Axonometric projections such as isometric renders are possible for Arch Visualization using Maxwell Render Studio (MXST).

You could also render **Building Elevations*** by adjusting the camera height (up/down- approx. 5'8" height from ground line) for example! [See upcoming tutorial with instructions on setting up an Orthrographic projection]

Scene Setup:

1 - Load a scene with camera and objects set for nice perspective render.

2 - Write down the Maxwell Camera film width and film height settings.

3 - Multiply the camera film and height settings by 0.5. Put these settings into the film width and height settings for the camera.

4 - Increase focal distance until your object is again centered in view.

5 - Keep reducing camera film width and film height by 0.5 consecutively and increasing your focal distance until you reach a single digit number.

6 - To set final camera film width and height, multiply .001 times the original value you started with in step 2. Set the camera film width and height to the final values given by the factor above.

7 - Increase focal distance again until your scene is position where you want it for the orthrographic rendering.

8 - Done - Render!

Explanation:

Perspective views are normally established by a set of vanishing points where parallel perspective lines are allowed to converge to these points. In conventional rendering and drawing, this can be defined as one, two or 3 point perspective.

What is happening with the settings above is that the parallel lines that define a perspective are not being allowed to converge. In orthrographic projection (architectural elevation) drawings such as top, left, right, left, bottom, and axonometric), the vanishing points do not converge.

I have used this technique in Arch Viz production and it works for very nice building elevation (orthrographic) renders!

BONUS TIP!

If you are using Sketchup, all you have to do is set the field of view for the scene to zero prior to exporting the scene to MXS. Once FOV is set, make sure you re-position your scene into view then export to MXS.
