Test error check

Hello! I’m trying to create a line in revit through Rhinoceros (I´m using Rhino WIP and Rhino.Inside):

The problem is that, everytime a make a line, point or so in the Rhino Window and try to “Set One Curve” in the Grasshopper window, I get this message:

And the results are that my Revit reminds empty:

I will appreciate your help!!

Thank you in advance.


To disable this dialog Copy the following line into clipboard and Paste it into the Rhino console.

_-TestErrorCheck _E _O _Enter

It worked!!! Thank you!

Hi Kike,

I have another question about this.

Every time I begin Rhino and try to make a command, I see that error and I have to paste _-TestErrorCheck _E _O _Enter all the time.

Is there a solution to get rid of that window once and for all?

Thank you in advance,


It’s strange. Do you have Rhino SDK installed?

Anyway, you can add this command here to run it every time Rhino starts.


What is Rhino SDK? Grasshopper?

I did what you sujected and the error is still showing.

Thank you in advance.


Have you restarted Rhino.Inside Revit?
I didn’t mention it before, but you need to restar it in order this command runs at least once on the next start.

Rhino SDK is the Software Development Kit.
You can check if it is installed going to Windows Settings>Apps & Features and filter by “SDK”.
If Rhino SDK is installed it will be listed there like this.


At last I decided to go back to Rhino 6 because I was getting to much trouble with the Rhino WIP and Rhino.Inside. So the last issue I sent you (The one with the command _-TestErrorCheck _E _O _Enter) is happening to me in the Rhino 6 version.

On the other hand, I don’t have Rhino SDK installed. Should I install it?

Thank you in advance

No, you don’t need it.
The Rhino SDK is the Rhino software development kit, is only needed in case you want to develop a C++ plugin for Rhino.
I asked because when this kit is installed Rhino becomes more verbose showing errors even if those errors are not relevant for the final user.

I’m confused now, is this error showing in Rhino 6 or in Rhino WIP inside Revit?
