Isometrics - Multiple Line Numbers on 1 Iso sheet

[JoeKay]

I'm having issues with the Isometrics. The 'De-Mystifying' instruction weren't any help either. I'm trying to get as much info and lines on one Iso sheet.

For Example I have a main High Pressure gas line with a 2in by pass. Both have separate line numbers. I need both of these lines to show up on one Iso sheet. Now I know I wont get everything on 1 sheet but at least need the by passes (with different line numbers) to be on one ISO sheet together.

Any insight to this would be greatly appreciated. Thanks.

You cannot do this with Production Iso.  Quick Iso will allow you to combine multiple line numbers into one sheet.

Now are you talking selection by windowing the lines? Cause that didn't work and ends up with all the line labels as 'Userdefinedline'. I did select multiple lines check marked. Then Advanced Options and made sure ISO split was off by line number. Still no avail. Also speaking on that, the Override splitting is always check marked, even if its not set in the ISO options to be that way. I have to unselect it everytime. Could this be causing an issue, if so how do I get it to no be checked?

The check mark is not the root of the issue. By design the software will not drop multiple line numbers on one production iso.  The only workaround is a quick iso. Unfortunately, it is true you lose all line group tagging and attributes dependent on line group properties.

So fubar is the word I'm probably looking for. You'd think there would be and option to show by-passes with different line numbers. I mean that's the point of Isometrics. Isos and Spool sheets are 2 different things but yet the program treats them as the same. Thanks again for your help as always Jabo.

Historically isometric generation has been focused on spool (or spool-like) drawings where you have one and only one line number per drawing.  There hasn't been much development in system-type isometrics which allow for multiple connected lines, or single or multiple disconnected lines.  Could be a legacy of the PCF format.

I think there are some very good opportunities for work in these areas.

Which I understand. But I'm trying to cut sheets down from 500 to 75-100. If I have to ISO every line number, plus those usually get cut into 2 or 3 sheets, I'm going to end up with a huge number that has to be checked and manually edited.

Just on a side note, why does the bypass have a different line number? Is it a different Spec?

[JoeKay]

Different line, size, path. Client Specifications. That's how I've done it and always seen it.

Interesting... thanks 🙂

The volume of checking and editing doesn't change that much.  There's just more on each drawing to go through, so each drawing takes longer.  There's some give and take between the two, but there is some speed benefits to having more drawings with less on them - checking and modification is faster, avoiding bottlenecks and allowing more people to be thrown at the work.  Its a matter of finding the optimum point between each.

We have some clients which prefer system style isometric and regardless of what program is used generating those isometrics are a PITA.  And I've also worked on projects with bypasses that are separate line numbers, which are also difficult.  So you're not alone.  🙂

Just looking for more options. I say more options the better. Having multiple line numbers on one iso not only can reduce sheets, but also can result in better flow of the drawings. Example of have a simple by pass being on the same page and note flipping through drawings looking for it.

[PeterQuinn]

I have an oddball idea. If you're looking to reduce the number of sheets, could you strip off the titleblock and put multiple pipeline graphics on one sheet using paperspace?

[ralnursyah]

Is there any solution for this question, because i needed to get an overview with multiple line number in one iso

[jabowabo]

There has been no change in the program regarding this issue. Production isos will only include a single line group on an iso. This is very unlikely to change due to the way sheet attributes are populated.
