Parametric family error message

[Anonymous]

Hi,

I am trying to make a parametric slat wall where the width of the slats is the parameter. Getting an error message that I don't know how to decode. Does anyone understand what it means and/or how to fix my drawing? 

I created the reference planes first, then added dims to them. Next I extruded the horizontal pieces and locked those to the planes. Then applied the parameter to the dims. 

See attached image for more info. The error message is:

Error 1

Reference Planes : Reference Plane : Right : id 3541

_ Extrusion : id 5812

_Constraints : Linear Dimension Style : Sligment : id 11282

Error 2

Reference Planes : Reference Plane : Left : id 3623

_ Extrusion : id 11103

_Constraints : Linear Dimension Style : Sligment : id 11305

When I added an additional dim  over top (see second attached image), the error message is

Error 1

Reference Planes : Reference Plane : Right : id 1056721

_ Extrusion : id 1056826

_Constraints : Linear Dimension Style : Sligment : id 1056848

Thanks for the help!

You overconstrained with two strings of dims: 6-11 width and 3-4, 3, 3-4.
Remove the 3-4 dims and lock the 3.

Hi,
thanks. If I understand you correctly, tried this on the version with the 6-11 dim -- only the 6-11 has a parameter, the 3 is locked. Do you mean remove the 3-4 dim altogether?

Model those slats as a separate family with width parameter, load it in, link the parameter, create the array and lock onto the reference plane on 1 side.

FWIW: Seems like a lot of work when this is something that you could do with a Curtain Wall in a matter of minutes. Serious. A fully parametric construct in minutes.

Thanks for the tip. I will have to investigate further.

Thanks. For some reason I couldn't load the separate family, so I did it the long way. The error messages seem to be related to the array (the original one without the slat as a separate family). Instead of the array I copied the geometry multiple times. I had lock every slat to its outer reference plane. That worked. I'm pretty new at this, so will have to investigate more later. Thanks for the input.
