How to set conveyor width using code?

I would like to read conveyor configuration from a global table and set it in a script. I used

setnodenum(node(">variables/localType/width", theConv), convWidth);

That command sets the value in the tree, but the visual does not change. I believe there is something I missed to refresh or update(?)

Software Version:

FlexSim 16.2.0

The conveyor's mesh (how it's drawn) only updates when it's told to. You can tell it to update by calling this function:

function_s(theConv, "makeMeshDirty");

Hi, @Matthew Gillespie,

Much thanks for the answer!!. I attached the code you suggested immediately after my code, but not works for me... Still the node values are updated, but visual appearance not... any further suggestion?

Just FYI, I use 2016 update 2..

Oh, I assumed since you were changing the width of the local type that your conveyor is a custom type. If it's not a custom type, you either need to change it to be a custom type, or you need to change the width on the global conveyor type that you're applying to that conveyor. If you do the second option you'd be changing the width of every conveyor of that type in your model and would need to call the makeMeshDirty function on each one to see them update.

I'm also using 16.2 and it's working fine for me. Take a look at this model. Execute the code in the script window by clicking the green play button to see the width of the conveyor change.

Ah ha!!

Yes, you are right. After I changed the conveyor type to Custom, it works!!! Thanks!!

Follow-up question, though.. can you teach me the command to change the conveyor type in code? I don't think just setnodestr()... Very much appreciate if you help me to change the type using a code also.

Thanks!

In this answer I explain how to change the type of a photo eye through code, it's basically the same for any conveyor object.

Hi, Matthew,

Yes, your model works on my machine too. When I do it in the new fresh model, the code works. I guess the previous model I tested seems to have corrupted or something.

THANKS MUCH!! again for your all help!!
