I have been playing around with DCs a little. The concept is pretty cool, but the implementation less so…
Or maybe my understanding is to blame?
I do understand that a parametric concept has its limitations, but this is not the issue here.
XXX_A.skp (15.8 KB) XXX_B.skp (20.5 KB)
Consider these two very simple attached DCs: XXX_A and XXX_B. They are identical except for one small thing: the formula inside the “Dim” field.
XXX_A is well-behaving in the sense that when you drag it in from the Component tray, a new instance is created (as it should).
XXX_B is not so, when you drag it in from the Component tray a new component definition is created (which we would rather not have).
In XXX_A the field “Dim” carries no formula content, while is XXX_B the field carries the formula
=CONCATENATE(“A” , " x ", “B”)
It appears that it is the text function CONCATENATE() that causes the latter component to misbehave in the described sense. (I made the simplest use of CONCATENATE() that I could think of.)
Surely the CONCATENATE() function is meant to be used in the context of a DC, why would it otherwise be present in the function list??
Anyone to enlighten me? Anyone from Trimble here???
For the record, I am using DC version
the latest I know of.
