# Troubleshooting

## Current Limitations of CSiAPIv1

Some current limitations of the CSi API are listed here:

* Cannot add custom grids except via database method (implemented w/ Kudu);
* Add/edit stories method fails to complete if objects exist or have existed in the model; user must manually edit stories or start new model from existing file;
* Delete method is very slow if ItemType=Object is used;
* Cannot draw design strip objects except via database method;
* Cannot draw tendon objects in ETABS, SAFE except via database method;
* Cannot assign automesh option to objects in ETABS, SAFE except via database method (implemented w/ Kudu);
* Shell uniform load sets cannot be defined or assigned except via database method;
* Certain assignments cannot be made with the Group or SelectedObjects ItemType;

## Common Messages

{% hint style="warning" %}
No running instance of the program found or failed to attach.
{% endhint %}

This message occurs if no running instance of the SAP2000, ETABS, or SAFE can be found. The user must open an instance of the program and open or create a new model and attach to it with the Attach component found in the Kudu>File tab.

{% hint style="warning" %}
API script failed to complete.
{% endhint %}

This message occurs if the API script fails. This can be for any number of reasons, including but not limited to the following:

* The model is locked (Edit, Define, Draw, Assign components);
* The object being drawn already exists in the model  (Draw components);
* The unique name for the object being drawn already exists in the model (Draw components);
* The property name for the object being drawn does not exist in the model (Draw components);
* The object being drawn does not exist at the Datum defined in SAFE (SAFE only);
* Both ends of a frame element are released in axial, shear, and/or torsion (Assign Frame>End Releases)

{% hint style="success" %}
API script completed successfully.
{% endhint %}

This message occurs when the API script completes successfully.
