Piping Isometric Drawings

MadoreJacob — Sat, 07 Oct 2023 23:32:44 GMT

Hey guys,

Trying to find the best way to create Isometric drawings in Revit for piping (single line drawing that a fabricator can use) and I downloaded Ez-ISO, but their manual sends me to a dead end.

I follow the steps and the Ez-ISO manual shows a "Data" tab in the Revit properties palette, see below:

However, this "Data" tab is nonexistent in Revit when I select a pipe. What am I doing wrong? Ultimately, when "Run" Ez-ISO it gives me the following:

The "Go to ISO-Viewer [0]" button is greyed out, how do I proceed?

I am open to using another Autodesk software to make these iso's...

Cheers!

i don't believe EZ-ISO is an Autodesk product. I'd recommend contacting the developer (HuenSystem) for support.

What sort of information are you trying to present to a fabricator in single-line format? Size? Length? Fitting Type?

Trying to piece together what you're looking to do that isn't ordinarily covered via Annotation Tags.

Essentially, I want an iso view to look like this, a true isometric view
for piping (which also needs to be submitted for approval by our governing
body).

My bad, let's try again.

Basically a single line drawing with c/c distances, etc.

Most of what is shown there can be automated just by freezing a 3D view in place and applying Annotation Tags.

Where you might get into some deviations in drawing standards would be the run lengths, since those are displayed as dimensions in your example.

I believe you can get dimensions in 3D views to work with piping but it's a pretty manual process unless you know how to work Dynamo. If permitted, you can opt to include pipe length in your tags instead. It just won't have the framing lines.

Notes regarding elevation can be done with spot elevation tags. Keynote items with keynotes. Generic text with....generic text.

Flow arrows are tricky due to how Revit handles left/up and right/down in tag orientations, and tag-on-placement tends to mess up the center alignment of arrow shapes. I'd look into getting a Dynamo script for this.

With the exception of the flow arrows (they would need to be placed separately) you should be able to do that in native Revit. You may need to edit some of your families to display correctly in single line mode.

I didn't realize there was a single line mode? I've done piping 3D views with the actual pipe shapes and I don't like the way it turns out.

How do I go about activating single line mode?

Switch the view to Coarse mode. This will turn piping to single line.

If you are using manufacturer fitting/accessory families, you may need detail line-based annotations in coarse view. Some families will already have this, others won't. So you might wind up with a hybrid of single line and then fully rendered control valve, unless you do it yourself.

...actually you may just want to do it yourself anyway so that the detail line representation is consistent to your company standards.

Did you find any answer, I need to submit my drawings to governing body and this Revit is not being useful. I can annotate in coarse mode but is there any other way ?

Revit does not do true isometric views. They need to be generated separately from the actual model view unless you can manipulate your 3D view to something acceptable. It would be helpful if you could show us what you have and an example of what you need. Also, include what you have been able to accomplish towards this end goal.

I’m a bit late to this party but have you tried the PIPEEX PCF plug-in? It isn’t from Autodesk I think but works great with Revit and is easy to use.

No, I haven't but I'll surely check it out! Thanks!

I use 3d views and filter out anything i don't want to show. i also do that for HVAC. For better clarity i often use two 3D views from opposing view locations.

I know it is not truly isometric, but it is the real system and changes if you make changes.
