockwise as viewed from above). Changing the Y offset
moves the child surface along a plane that is normal to the X offset. The
azimuth of the child polygon is the angle between the lower edge of the
child polygon relative to the wall defined by the parent polygon anchor
vertex.<o:p></o:p></span></font></li>
<li class=MsoNormal style='color:navy;mso-list:l0 level1 lfo1'><font size=2
color=navy face=Arial><span style='font-size:10.0pt;font-family:Arial'>For
simple sloped roofs with no eaves, change the Z offset to be the height of
the vertical walls, leave the Azimuth at 0, and make the Tilt the angle of
pitch relative to horizontal. <o:p></o:p></span></font></li>
<li class=MsoNormal style='color:navy;mso-list:l0 level1 lfo1'><font size=2
color=navy face=Arial><span style='font-size:10.0pt;font-family:Arial'>If
a sloped roof has eaves, then the X and Y offsets need to be changed to be
sure that the (0,0) point of the child polygon is located the correct
distance from the parent space polygon anchor vertex. The Z offset will probably
need to be slightly shorter than the height of the wall. <o:p></o:p></span></font></li>
