The error is cause by dependency loop, as shown in the error message. The loop is formed by three object,

Sketch, Spreadsheet, Sketch005

Sketch reference Spreadsheet in its constraint
Spreadsheet reference Sketch005.Shape.Edge2.Length in B17
Sketch005 reference Sketch in its external (i.e. imported) geometry.

There is a way to work around the cyclic dependency reference. Use the href() function, href stands for hidden reference. Be warned though, this is an advanced feature. The dependency loop will cause unexpected recomputation problems, because of unstable recomputation order.

href(Sketch.Shape.Edge2.Length)

Also beware that direct referencing to Sub-element of a Shape will get you in trouble with topological renaming when the shape is modified. Use the following syntax for more robust referencing,

href(Sketch.<<Edge2>>._shape.Length)

Forgot to mention. The recommended way of solving dependency loop here is to split the Spreadsheet into two if possible.

@realthunder anything left to do here?
