Printing Northeast 3d view to scale

[crubadue]

Hello to all.

I assume that the default 3D view (no perspective and not a camera) and using the Northeast preset view under View, Orient is an isometric drawing. Lines that are paralleI to the isometric the three axes should measure true length or scale. So, to test it I made a simple 4 30'x10' walls. Then under View Properties I set the View Scale to 1/8" =1'-0". When we print the 3d view our 30'-0" wall measures 24'-6" at 1/8" scale. Our printed 2d views measure correctly. I have tested this on three printers (HP and Epson) and a (OCE)plotter. I am simply are at a loss trying to get the 3d view to measure correctly even after checking and testing the following:

View Scale is 1/8"
Print each type of Print Range
Printed from the view and a sheet.
Zoom 100% (not scaled to fit)
Paper Placement


This is not 100% accurate but the work around I have at the moment is:

Set the print settings Zoom, Scale to 122%.

Are other people getting the 3d view to measure correctly without this kind of work around? Any insight would be appreciated!

Regards,

Corey

Are you placing the 3d view on a sheet & then plotting? Or are you plotting directly from the view?

I have tried both methods and I get the same result.

I guess I might not be sure what you mean when you say lines parallel to the axis should measure true scale.

Can you post a screenshot showing the view & what lines you expect to scale or measure true?

Attached should be an Isometric and a plan view. The dimension you see on each view should measure the dimension shown at the scale you have selected for your View Scale.

I don't think there's any way you can do it.

You could place the sheet on a drawing, then if you wanted it a 1/8 scale, draw two 30° lines 3-3/4" apart. Then activate the view, set the scale to custom, and adjust it up & down until you get the corners to approximate the endpoints of the 3-3/4" lines.

All the Revit docs refer to these views as perspective views. You'll notice that when you place the view on a sheet, even though the view scale in properties reports out at 1/8" per foot, it does not carry over to the scale label on your drawing sheet.

Not sure how the scale parameter ended up on 3d views, but it sure does confuse...

@andrewg,

Thanks for your feedback.

Maybe I am missing something...Maybe there is a bug and it should work...Maybe it simply doesn't work. It's funny, it is just so darn close. The printed drawing measures 25'-6" at 1/8" scale. That is only 4'-6" (about 1/2") away from being at 1/8" scale. It appears as though the view scale should work. When you change the scale value the drawing size also changes. In fact I printed out 1/4" and 1/8" scale views and compared the difference in the drawing being printed to scale. They both are off by about 118%.So, if you print only from the 3d view itself you can "fix" the scale by using the zoom by% print setting.

== Scale the Print by 118%.
30'/25.5'=1.1764 round up to 1.18

== get percentage
1.18 *100= 118%

The method you suggest should work equally as well for printing from sheet views.

Further to this discussion, As you render the View and capture the Image within the project, you will notice that the image has a scale either 1:1 or 1:10. You don't have any control over this and even if you try to change the scale to anything else, the image doesn't seem to change.

Can someone explain the scale involved in the Rendered image?

Has anyone seen anything other then 2D construction drawings produced with Revit? I would really like to see some examples if so...

What do you mean "other than 2d" I've seen perspectives, renderings, colored floor plans, as well as 2d construction documents all done in revit.

[crubadue]

I mean axonometric, isometric, or sectional perspective drawings that are used to explain technical construction information. I have only seen 2D sections and elevations used to explain construction information and shaded renderings of the 3d model for visualization purposes from Revit.
