I am getting this problem as well....I have even opened a standard part and copied and pasted the correct equation from there to my new part....and it still doesn't work. Anyone have a solution?
This issue has been reported to Autodesk for C3D 2013. I had the same problem when I was trying to change my wall thickness I go the same error. So since I could only set one constant wall thickness, I just add the difference to my structure inner width and length (SIL/SIW). For example. Most of my structures walls are 6 inches but I have a 7' junction box with 8 inch walls. To fix this issue, besides using 84" for the inner dimension (SIW/SIL) for my box, I used 84.34 inches. Now my outer structure limits are correct. Maybe you can try this method.
Has anyone seen a fix to this issue?
I am experiencing a similar issues with Civil 3D 2014 where the part I created will not have a proper height based on the equations I assigned. The .xml file does show the correct equations, but the structure height doesn't seem to obey the equations. All other parameters seem to be correct when I insert the part, just the structure height keeps being shown as 0.
Attached are the equations I have used.
Partbuilder is very touchy. Please check the generated XML file and validation files for errors.
Depending on what you add context wise to the model and configure duplicate references can be introduced into the Xml file - See Below.
<ColumnConstList desc="Suds Height" dataType="float" unit="mm" name="SudsH" id="CCL1" visible="1" context="Geometry_Distance2D" index="1">
<ColumnConst desc="MainBoxWidth" dataType="float" unit="mm" name="SudsH" id="CCA1" visible="1" context="Geometry_Distance2D" index="1">$0.000</ColumnCalc>
So the above two lines from the xml should explain what I mean. You should only have one instance of each context listed otherwise the part will only use the second one listed (due to the index).
To fix Delete the second entry with the constant 0.00 value and index greater than 0. Next change the very first instance found (ColumnConstList) to as below.
<ColumnConstList desc="Suds Height" dataType="float" unit="mm" name="SudsH" id="CCL1" visible="1" context="SudsHt" index="0">
The context (SudsHt) should be as correctly listed in the AeccSharedParams file and must have an index of 0. Be aware if you open the part in part builder again you will need to repeat this process. To add additional sizes I recommend adding through notepad or an xml editor adding "<Item id="i#">000.0000</Item> or Irow etc.
The above is mainly true for custom added contexts however still applies if you have added existing ones which were not originally defined in the part.
I'd be happy to look into any problems if you supply the part data files (dwg & xml).
