|Summary||0004781: Issue with Linear Pattern in the Part Design workbench when replicating an Additive Pipe based on an elliptical path.|
|Description||I am trying to use Linear Pattern to duplicate a flange on a pin. The flange is created using an additive pipe which uses a path sketch involving an ellipse.|
This doesn't work.
I have queried in the forum to see if this was:
- a known bug (doesn't seem to be)
- more experienced users can get it to work (they can't)
- more experienced users thought it might be a bug (they do)
Forum link: https://forum.freecadweb.org/viewtopic.php?f=3&t=63409
I have taken my sample from the forum, improved it based on their feedback and simplified it a lot more. I have also included a comparison of using a circle (instead of an ellipse) for the additive pipe path and this seems to work fine with the linear pattern feature.
In the linear-pattern-attempt-1.FCStd you will see:
In the linear-pattern-attempt-2.FCStd you will see:
|Steps To Reproduce||Open the linear-pattern-attempt-1.FCStd file and observe that:|
- the linear pattern using the feature of an additive pipe based on a circle path sketch IS rendered.
- the linear pattern using the feature of an additive pipe based on an ellipse path sketch IS NOT rendered.
Open the linear-pattern-attempt-2.FCStd file and observe that the linear pattern including both additive pipes is rendered incorrectly.sketch is not rendered.
