Hi there
Here code is same in both image but it works in image 1 where as in image 2 it shows error. Can anyone suggest any solution to this, that why this happened ?
Below image 1
Below image 2
Below image 2
Could you explain what you are trying to do? is it the same graph in image 1 and 2?
please upload the dyn
retipe the code block:
a=Point.ByCoordinates(0,0,h);
Plane.ByOriginNormal(a.Vector.ZAxis());
something strange is going on in your second graph there is a input called point and plane
it’s not working.
again error Warning: Internal error, please report: Dereferencing a non-pointer.
ok. I got it now. You must have copied the nodes into a new graph.
try:
a=Autodesk.Point.ByCoordinates(0,0,h);
Autodesk.Plane.ByOriginNormal(a.Vector.ZAxis());
try restart computer
a=Autodesk.Point.ByCoordinates(0,0,h);
Autodesk.Plane.ByOriginNormal(a,Autodesk.Vector.ZAxis());

yes, It’s Working. 
I’m not sure what node the script in the code block is calling
look here:
Try installing the Dynamo Text package
Install the package I mentioned above and then write in the code block
DynamoText.Text.FromStringOriginAndScale(txt<1>,pt<1><2>,1000);
I got the Text in code block.
You forgot something. Look above
i tried, but it’s shown something error. so it’s not useful for me.
Thanks mate
