Paul,

I have to agree with Sandeep - an article is not practical other than to convey how powerful a tool this is.

Isogen is the one of the primary reasons most of the 3D plant design products exist.

The power in the plant design system is being able to easily make changes to the line and then produce a piping isometric automatically in seconds which requires no manual markups.

If configured properly (and it takes some experience to do this) you can achieve this BUT you must also drive the 3D software properly - garbage in, garbage out.

140+ Isogen attributes with 2-10 options per attribute

80+ additional Isogen attributes for PDS with 2-10 options per attribute

Hundreds of additional configuration items in the Isogen config files.

Most 3D Plant Design tools are now delivering sample Isogen setups which can be used immediately but I doubt they would ever be sufficient to cover all the variables in any project - these setups would definitely result in having to manually modify the iso.

As for defaults - with this stuff there is really no such thing - if you want no manual annotations you have to configure it to give you exactly what you want in the format you want. You can literally control everything including sheet breaks, scale of graphics, weld data, fonts, colors ...

This is also the problem for most companies - with the ability to do so much customization you also have the potential to mess things up very easily, sometimes it may not be apparent until someone does a proper iso check. You also need to vigorously test the configuration prior to extracting for issue.

Biggest job I have configured resulted in 17,000+ ISO's issued in 6 months with no manual markups on any of them.

3D modelers can take shortcuts, fail to
ensure connectivity, not keep fabrication/iso breaks in mind while modeling, etc., which will sometimes cause iso fun downstream. Can't really blame the modelers, as it's very difficult to be detail perfect when doing general routing tasks.

Poor design is poor design - no matter how it is done.

Once again - Thanks Paul - hope this is all starting to finally pay off for you.

I also hope that one day we can work together on a project somewhere - this stuff really shines IF you use it right.

Writing a article is a good idea, but it will take some time as there are
some 140 attributes to be configured and hundreds of other things. In the mean time you can have a look at the sample isometrics generated by
ISOGEN. The sample attached are purly automatic and no manual editing is

done. Even the attributes are imported from Line-list.

Perhaps I have only seen poorly-extracted isometrics then, and some of them are acceptable. But others are absolutely ridiculous (too bad I can't provide an example - I'll see if I can find one next week).

Care to provide some tips on generating decent isos outputted by Isogen?

I don't think I've ever seen a write-up on this and if you want to write

a short article I'll feature it at the website.

Paul
