Plan oblique and isometric 25/10/16

There are many different projection techniques that you can use to represent your interior, building or object, such as:

  1. Multiview drawings– plans, elevations and sections.
  2. Paraline drawings– plan oblique, elevation oblique and isometric, axonometric.
  3. Perspective drawings– 1 point perspective, 2 point perspective and 3 point perspective.

Plan oblique

  • They are drawn using a 45 degree set square or a 30/60 degree set square.
  • The area in the middle is always 90 degrees.
  • The plan of the room can be used as a base.


Firstly, we were given measuremeants for a plan we had to draw with the scale ruler with 1:50.


Then I had to make it into a plan oblique drawing so on a 180 degree line I drawn another line that was 45 degrees high and 4000m long, then went on to the opposite side to draw another line that was 45 degrees high and 4000m long.

After, I set the plan under the piece of paper and drawn the plan out again but on a 45 degree slant to the same measurements as accurately as possible.


I then done the exact same again but with one side 30 degrees and the other side 60 degrees.


Isometric

  • They are drawn using a 30/ 60 degree set square with just the 30 degree end.

  • The area in the middle is always higher than 90 degrees.


Starting off on a 180 degree line each line is then drawn 30 degrees high and 4000m long and then a vertical line is drawn straight up the middle. From the end of the line you have to draw another line that is 4000m until it reaches the vertical line in the middle. Then do the same on the other side.

On this one, the plan can’t be placed underneath because it is a different size so you have to figure out the objects inside using the scale ruler.


Self directed work:

Draw a plan oblique drawing of your halls of residence or home bedroom.

I measured up and drawn my bedroom from home.
