Olet and Isometric drawings

[JohnHolder]

Well I finally have my flush bushings working.  Now the issue is with my Olets.

Olets break the ISO

In the Spec editor for my olet, I originally had the connection as TAP / PSW - tap going into the larger pipe.  With this, ISO's worked, but there was no connection between the olet and the larger pipe - the center red line was not connecting the pipe lengths to the olet.

I changed the connection from TAP to Universal_ET and now the center red line connects the pipe - including the olet, but it errors out the ISO and they do not generate.

Then I tried Undefined_ET and it does not connect, similar to TAP, and it errors out the ISO as well.

*edit* also BV - which connects but errors out ISO.

Sooo any ideas on how to set up an olet so that it works with ISOs?

I am using an olet as a pipe saddle ( PVC Sch 40 ) bolted or glued and strapped on, so it functions like a reduction tee.

[JohnHolder]

Using BV and PSW work, they connect the OLET properly, in the drawing even though BV is not the correct connection type.

Iso Symbol Type: OLET1 ( changed from OLET, which breaks the iso )

Iso Symbol SKEY: SKSW ( also tried different letter codes from demystifying isometrics )

Now when I create an ISO, the OLET symbol is not shown, and the reduced pipe is put on to a seperate page

6" pipe both ends shown open end. overall length shown.  the lengths on both sides where the olet connection should be are shown.

4" reduced pipe is shown on a seperate page.  Where the OLET connection is it is blank, the open end is tagged correctly.

I would add the DWGs but when I browse, then <add attachement> it scrolls to the top of the page and does nothing.

so I cannot attach.

Create production Iso <advanced>

override iso splitting - force iso onto one sheet checked

I cannot upload files, so I made a quick video showing the process and what the iso's look like.

[ybogdanov]

You have ISO Type: OLET1
And this value will be OLET (without "1")

[JohnHolder]

Changing it back to OLET and the ISO errors out and does not generate at all.

The ISO is saying there is a disconnect, but there is no disconnect in the drawing.

Have you tried to add the attachments again here lately? I am curious is this is a problem in the forums and if this needs to be addressed.

[JohnHolder]

It is a forum issue.  it ONLY supports internet explorer..

Even when using internet explorer, reciently I am having issues with attachments.

I <Browse> find the file I want to upload.

usually I am scrolled partially down the page

I hit <Add Attachment> and it jumps to the top of the page and nothing happens. ( file is not attached )

( I only use chrome, and the all of the forum options do not work - same issue with jumping to the top of the page.

I have to remember to use internet explorer which is slightly annoying )

For our OLETS the connections are set as follows Port 1 (S1)=BV, Port 2 (S2)=SW. (not PSW)

[JohnHolder]

SW seems to not play nice with PPL Are you using PVC?

[twodogs_2012]

John, we use mostly PL for the ends on the pipe, even SS and CS (instead of BV). Not tried the PPL. We do know that certain end connections, even though more proper, do not iso well so sometimes we have chosen to use more simple end connections. I think, although going on faulty memory here, the THDM instead of PL can cause issues and PL works on thread-o-lets. I believe we're talking sock-o-lets here. Thanks.

[JohnHolder]

Unfortunatly my background is not in piping - I have had to learn everything on my own. ( most likely use the wrong terms )
I design land based recirculating aquaculture systems and do all the CAD work to build them.  luckly for me, the piping involved is quite basic and only deals with Sch 40 PVC / HDPE and PVCu and Metric HDPE.  the vast majority being Sch 40 PVC.

Basically I am trying to recreate a pipe saddle which P3D is an Olet. - the sock-o-let.

What seems to be happening, there is a pipe disconnect in the ISO, but no disconnect in the drawing.

Which has been recreated.  I seem to get all the errors that nobody has seen since I don't fit any moulds in the industry.

Everything I do up ( exception to HDPE ) is PSW / PPL glued fittings which makes it quite simple.  But any insight on how to handle things

in a different easier way is welcome.

On the attachment comments, other users have not been able to post attachments due to a 3rd party tool called AddThis that Autodesk uses.  IT may have to allow AddThis in order for attachments to work. I believe Autodesk is checking into the issue.

I think we've gotten beyond where I will be of any help. A silly question, do you have the "Disconnect Markers" turned on (found in the "Visibility" part of the "Home" ribbon)? That would show whether the piping is actually connected. I copied a sockolet in the spec editor and called it a PVC Saddle set Port 1 to PPL and Port 2 to PSW added it to the PVC spec and it connected and the iso ran as one piece with a branch. Also assuming you're using the PVC pipe and fittings in Plant 3D which is set to end connecitons of PPL, PSW, etc. If that process is not working then there must be something else that is not obvious.

[JohnHolder]

not a silly question,  Yes tried it.  The wierd thing is that it is connected in the drawing, disconnected in the ISO, and it has been reproduced by another person.  It has been elevated now and a Specialist is also working on it.  I am using some of the fittings, since sch 40 pvc that ships with P3D as well as the Spears pipe pack are missing way to many components.. a good chunk of the piping I use is custom.  All set for PPL and PSW - all which work in ISO drawings except for this.

The wierd thing now, I just found another instance where it is happening to a 90 Ell.  Connected in the drawing, disconnected in the ISO but 90 Ells work fine in other places.

It would really be nice to get to the bottom of this issue.  I normally do not use ISO's but it would be nice to have the option.

John,

For Pipe Saddles (PE or PVC), I've created a 3D block and added 2 ports:

The connectionport 1 (in the centre of the pipe) must be perpendicular to the centre line of the pipe and not in the same direction.

This direction needs to be in the opposite direction of the thread connection.

See attached picture.

As Type I used OLET and the SKEY is HCSC

It works fine without disconnected pipes.

Hope it helps,

Marc

You may also want to check the isoconfig.xml Split points.

First, save a backup copy of your xml.

Open isoconfig.xml in a text editor, foxe is helpful for the tree menu, but you can use notepad as well.

Search for "SplitPoints".  Check to see if there is anything in the split points that would be splitting the iso generation at an olet.

I was once stuck on a split at on olet.  It turned out that there is a setting for spool drawings that is call MaxDirectionChanges.

It could be something in the split code of the xml

I had the same issue right now, the o let would generate in another drawing. Thanks a lot this helped me out.
