Here is a formula for a Datum Surface:

CompleteSurfaceDatum = assemble(RESULTS_BODY ->Query("GSMSweepUnspec","x.Name==\"Seal Groove Remove Tool\"" ) )

I get an error claiming I am trying to valuate a Surface with a function returning a Curve. This seems to be because  there is assemble() for curves and assemble() for surfaces. And only assemble() for curves seems to work with a list..

If I make a List feature and try to use that it is no better.

Does anyone know a way to work around this?

 

 

 

Hello,

I don't think there is one...

This is a limitation with list management for functions that have variable arguments number : the function to use is chosen when parsing the expression, not when executing it. We can not know what will be the content of the list at that time.

Hi Cliff,

You can use brute force method to join them one by one. I did this in an Action feature below (so it is easily reusable in other projects too).

---------------------------------------------------------------------------

First create the action...

The arguments will be an input list and an output surface,

iList : List,oSurface : Surface

The action body will be,

Let S(Surface)
Let S2(Surface)
Let i(Integer)

/* Join first 2 surfaces */
S = iList->GetItem(1)
S2 = iList->GetItem(2)
S = assemble(S, S2)

/* If the list has > 3 surfaces then join them as well */
if iList->Size() > 2
{ i = 3
for i while i <= iList->Size()
{ S2 = iList ->GetItem(i)
S = assemble(S, S2)
i = i + 1
}
}
/* Return the joined surface */
oSurface = S


Then, you can call the action from a rule or other relation....a quick example,

Let S (Surface)
Let L(List)

L = `Geometrical Set.1`->Query("Surface","")
Relations\Action.1->Run(L, S)
`Geometrical Set.2\Surface.1` = S
