[Equest-users] Tilted roof?

[Ryan Schmidt]

In order to make a tilted roof in DD mode, change the tilt angle of the
roof surface. Depending on the vectors used to define the polygon and
surface, the axis of tilt may be right or wrong. If it is wrong, try the
following steps:

 

1)       create a copy of the polygon used to define the roof surface

2)       change the azimuth of the roof surface

3)       modify signs (-/+) and invert x and y components of new polygon
in order to relocate roof

4)       Note the distance from the axis of rotation of the building
origin and the desired axis of rotation on the roof surface and use this
displacement to reposition the roof. Delta elevation will be SIN of the
tilt angle times this displacement. The lateral displacement will be
(1-COS of the tilt angle) times the displacement.

 

Once the tilted roof surface is created, new triangular external wall
sections can be created to fill in the gaps. I apologize if this
explanation is unclear.

Subject: [Equest-users] Tilted roof?

 

Is there a way in the eQuest DD Wizard to make a full tilted roof?  I
know there is a way to make a pitched roof, but that seems more geared
towards residential applications as they don't give you much flexibility
in tailoring it to your custom project.  I'm sure there is a way in the
Detailed Edit mode but in my first few attempts at that all my polygons
went crazy.  This is the type of tilted roof I want to model (section
view) that is tilted on the south orientation for PV panels:

 

 

 

Any help would be great...thanks.
