Function that will allow the user to move the point using mouse

[Tn_Pink]

I am creating edit program.

* object (NurbsCurve) is already existing.

I want to do:

1) Get current location points.

2) Move object (NurbsCurve) point using mouse.

3) Get new location points.

Sample Code:

PROCEDURE EditTest;

VAR

{Location Point}

CurrentStartPtX, CurrentStartPtY, CurrentStartPtZ : REAL;

CurrentEndPtX, CurrentEndPtY, CurrentEndPtZ : REAL;

NewStartPtX, NewStartPtY, NewStartPtZ : REAL;

NewEndPtX, NewEndPtY, NewEndPtZ : REAL;

BEGIN

{Get Current Points}

NurbsGetPt3D(FSActLayer, 0, 0, CurrentStartPtX, CurrentStartPtY, CurrentStartPtZ);

NurbsGetPt3D(FSActLayer, 0, 1, CurrentEndPtX, CurrentEndPtY, CurrentEndPtZ);

{Alert Dialog}

AlrtDialog('Please Modify Object.');

*********************************************************************************

I need function that will allow the user to move the point using mouse.

Do you have any suggestions for what type of FUNCTION to use?

*********************************************************************************

{Get New Points}

NurbsGetPt3D(FSActLayer, 0, 0, NewStartPtX, NewStartPtY, NewStartPtZ);

NurbsGetPt3D(FSActLayer, 0, 1, NewEndPtX, NewEndPtY, NewEndPtZ);

END;

RUN(EditTest);

{End of Code.}

Can someone help me or is it impossible?

Thanks much in advance.

Check out the User Interactive section of the Vectorscript function reference. Depending on how you want the script to operate, the TrackObject, GetPtL, GetPt, GetMouse and/or MouseDown function all offer some ability to get a point on the screen.

Actually since you are working with Nurbs, you probably want to look at GetPt3D or GetPtL3d.

You probably want to start with GetPtL as this one call will get you the X/Y coordinates of two points.

I hope this is a starting point for you.

I think you want to use CallTool with the Reshape tool. http://developer.vectorworks.net/index.php/VS:CallTool Note, 2D Reshape will actually work with NURBS.
