Continuing routing a pipeline along direction of existing piping component does not work on Plant3d 2023?

[Robert.Soldynski]

Hello,

When continuing routing a pipeline after a rotated component using '+', the pipe does not continue at the same angle (as the flange at 4 deg) in Plant3d 2023. However it does continue in Plant3d 2021. I tried to show all the settings used (snap, compass, cutback elbows) in the recording. Cutback elbow is introduced in v2023 somehow, even though the cutback elbow option is not on.

Plant3d 2023

Plant3d 2021

In the attached video I show the same actions in Plant3d 2021 and then in version 2023.

Same project and dwg file was used.

Checked on our specifications and on a build-in cs150 spec.

Best regards,

There must be a different setting. I am able to route at a horizontal or vertical angle and the CutBackEblow setting is respected.

Hi,

I investigated a little bit more and...

It works in Plant2023 when the angle between the pipe and the world UCS plane is 0 or above ~6 degrees.

In Plant2021 it always works as intended.

Take a look at my wideo below - Plant2023 is on the left, 2021 on the right.

I also notices that the temporary UCS when pressing the '+' sign is different between plant versions. That could be the real problem here.

Can you confirm the problem exists for small angles? (1-5 deg)

Best regards,

Nice find, testing in 2024 also has the issue of angles less than 5 degrees not working properly. Using the Compass settings didn't seem to solve the issue either.

There is a separate cutback angle tolerance setting. It is set in the DefaultConnectorsConfig.xml of your project. And there is a system variable you need to set to enable or disable it.

When you attempt a small angle deviation with a cutback elbow it will ignore the angled placement or implement it based on your settings there. I believe it was introduced after version 2021

Edit: after rereading your issue I think changing the regular slope tolerance will also do the trick for you, don't forget that you need to set this per joint type seperately:

I forgot that slope tolerance was not available through the project setup and just because of your post realized (remembered) it was only available through XML editing. I've made the below idea to add it to the project setup UI so it will be easier for users to identify where tolerances are governed.

Thanks @Michiel.Valcke, setting the Buttweld joint's SlopeTolerance to 0 and turning Cutback Elbows on, allowed the smaller angles to be lengthened by using the plus grip.

@matt.worland  you're welcome 😄 thanks for the likes.

Hello again,

The above solution works as a workaround (slopeTolerance=0) - thank!

However there is still cutback elbow showing up where its toggle is off.

(also in Plant2021)

and:

1. We still need the slopeTolerance to be = 3 for some situations in the project.

2. It works fine with slopeTolerance = 3 in Plant3d 2021! (I mean routing at an angle)

3. Look below at what happens with sT=0 in Plant2023 with compass at 5 deg:

(without compass, it continues at 5) - screenshots below.

(You can only continue at 0 and 10 deg, not at 5 🙂 ; rest of angles works fine)

4. Look at the UCS cube - when pressing '+' it switches to different temporary ucs in 2021 and 2023!

It's the same file with world ucs selected!
