That’s not good.
I am guessing you have you tried the following:
- Restart Revit, and therefore Dynamo.
- Use the Open in Manual Mode toggle when opening the file.
- Checked you haven’t saved the 1.3 version graph in 2.0 format by mistake. (open the dyn as a txt file and look at the formatting)
- Check for backups of the graph in the Dynamo folder in your user data.
- Temporarily unloaded the pointcloud before opening Dynamo, just in case some weird binding is going on.
Can you start a new Dynamo graph alright? Is this behaviour specific to the graph you have been preparing, or does it happen for a previously created graph as well? (Backup any other dyn file before testing, in case there is some kind of corruption going on)
I hope some of that helps and you can get it running. I can sympathise as I have lost entire workflows from file corruption (from how our server runs) in the past…
Hi Ewan,
I have re-created it and tried again the double up of your node:
It works on occasion. Most of the time no points are selected as per image. Bloomin’ Dynamo.
The script recreated had been working fine upon a given location of point cloud and now returns nothing. Dynamo is so fickle which renders it unreliable most of the time.
Sadly l shall stop.
One minute it works, next it doesn’t, then if it works if returns a completely incorrect diameter pipe etc. ahhhh
90% of my best stuff starts in this version of ‘Dynamo’

Try running this via Dynamo Player, or closing without saving the graph between runs. It sounds as if you’re up against an element binding issue.

Here is an example workflow for when you have a decent length of pipe scanned.
(I will see if I can find some time this week to test a partially scanned pipe as well)

For incomplete pipe point information (vertical pipes only)…

Hi @dineshsubramani
This node has been updated (issue found previously) and is available for download from my website. Hopefully replacing the dyf in your packages folder solves your issue.
Sastrugi Package - Updated
This update will be included in the v2.0 release. (date pending)

Thanks a Lot @Ewan_Opie
i continued the script and i got another issue the circle is formed in the opposite direction may i know how can i sort it out
Thanks in Advance
Check that the Lacing on the Geometry.ClosestPointTo node is set to CrossProduct, so that all the surfaces and points are considered.

Ewan,
Many thanks for further input.
I shall look at what you have posted.
Did you say that your nodes downloaded a few days ago have been updated?
Ewan,
Hi.
I tried your variation, however, no joy:
I have got it to occasionally work, and you have got it to work, however, it does appear to be hit and miss, mostly miss
Dear Dinesh,
