The ARCADY data is updated automatically while the link is active. If for any reason the link is interrupted, a symbol is displayed that indicates that the ARCADY data is out of date. In fact, you will often see this symbol flash up in normal use as you adjust the geometry. While the symbol is displayed, you should regard the ARCADY values with suspicion.
If there is an error in the ARCADY run, the results in the HUD’s will show as ‘ERROR!’. If this happens, you should switch to ARCADY and check the task list to find the cause.
Autodesk Civil 3D 2019 allows you to enter values that exceed the standard subject to a suitable justification. However, ARCADY caps these values before performing any calculations and sends a warning to Autodesk Civil 3D 2019 which is displayed close to the affected arm.
