problem with referencing to a feature in a different body

[Cekuhnen]

I try to make a sketch reference in thee Base body in the sketch for the handle to the sketch for the container in the glass body
I can establish the link to the glass body but then nothing further is found

if i understand it right freecad does not allow this

and the only way is to use the spreadsheet to share a dimension or shape builder/sketch clone??

Are you implying that you want to reference the Glass object from the Base object?

If so, then yes you'd need to use a spreadsheet, dynamic data, or other technique.

[Syres]

Or give @Realthunder's LinkDaily a try, it would appear the user can do all sorts in the Expressions on that build.

[papyblaise]

you can perfectly use external references, but not in PartDesign,
use sketcher and you can select Glass's sketch as a reference, then either open a new body and put the new sketch in it,
or you design the cup holder with Part and you reintroduce it as a basefeature in a new body if you think it is necessary

Good evening to the Community!
I don't know if that's what you're trying to do

[TheMarkster]

I'm not sure exactly what you're trying to do. You want to set a constraint to reference a property of Revolution001? For example, set an angle in the sketch to match the angle used in the revolution you could just do:

<<Revolution001>>.Angle

or if it's a named constraint in the Container sketch:

<<Container>>.Constraints.NameOfConstraint

The Body does not have a local scope for the names of the features. You can see this here where the Revolution in Glass was named Revolution001 since there was already a Revolution in Base.

i am so sorry for the confusion


in body "Base"
i would like to set a height of the handle

equal to the height dimension

in body "Glass"
sketch container

so I know in spreadsheet i can write down a value but i would rather like to reference between different bodies and sample from sketches and features values needed

i hope this is more clear now

...... Have you seen my previous intervention?
Does it seem to me that you explain that or not?

[Cekuhnen]

ah interesting with <<>> you can jump right to a container

this worked
or if it's a named constraint in the Container sketch:

<<Container>>.Constraints.NameOfConstraint
