Previously placed elements get overwritten when I try to place new elements

[Bim]

Hello everyone,

I’m new to Dynamo. I have a very serious problem. Can I run a node more than once without me erase what I did initially? For example, I run a node that make me levels (elevation and name) but then I would like to add new levels. once again run for the second time, running for the first time are eliminated.

that is just the way Dynamo works

Perhaps in the future there could be a ‘commit model updates’ but for now, the only option is to close the dyn and reopen it

I’m not sure if it works with levels but it worked for me when I was trying to place beams. Try to save the dyn file after creating the new levels.

Refer to the below discussion:

Beams at Adaptive component location(Mass Family) with Dynamo

Try saving your definition after placing the beams. That should store the beam guids inside the *.dyn file and update the already placed beams the next time around. You’ll know it has worked when your *.dyn file increases in size significantly. Here’s one possible alternative, similar to what Konrad suggested:
