That Vector.X node is the X component of an existing vector input. There’s another similarly named node that will give you a vector of the x axis.

Hello @mmegc,

Drop out the node results and you will see the vector.x node doesnt return a vector. This is because it expects an input vector. As you dont feed anything to the input the node returns a function.

If you just want to get the base x vector, you are using the wrong node. Type “x” in the dynamo dearch bar an you’ll find it.

You’ll have to do some troubleshooting. What is the output from the Dimension node? Do the element Ids exist in your model? Does the view have dimensions turned on?

hi, nick,

dimension is turned on in the view.

in my dimesnion node, there is no out put.

but what do you mean does the element id exist?

sorry, gideon

The node implies that it returns the newly created dimensions. Those would have an element Id that you could check. If there’s no output then something is obviously not working. Can you show us the full graph with all node previews pinned after it’s been “successfully” run?

All Elements of Category isn’t returning any elements. So there’s nothing to dimension.

For wall types, you need to use Element Types and All Elements of Type (or Element Classes and All Elements of Class in the latest version).

It could be that the custom node doesn’t do what you want but you’re also not providing a valid class name. Use the out of the box Element Classes node so you can select the appropriate Wall Types.

“Basic Wall” and “Interior - 41/2” aren’t element classes.

If you use the ‘Element Classes’ node you’ll see all valid element classes in the dropdown.
