*'''OP_Line''' – creates a floor using two points each with x, y, z, and width values drawn perpendicular to the line created by the two points. This is essentially an angled ''AddFloor''. Also, the function does not use OP_Draw.
	Syntax: <code>OP_Line(destobject, name, texture, aligntexturemap, x1, y1, z1, w1, x2, y2, z2, w2)</code>

''destobject'' specifies the destination object (floor, external, buildings, landscape, or elevator). name is the name of the object. ''texture'' is the texture of the object. ''aligntexturemap'' currently does nothing. ''x1, y1'', and ''z1'' correspond to the x, y, and z coordinates of the first point. ''w1'' is the width of the floor at the first point. Likewise, ''x2, y2, z2'', and ''w2'' correspond to the x, y, z, and width values at the second point.
<!-- Figure 1 -->

The width is always drawn to the right 90° from the direction of drawing. In other words, when travelling down the line from P<sub>1</sub> to P<sub>2</sub>, the width will always draw to your right. 
* from –z to the +z direction, width will draw towards the +x direction
* from +z to the –z direction, width will draw towards the –x direction
* from –x to the +x direction, width will draw towards the –z direction
* from +x to the –x direction, width will draw towards the +z direction

<!--You may use these non-trigonometric formulas to obtain the other two points of the floor. These were derived using similar triangle properties.

x-coordinate of Qnx =Pnx + (w_n*(z2-z1))/√(〖(x2-x1)〗^2+〖(z2-z1)〗^2 )
z-coordinate of Qnz = Pnz – (w_n*(x2-x1))/√(〖(x2-x1)〗^2+〖(z2-z1)〗^2 ) -->

'''OP_MultiLine''' – creates a path of connected floors using multiple points. This is useful in making curving 3D objects such as curved railings, roads, or track. Currently, MultiLine is limited to a '''maximum of 7 points'''. Like OP_Line, the function also does not use OP_Draw.

Syntax: <code>OP_MultiLine(drawingmethod, destobject, name, texture, tilex, tilez, numberofpoints, x1, y1, z1, w1, x2, y2, z2, w2, x3, y3, z3, w3...)</code>

''drawingmethod'' does nothing. ''destobject'' specifies the destination object (floor, external, buildings, landscape, or elevator). name is the name of the object. ''texture'' is the texture of the object. ''tilex'' and ''tilez'' are the texture tiling values. ''numberofpoints'' specifies the number of points in the multiline (maximum is 7). ''xn, yn'', and ''zn'' correspond to the x, y, and z coordinates of point n. ''wn'' is the width or the line at point n.

Similar to Line, the width is always drawn to the right 90° from the direction of drawing. In other words, when travelling down the line from P<sub>1</sub> to P<sub>2</sub>, the width will always draw to your right. 
* from –z to the +z direction, width will draw towards the +x direction
* from +z to the –z direction, width will draw towards the –x direction
* from –x to the +x direction, width will draw towards the –z direction
* from +x to the –x direction, width will draw towards the +z direction

MultiLine uses a set of special non-trigonometric formulas to calculate the points Q<sub>n</sub> in the '''Figure 2'''. These were mathematically derived using similar triangle and vector bisector properties.
<!--	'''''Endpoints'''''
x-coordinate of Qnx = xn + (w_n*(z2-z1))/√(〖(x2-x1)〗^2+〖(z2-z1)〗^2 )
z-coordinate of Qnz = zn – (w_n*(x2-x1))/√(〖(x2-x1)〗^2+〖(z2-z1)〗^2 )

'''''Intermediate Points'''''
x-coordinate of Qnx = xn – (d_1*w_n*((x_n-x_(n-1))/(-d_1 )+(x_(n+1)-x_n)/d_2 ))/((x_n-x_(n-1))((z_n-z_(n-1))/(-d_1 )+(z_(n+1)-z_n)/d_2 )-(z_n-z_(n-1))((x_n-x_(n-1))/(-d_1 )+(x_(n+1)-x_n)/d_2 ))
z-coordinate of Qnz = zn – (d_1*w_n*((z_n-z_(n-1))/(-d_1 )+(z_(n+1)-z_n)/d_2 ))/((x_n-x_(n-1))((z_n-z_(n-1))/(-d_1 )+(z_(n+1)-z_n)/d_2 )-(z_n-z_(n-1))((x_n-x_(n-1))/(-d_1 )+(x_(n+1)-x_n)/d_2 ))

where d1 = √(〖(x_n-x_(n-1))〗^2+〖(z_n-z_(n-1))〗^2 ) and d2 = √(〖(x_(n+1)-x_n)〗^2+〖(z_(n+1)-z_n)〗^2 ) -->

'''OP_Polygon''' – creates a regular polygon (equal side lengths) with an arbitrary number of sides. Current restrictions include a '''maximum of 10 sides'''. The polygons are drawn to be inscribed in a circle (see '''Figure 3'''). The function also doesn't use OP_Draw.

Syntax: <code>OP_Polygon(drawingmethod, destobject, name, texture, numberofsides, centerx, centerz, radius, altitude)</code>

''drawingmethod'' was created to allow the polygon to be drawn as if it were circumscribed about a circle, however this function was discontinued for OP_AdvPolygon and was only programmed to do inscribed polygons. ''destobject'' specifies the destination object (floor, external, buildings, landscape, or elevator). ''name'' is the name of the polygon object. ''texture'' is the texture of the object. ''numberofsides'' specifies the number of sides the polygon will have (current maximum is 10). ''centerx'' and ''centerz'' are the respective x, and z coordinates of the center of the polygon. radius specifies the distance from the center to the vertices when inscribed or the distance from the center to the midpoint of each side when circumscribed.

Currently, the polygon will always draw starting at the +x direction from the center (x = ''centerx'' + ''radius'', z = ''centerz''). A ''rotation'' parameter will be added later to allow rotating the polygon at an arbitrary angle counterclockwise from the +x axis.
