Drawing Tools
Photopia’s CAD system includes several drawing tools that can be used either as
reference geometry to help the construction or manipulation of other entities or as
geometry that directly participates in the optical analysis. The drawing tools provided are:
Arc – you can construct an arc by specifying 3 points along its curve or by
specifying its center point and the included angle. If you specify the included
angle with the mouse, the angle is assumed to be positive and thus always
sweeps counter clockwise. You can enter a negative angle and the arc will
sweep clockwise. Arcs are always constructed in the XY plane of the view’s
coordinate system.
Circle – you must specify the center point and radius of the circle. Circles are
always constructed in the XY plane of the view’s coordinate system.
ß Illuminance Plane – you can quickly draw an illuminance plane in the CPlane by
specifying the lower left hand corner and the upper right hand corner of the
rectangle. You can also specify the grid name, and column and row settings.
Line – you can specify a series of points and a series of individual line segments
will be created. Lines can be defined by any arbitrary 3D endpoints.
Polygon – created by specifying 3 vertices that can have any arbitrary 3D
location.
