FamilyInstance.ByHostAndPoint / Reset Default Instance Elevation

[da5id]

@Dimitar_Venkov

Respect for creating Spring Nodes.

Noob. Using FamilyInstance.ByHostAndPoint to insert wall based families. If any other instances are inserted manually with altered properties, the default elevation parameter is set to zero and any future instances inserted by the command are inserted at elevation zero.

There is a workaround to escape out of “Create Similar” option for any instance without inserting geometry to reset parameters to null. ( https://bimchapters.blogspot.com/2018/12/resetting-default-instance-parameter-in.html )

Is there a code block or Dynamo command i am missing to effect this reset prior to creating instances?

Thanks.

If I understood the linked article correctly, all you have to do is run the “CreateSimilar” command to restore the correct defaults. If you want to do that automatically at the end of the script, you could try using a PostableCommand:

Rhythm: PostableCommand.CloseHiddenWindows gone?

You can download the old package and extract the Python script. Although, I would advise being on the latest version of Rhythm if possible. I dropped that node for a few reasons, It’s a .DYF custom node. I am working on removing these from the package completely and being 100% ZeroTouch C# nodes. The method changed in the Revit 2019 API from PostableCommand.CloseHiddenWindows to PostableCommand.CloseInactiveViews. So rather than rebuild the logic, I dropped it. That being …

Thanks for getting back. ‘Create Similar’ methodology does work well. Hoping to create something a little more refined and user friendly. ( be nice if autodesk did the same…)
