Divide the number of ceiling tiles in 1/2 and put aneven number on both sides.The count from our wall is 12, so there is six tiles oneach side of the center mark.Mark each tile at an inch or a half inch, they are a halfinch in this demonstration.
See the left and right top ceiling corners?The ﬁrst and last tiles are at the corner of theroom you are drawing. The ﬁrst and last markbecome the spot where you draw the vertical lines to make the side walls for your room
Close up of where the vertical line starts for the side wall,meeting at the top left corner.
This part is tricky, you have to use artist observation toﬁnd the ﬂoor line... you have to look at the shape of thewall you chose and decide where the ﬂoor line goes.Make sure it matches the shape of the wall you arelooking at.
Begin the orthogonal lines that make up the lines for theceiling tiles that go from the back of the room over yourhead
The line originates from the vanishing point, goes thoughthe mark on the ceiling line and extends to the edge ofthe paper.
Complete those steps for all the marks you made forceiling tiles across the ceiling line of your drawing.
Draw the “helper” line that will help to make the ceilingtiles look like they get smaller as they go back in space.Start it at the back right corner at about a 40 degreeangle.
Each time the “helper” line intersects with one of theceiling orthogonal lines that is where you place your rulerto make the horizontal line that makes up the ceiling tilesgoing from left to right of the room.
The ﬁrst horizontal line would start where the small arrow is, but for the demo you can see the second one better.Rest the ruler on the intersection, make sure it lines upwith the ceiling line and is perfectly horizontal.
Keep making horizontal lines though the intersections.
Compete the lines to the very top of your paper.
Take a look at the left wall, any line that appears tohorizontal is going to be drawn as an orthogonal. All ofthe vertical lines will stay vertical.
Drawing the column in the corner. start with theline on the left wall that goes from the ceiling lineto the ﬂoor line.
Make that ﬁrst line into a rectangle.Continue by making a horizontal line comeour from the top and bottom of the ﬁrstline you drew.
Use your artist observation todetermine how wide thatcolumn should be.
The second vertical line that makes the rectangle mustcomplete the rectangle by closing it off at the top andbottom.
Find the right side of the rectangle by drawing orthogonallines from the top and bottom right of the rectangle.
Connect the orthogonal lineswith a vertical line that goesfrom the top of the back wallto the bottom.
