You need to find that object in your model and check its settings.
You probably have a zero or negative length in a parameter that the object does not like or possibly other settings are causing this error.
Experiment with the settings or start with a new object and make sure you have the 3D preview active as you set it up again.
Then you will see the message appear when you make the setting that causes the problem.
If you can't find this object (or maybe you didn't place it but it is being called by another door? object) then use a marquee to isolate portions of your model to view in 3D to see if the error is there.
If not maquee another area and if it is then marquee a smaller portion of the problem area until you can determine the object causing the error.
