Lofting a 2 point perspective drawing from orthographic side and front views Locate a side and front view of a simple house – we found a nice modular design at ecodesign.co.uk. On a tracing paper overlay, draw a consistent grid.
Extrapolate what you believe to be a logical top view. In this case, I referred to an available axiomatic view from the same site to understand the design of the upper window casements.
Don’t go into details like deck boards, just establish basic position points, like the chimney, edges of the deck, peak of the roof, etc. In this case we have those special windows cut into the roof.
Presentation Format Create a presentation format as shown here with a simple border line. Create downsized grids and position top, side, and front view, to leave room for the projected 3d view to come. Once the orthographic views are done with grids, copy them to smaller sized grids and lay them out like this. We will be lofting the 3D view in the large open space.
Draw in a horizon line about one half the height of the page. The next step will determine the basic size of the house, as well as the extremity of the perspective. We want the space to be filled nicely, without either the front or the side to recede back too sharply. The footprint of the house needs to be determined, as well as the height. Take some time planning out this important step. You might need to try more than one scenario to determine what is best for your design. Here I determined that the horizon line in the center will work best. Alternatively, you can try it one third from the top or one third from the bottom. You might need to tape an extra sheet of paper to your drawing to extend one of the vanishing points.
Guesstimate the height of the grid and lay in some vanishing point lines.
What we are making is the grid-box first, then the house will be drawn on that grid. Since we know the grid is 4 squares high, divide the vertical edge line by 4 and draw vanishing point lines:
Side Using the box dividing method, start to build the boxes that recede into the distance to the left:
Foundation Next is what we call a “judgment” in which we determine by eye what is a reasonable-looking square tile on a plane receding:
This shows the side and the foundation:
Add the front in a similar manner:
You will help your cause of visualizing in 3 dimensions if you also layer the “draw-through” sides – the back side, and the rear of the house. Using paper Do this with either colored pencils, or, layer using tracing paper hinged with tape.
Shown with the side included:
Now add the back in gray:
Add the top in green:
Altogether now:
Now we can screen that all back and draw on the top. In pencil Take your heaviest erasable black pencil, and draw over the colored lines, or better yet, draw on tracing paper, or better than that even, use a marker and draw on vellum or translucent marker paper, or, a sheet of sketch paper on a light box. Also at this point you can consider which direction you want you house to face. I decided to turn mine 180 degrees, so the porch faces right. Note the change in position of the side and top view ortho drawings. This shows placing the foundation lines in black.
Continue with finding whatever major elements you can easily identify and draw its location in the 3 dimensional grid ... here is the side facing us:
Now the roof; then the front; make guidelines wherever you need to, in order to determine position in 3D space:
After very major shapes are determined, you proceed to creating details, using the grid to help position windows, chimney, doors, etc. Add shrubs, trees, terrain, bricks or wood, etc:
Finally, cleanup for final presentation, and and lettering. Do the lettering 1/8 inch high. House design title
Lastly, add textures for wood, etc. |
