Previous Week Recap

We will be discussing this more in section as we hand back drawings from last week. Reminder: for final review, no elevations are required. Only plan and section drawings.

Upcoming Review

We will be going over setting up presentation boards later in the semester, during Week 12. If you are having trouble organizing your drawings and managing your file size, feel free to browse the following workflows:

Quick tips + guidelines: (pending your Instructor's advice)

  • All plans + sections should match up and coordinate
  • Keep text minimal and small (12 pt or less, no fancy headers)
  • Keep drawings balanced - not too spaced out, not too tight fighting
  • TEST PRINT! Print out sections of your board to check lineweights and poche to make sure they do not print too light or too dark
  • PRINT EARLY + GET SLEEP - this cannot be emphasized enough.

Axonometric + Analytic Drawing

Last week, we practiced orthographic drawings such as plan and section that describe the formal attributes of your double negative. For your final review, you must also provide a three dimensional analytic drawing of your model. In additional to describe the spatial qualities of your final model, this would aspire to describe your overall concept. This could be expressed in terms of your tectonic method, the final model in relationship to the original voided forms, or the formal composition in relationship to your montage.

Axonometric Drawings provide the advantage of representing a form in 3d without any perspective - therefor still being a measured drawing. The drawing is constructed from a plan that can be rotated 30, 45 or 60 degrees. With the advent of 3d modeling programs, it has become much more common to see different rotations or complex views that are not so typical in traditional hand-drafted axon drawings. Exploded drawings , which the same view is replicated with different compositions of the form or building, representing different relationships and connections. All of these can be easy to produce by controlling the Viewport and attributing proper lineweights after using the Make2d command. Additional analytical drawings could include serial axons, exploded perspective drawings or interior perspectives, to name a few.

  • Examples : Double Negative

  • Viewports
    • Controlling the viewport allows you to create 3d drawings in the form of perspective and paraline drawings. Check out this tool link to learn the following:
      • Setting up Views
      • Saving Views
      • Creating Linework from these Views
  • Axonometric Lineweights

In axonometric, the conventional order of lineweight hierarchy is as follows:

  1. Edges or boundary of the form (either edges along the outside of the object and the background as well as edges of an object protruding in space)
  2. Planar corners (two or more surfaces touching each other and creating an edge)
  3. Surfaces lines or details (no change in form)


Workflow - Creating an Axonometric Drawing
This workflow will show the steps to produce an axonometric drawing using an existing digital model. The final drawing will be composed of both linework that has edited and cleaned-up on top of a simple rendered image of the digital model.


This is the Exercise .

This file should be printed out at 8.5" x 11" and turned into a bin on the 6th + 7th floor elevator lobby (right outside of studio). Your name and your GSI's name should be located on the lower right hand corner of this print out.

All final submissions are due no later than 5:00 pm on Friday, September 14th.
