Overview of how RogCAD works:

The following data entry in RogCAD's
preformatted editing area produces a simple house:

              min      max
             x,y,z   x, y, z    

AUTOCUBE40:  0,0,0   20,30,8     (a cubic shape)

STANDARD:                        
1   10,0,12                      (the two points defining 
2   10,30,12                      the peak of the roof)

LINEG1:                          (the lines connecting the 
1,2  1,408  1,402  2,406  2,404   roof peak points to each
                                  other and to the cube)     





This pavillion was generated by a user typing the 
following numbers into RogCAD's preformatted editing area:

First, define a string of autocubes for the
left hand beams and for the horizontal beams:

    x1  y1  z1        x6  y6  z6    spacing   endcube   rot,col
         
AUTOCUBE00:  
    0  -10  0        .3  -9  6.75     7         8       0,6
       
AUTOCUBE20:    
    0   -8  6.75     .3   0  7.75     7        28       0,6

AUTOCUBE40:
    0   -6  8.1       0   6  8.75     7        48       0,6


Next, skew and tilt the autocubes
to their proper shape and position:
first    last    tranx  trany  tranz
202    358      0     -1     -.75
208    358      0     -1     -.75
204    354      0      0     5.25
206    356      0      0     5.25
203    353      0      0     5.25
205    355      0      0     5.25

402    552      0      1      0
408    558      0      1      0
404    554      0     -1      0
406    556      0     -1      0

    2    152      0      1     .25
    8    158      0      1     .25
    4    154      0      1     0
    6    156      0      1     0
Rotate a copy of the left hand beams 
to create a mirror image:
 first  last   zangle   tranx trany tranz
  1     358     180      56.3   0    0

Define vertices of the roof sections:
STANDARD:
1    0,-9,7
2    56.3,-9,7
3    0,0,13
4    56.3,0,13
5    0,9,7
6    14,9,7
7    28,0,13

Define the perimeter lines of the roof sections:
LINEG1:
1,2   3,4     5,6     6,7

Define the planes for the roof sections:
AUTOPLANE:
1    1,2,3,4  
2    5,6,3,7

are the x and y radius, the z offset and the

Artwork assistant
Let RogCAD get your perspective right before you 
do your artwork.

You can use RogCAD in its most basic form (see first
example on this page) to provide yourself with a simple 
perspectively correct wireframe model of your object, 
which you can then print out and paint over with your 
water colors.

Just a few minutes of assigning xyz coordinate values 
for the key vertices of your structure, then "connecting 
the dots" with RogCAD's line assignment routine will 
result in a simple rotatable wireframe model, with an
unlimited number of camera realistic perspective 
options.
