filter function confused

[hx]

About the filter function.
I use the filter function to get toolpaths which is set rest.active.

ENTITY LIST EntityToolpaths = filter(folder('Toolpath'), 'AreaClearance.Rest.Active==1')

But when I use filter to the toolpath which where use specify tool, it raise error infor.
Can somebody tell me why.

ENTITY LIST UseToolToolpaths = filter(folder('Toolpath'), "Tool.Name=='1'")

How can I to get the toolpath list which was use the tool 1.

ENTITY LIST UseToolToolpaths = filter(folder('Toolpath'), "Tool.Identifier=='1'")

Problem: The Tool.Identifier  not necessarily unique...

The problem that you'll have is if one of the toolapths' doesn't have a tool. In such cases '"Tool.Name' will raise an error.

Try something like:

ENTITY LIST UseToolToolpaths = filter(filter(folder('Toolpath'), 'entity_exists(Tool)'),"Tool.Name=='1'")

the inner filter will return a list of toolapths that have a tool to the outer filter which then returns just the toolpaths that use the Tool named '1'.
