Creating TRUE axonometric drawings in Revit

[Anonymous]

Hi there first time poster here so if this is in the wrong section then please accept my apologies.

I'm wondering if it's possible to create a true 45,45,90 degree axonometric in Revit Architecture 2011?

I've searched and searched and no answer, only a solution for an Isometric view which on certain sites is described as an Axo. If any of you guys know if this is possible then please reply with the solution, it's driving me mad!!!!

I'm willing to export to other programs such as AutoCad too if this eases the workload, however at the minute it's looking likely I will be hand drawing the Axo!!!!

are you trying to draft an axon in a drafting view, or just set a 3D view to an axonometric?

The final drawing produced has to be an axonometric, how this is achieved is irrelevant.

I have beeen trying to do this in a 3D view,, not sure how I would go about it in a drafting view?

Bit of a long shot but try this.

1. Draw an object which has a plane which faces the direction you want to view from - so, say draw a roof which has a 45 degree pitch.

2. Change to a 3D view - not a camera view as thats perspective.

3. Right click on the view cube, and select "Orient to a Plane...", in the dialog box that appears select "Pick a plane".

4. Select the plane which you want to view from - say the roof (you can then delete the roof).

Any good??

That will work in terms of producing the 45 degrees need but won't the vertical lengths be shortened?

Hence it's not a true Axo. I know this is extremely pedantic but the idea of the axo is to be able to scale from all 3 dimensions.

I would have thought Revit would have this ability built in, if not it definitely should!! lol

Is it a school assignment? If so, it was obviously meant to be drawn by hand-I don't know of ANY 3D computer program that would do that. All I know of are only capable of projections where the picture plane is perpendicular to the projecting rays, and not oblique views. What you are asking for is a "plan oblique", true axonometrics always had a foreshortening factor that was used in scaling the verticals (or the depth, in case of elevation obliques) to make it look more realistic. They really do not have any practical purpose since computers went 3D. Their existence was based on that they were easier to construct by hand than perspectives. Axos and isos look ugly to laymen, so communication today is almost exclusively with 2D drawings and perspective views.

The other way to approximate it is to make a perspective view with the smallest possible camera angle, but setting it up i not a very trivial task. Someone made a plugin for SketchUp for that, but it's not 100% accurate either.

i know this post is a little old, but i too found this very frustrating that revit doesn't do a "true" axo. revit is a tool for architects/engineers etc, yes ? ...and when have they not wanted to do a drawing to scale ? (apart from perspectives of course)... mad!

on a somewhat more positive note...

Autodesk Ecotect will do a "true" axo in its 3D Editor tab. Not in the Visualise tab (as that is done using OpenGL just like revit and other 3D tools), but in the 3D Editor tab it draws the axo the proper hand drawn way, thus scalable in both axis.

FormZ will do a true Axonometric.

Google Sketchup does axo views.

Rhino does Axos

Old post, but it came up when I was trying to find this out. It is possible to create an axonometric view using the technique found at http://wrw.is/color-fill-legend-in-a-3d-view-and-see-rooms-in-3d-in-revit/, note this doesn't give a true scale z-axis but the x and y are true. Plus it is possible to use colour fills!
