Additional information here: https://developers.maxon.net/forum/topic/12295/bug-with-getlink-setlink-hyperfile/3 Thank you @m_magalhaes & @r_gigante!

My apologies: I didn't understand how BaseLink worked and this clarified things. Thank you!

i forgot to mention: For your next threads, please help us keeping things organised and clean. I know it's not your priority but it really simplify our work here. Q&A New Functionality. How to Post Questions especially the tagging part. I've added the tags and marked this thread as a question so when you considered it as solved, please change the state Cheers, Manuel

Amazing! Thank you Manuel! It works with multiple objects, Cloners etc. Without your help I would not make it

Hi @C4DS , maybe I wasn't enough clear. you end up with a single merged object, which has 2 selection tags, and both still have the specific name ... but none have the added unique ID. Surely you start to think something is really wrong. Actually you end up in a new mesh with new selection tags which beside having the data copied from the two source selection tags, they are NEW and hence the UniqueID is not supposed to be kept. The names are kept for convenience but I don't see any reason to have also the UniqueID being kept considering that - in the end - they are indeed new instances and have nothing to do with the source selection tags. Cheers, R

Hi @C4DS, thanks for following up. One note that it's worthy to share: the outcomes of this thread are valid as long as you need to stick to Classic API. In Maxon API (R20 and higher) you can make very good use of the CustomDataTag (see also GitHub example) whose data merging is managed directly by the modeling kernel. Last but not least, as usual, if the discussion has come to an end, please don't forget to mark the question as SOLVED. Cheers, R

hi, thanks a lot for sharing your code Don't forget to change the state of this thread to solved. (if it is) cheers, Manuel

@C4DS Although a solution has not been given (as I wish to do), explanations have been provided. I have therefore considered it resolved. For IRL reasons, I could not do so. I will be able to get back to it, and if I find THE solution, I will post it

@m_adam Terrific work, Maxime! This is very helpful to me and I'm sure the many others who want to learn about dragging in Cinema 4D's UI. Excellent job!

hi, no trouble at all, you are here to ask questions, we are here to answer. Cheers, Manuel.

Thank you! That does it exactly!

@m_adam You are a genius! Thank you, Maxime

Hi Kantronin, thanks for reaching out us and welcome to PluginCafé. To make Cinema 4D programatically executing modeling commands, you can make use of SendModelingCommand which properly satisfy your scope. Aside from the example shown in the documentation you can also have a look at this post from @maxime and this other post about Optimize command. Last but not least be aware that the modeling command settings are specified in the BaseContainer passed to the SendModelingCommand and whose parameters can be found in the MCOMMAND page. Finally please remind to use Tags and Ask as a question for any future support entries

@C4DS That was the most normal happy smiling glad you solved your issue emoji I could find. Any of the others could definitely have been interpreted in many ways. Hope that one came across alright

@m_magalhaes Thanks for reminding me of the GeDialog::CoreMessage. I totally overlooked that.

Great example, thank you. -Pim

Hi @pyr, I've just reached the development team about it. So for them, this is not a bug since FieldList store only baseLink. In Python, we don't have BaseLink, but if you are not aware of what it is, please read BaseLink Manual. But since there is no BaseLink in Python, if a link points to a destructed object (like in your case, Python simply returns None) So I guess your workaround is ok. Cheers, Maxime

@C4DS Thank you for your help! It works！ Cheers~

Yes, that solved it. Thanks.
