Thanks, I will copy your explanation into the wiki if you don't mind.

I'm not sure which resoltuion to use for ConvertToPolygon(). http://developer.vectorworks.net/index.php/VS:ConvertToPolygon <50 is obvious to less. 90 and 100 convert a cirlce to 32pt polys and 150 to 64 pt polys. In this case 90 should be enough as even in renderworks my eyes can't spot a difference to the higher resolutions. It would be good to know how the resoltution effects the outcome (why do 90, 100 create the same ) and if there is a maximum value. regards, Patrick

To make sure the center stays at the same location the bounding box must always have the same size. This can be accomplished by palcing an invisible circle into the symbol. ( set fill and penstyle to empty.)

This node gives you the center of the Bounding Box.

I looked it up in the source This list should contain all the real nams. univ_nams.txt

The internal name can differ from the display name. In your case it's Rebuild Curve/Surface regards, Patrick

FPenPatN is the solution. thanks

It might be obvious but I can't find the fucntion that returns the active LineStyle (Attribute Palette). Can someone give me a hint. http://developer.vectorworks.net/index.php/VS:Function_Reference#Document_Attributes Patrick

You can find additional indo and more examples on http://www.vectorlab.info I would recommend you pyodbc (or pypyodbc*) for the sql connection. It is easy to use, more stable and performs better than the vs. functions. * Almost totally same usage as pyodbc ( can be seen as a re-implementation of pyodbc in pure Python )

Hello, I need to call a Pythonscript (200 Lines!) wrappt in a VectorScript. Can you tell me how to get it between the brackets in VS? PythonExecute ( ?Load Pythonscript from external file? )

Function is a great timesaver node. Here is a version with two more optional params. I have to contain myself from using it to extensive because the readability of the code could suffer. It would be great for the future if the function was displayed on the node. function_N.vwx

Couldn't find a description in the online help. How is it done?

thanks Dom, I wonder why the criteria-dialog only calls a string-dlg as there is a more sophisticated dialog available. Here is the alternative version: crit_dlg_N.vwx.zip
