  1. Hi @Nomi - The reason this is not working in your node is because vs.SetStoryElevation() takes mm as the input. You need to convert your document units to mm and then use that value as your elevation. I recently posted a network that creates a series of stories based on an overall building height. There is a Set Story Elevation node in that network that shows how to do this.

    Just one situation to report: the precipitation chart doesn't work for my location. I attach the file so you can see if it is something from my location (absense of data?) or


    Yes, unfortunately the precipitation data can be incorrect - these weather stations will often report precipitation as 0 when they should be reporting it as "missing" or "unavailable." It only seems to be true of the precipitation data. I haven't been able to figure out a solution.

    Regarding using a network without making it a menu command... whether it's in the form of a symbol or not, the idea is that you place it into the drawing space of whatever you're wanting to use it to work on, and then delete it from there once it's no longer needed?

    Yes this is correct.

    Once it's in the drawing space, what does and doesn't it act on - does it act on anything in that file, or just on that design layer?

    It depends on the network/wrapper. Whatever the criteria of the network is, that is what it will act on. Most menu commands are created to work on selected objects, which is not possible with regular networks (because the network and the network alone must be selected in order to run),  but if for example your network is set to look for every rectangle and change the attributes of them, it will do that, no matter what layer each rectangle is on. I have attached an example file doing this - each rectangle is on a different layer, and no matter whether the layers are visible or not, modifiable or not, the rectangles are changed by the script. If you want to specify layers or perhaps visibility, you can do that with the criteria node. To test this out, go to the criteria node in this script and add the criteria of visibility.

  4. hello @line-weight - the Marionette menu commands that you create live in a file in your user library.

    You can see in the image that I have a single menu command: Rotate X 90. If I wish to remove that menu command, I can open that file, go to the resource manager and delete that wrapper. If I wish to edit a menu command, its a little trickier. I can open that file, place the wrapper in the drawing space, edit the wrapper then RESAVE it as a menu command. If you give it the same name as the old menu command, the new one will replace the old.


    If you wish to save a network to use in multiple files but NOT turn it into a menu command, you can simply wrap that network and save that wrapper as a symbol. If you have "Convert to Plug-In Object" checked when you convert it into a symbol, it will be a wrapper when you place it in a new drawing. You can transfer it to other files just like you would transfer a symbol. You can also see in the image of my Resource Manager that I have a favorite file called My Custom Nodes. That is where I keep custom Marionette nodes as well as wrappers in the form of networks that I may wish to use in multiple files. It's easy for me to import from that Favorites file into any open file.

    I hope that helps.


  5. Perhaps you could try using the group node to group all of your points before changing their layer? In general however, I would recommend simply running the network with the layer that you want the objects to end up on as the active layer. 


    I also assume that it is the act of setting the layer that eats up the most time and not setting the class. Have you experimented with only changing the class?

  6. Hello All,


    Sorry I was late to respond to this, but there was a bug in the 2019 version of the node and I used a custom version of the Collate node. Besides the output not being lists of lists, the biggest difference between these two versions was that my custom node was looking for the number of items in each list while the default library node is looking for the number of lists. Here is a file with a slightly adjusted network that uses the fixed default Collate node in 2020. I exported it back to 2019 so that you can use this correct node in version 2019.

  7. Yes, @Dishav Vasudev there is now a node in the default library that allows you to do this. Its called the Popup Dialog node and its in the User Interaction folder. the way it works is that it takes a list input generated by the script and when you run the script, a dialog pops up and allows you to choose from a dropdown of that list.

  8. You are on the right track and very close.


    If you want the output value to be a symbol name, it needs to be a string. In order to create a string in your script, you must use quotation marks. Assuming that HR4 is the symbol name, you simply have to put quotation marks around it to make it a string.


       if input == 0:
            self.Params.output.value = 'HR4'
        if input == 1:
            self.Params.output.value = 'HR5'
        if input == 2:
            self.Params.output.value = 'K4'
        if input == 3:
            self.Params.output.value = 'K5'

  9. If your NURBS surfaces always follow the same curvature and change only in the length that they lay on the floor, you can create a bunch of surfaces that are the same size, then use the Extend NURBS node to extend each in a random manner. The Extend NURBS node only takes a single length value as the extension, so inputting a random list of lengths to extend a list of surfaces should work.

  10. Hi @cberg-


    Oh, the Space tool. There is a way to do this but its hidden. The parameters of each finish "key" are there in the space but they don't show up in the dropdown menu of the space's object parameters. I am not sure why this is true. I have built a data tag that is set up like the image you provided. I don't believe there is a separate trim finish in the space, only a base finish, so that parameter isn't included, but all the others are.

    Let me know how this works!

  11. From a scripting standpoint, I think you could easily put these objects in separate classes. Putting them in separate layers can be a little trickier, because the created geometry is always placed in a group and that group will be placed on the active layer, no matter what layer the objects INSIDE the group are on. The way around this would be to place your starting objects on the layers that you want them on, and then run your script with the active layer set to the layer that you want those objects placed on.


    You can do this within the script with classes using the Set Class node from the attributes folder, or with layers using the Set Layer node from the Layers folder.

  12. I noticed that your rectangle nodes are named and when I remove the Int node then those names appear on the outside of the wrapper. To keep this from happening, you can attach a 2D Vector node with the values of 1 for X and 0 for Y to the vRot inputs of the rectangles. Those are the default values for no rotation.

  13. Hi @Palle-

    It looks like you have an integer node attached to the "vRot" input of the rectangle nodes in one of your wrappers. This input requires a vector - that is what the "v" means. It looks like all of the Int nodes you are using have a value of 0 so you are not looking to rotate any of the rectangles. If you simply remove these Int nodes and leave those rectangle inputs open the script will work how you want.

  14. You can think of this node as an alternative to the Bool input node. The output of the Yes No Dialog is labeled "b" meaning it is a boolean or true/false value. Yes would be true and no would be false. You can connect it to any node that has a "b" input and some sort of either/or choice. When you run the network, a yes/no dialog will pop up and you can choose Yes or No.

  15. I wonder if figuring out whether the church is visible would work better if you project from the other direction - from the church. If you have existing buildings and trees in your model, I imagine that you could create a projection from the church to the location of the building - all the building would need to be is a flat surface - and where the projection of the church hits the surface (isn't blocked by other buildings, trees, etc) is where you know that views of the church exist.

  16. I believe it would just be easier to make the multipliers (1,2,3,...) the output of the popup and multiply that output by 12 or whatever variable integer. Again, you can use the Popup node if the multipliers will always be the same, or you can use the Popup Dialog node to have a dialog appear after the script is run. The output of the popups are integers representing the index value of the item chosen from the list. Since your list will basically be 1,2,3 etc you can add one to that integer to get the value you need. I have built some examples for you.
