Hope this helps others in navigating the video!

@@AussieBIMGuru Yea thank you so much for breaking it down.

[@morozcot]

I would like to thank you Aussie BIM Guru for your Tutorials very helpful, I appreciate that, indeed, you are really a Guru

[@AussieBIMGuru]

Thanks Maurice! We're all gurus in one way or another 😉

[@archgyanrevit]

Hi mate! loved the video & now I feel I understand lists better. But only practice can make perfect. Could you also share a timeline of the lists you mentioned in the video so that I can jump straight to that list in case I want to check how it works? I'm sure i'll be coming to this video a lot more times. For example: 20:24 Filtering Out Walls based on a Threshold

[@AussieBIMGuru]

Done!

How do you stay so calm when Epic Battle is happening off camera?

[@AussieBIMGuru]

Haha I get used to my cats having a bit too much fun during recordings - they're spotlight hogs sometimes :P

[@ahg3395]

Cheers Gavin, now I hopefully understand Lists at Levels! ;-)

[@AussieBIMGuru]

Excellent! :)

[@shanD7]

Thank you so much for the lessons.....

[@AussieBIMGuru]

Glad you like them!

[@white_shadoww]

I hope you settle things down. Its been so long since you posted anything. Are you still making videos...!

[@AussieBIMGuru]

@white_shadoww probably make next March if all things go to plan. Will be covering a new topic, C# and revit addin development!

[@white_shadoww]

@@AussieBIMGuru thank you for the response. Will be waiting for that... ☺️

[@Akira-xr2zb]

Thank you very much Gavin! Appreciate it! Just a suggestion: it would be easier to understand the functions of List by demonstrating them using Excel sheet together.

[@AussieBIMGuru]

Yes I believe I jump into Excel in the next lesson or thereabouts.

Hi Gavin, I just started to learn dynamo through your videos and they are so good :) My question is that around 2:25 there are three nodes (you called them lists which are area, wall, and length) in the videos. I could not find them. Can you explain to me how to create, please?

[@AussieBIMGuru]

That would be a renamed set of Watch nodes.

[@ketankhorasia]

Hi, i tried to connect the area list to the list.minimumitem and I get this error message 'object must be of string type' also ' remap range shows error. Please guide.

[@AussieBIMGuru]

Make sure your data types are numbers - typically this is necessary for minimum item detection. You can inspect this using the Object.Type node. This may be leading to errors further on in other nodes like the RemapRange.

[@paulacardoso1329]

How do you add color and notes on the background to keep your file organized?

[@AussieBIMGuru]

I use the grouping feature to achieve this. Select a set of nodes, right click and you should find the grouping option there. You can then right click the group to change its colour, and double click the header to change its title.

[@paulacardoso1329]

[@tabio8554]

Hi Aussie BIM Guru, thanks for your amazing work. I've got a question, what is the package for SortListByAnotherList, please?

[@AussieBIMGuru]

I believe this is from Clockwork.

[@shirishdandearts]

Hi Gavin, How to merge items of sublists and match them with the other list's string items? I have been trying to do this but couldn't.

[@AussieBIMGuru]

The list join and list combine node can be used together to join sublists across one another. Beyond that for more specific joining exercises Python may be worth looking into.

[@parimalvala8742]

Hello Gavin, Thankyou for this nice listmanagement lesson. I would like to ask you about "List.SortListOfLists" a node from clockwork package. Could you please explain me that I am trying to understand that node?

[@AussieBIMGuru]

As far as I can recall, this node enables you to sort one list based on the order a list of the same size/shape would be sorted (numerically/aphabetically). Usually, a better node to use is List.SortByKey, where a numerical or alpha list can be used as a sorting guide for a list of the same shape.

[@parimalvala8742]

@@AussieBIMGuru Thank you for your prompt response.

[@dmhb17]

Amazing work! Thanks so much! i just cant find the Node List.CountOccurences...

[@AussieBIMGuru]

I believe this one is in Clockwork package.

[@dmhb17]

@@AussieBIMGuru In deed! somehow it were wrong downloaded ;)

[@Juliet84HMW]

The node "List.chop" is not working for me , could you able to help?

[@Juliet84HMW]

It is still the same list amount

[@AussieBIMGuru]

Strange, make sure the list is flat (one level only) and that the chop amount does not exceed the list length.

[@rocketman1058]

that'd be nice if you put the list of all packages you've used during the video. thanks

[@AussieBIMGuru]

I eventually do this in future videos. I believe i only used clockwork in this one.
