parametric line equation in vb 2

[avi19]

tell me the code to draw line using parametric equation in vb

Look up the "law curve" topic in the NX help: CAD -> Modeling -> Curve -> Law Curve.

The easiest way to discover code required for NX Modeling tasks is to:

a. Turn on Journal recording.

Pre-Ribbon UI: Tools --> Journal --> Record​

Ribbon UI: Developer (Tab) --> Journal (Group) --> Record (button)​

b. Give your new journal file a name and save it in a convenient location.

c. Perform the NX operation for which you want to create code. (In your case, drawing a line...)

d. Stop the Journal recording.

Pre-Ribbon UI: Tools --> Journal --> Stop Recording​

Ribbon UI: Developer (Tab) --> Journal (Group) --> Stop Recording (button)​

e. Open the journal file, and observe the code.

You can always search for things in the NX Open API Documentation, but just recording a Journal is almost always faster.

Oh... and remember that you can choose to record your Journal in VB, C#, Java, or C++, depending on your programming language of choice. (Tweak this setting in the UI Preferences dialog.)

Does that help?

thank you!!!!!!!!!!

all i want to do is construct a whole geometry(Art Designs) and i want to perform scale , rotate , translate etc operations about a point. please tell me the way to do it. journal recording is the way but i want to make it generalized so having a general code will be better i think.....

Do the NX pattern commands not meet your needs?

Suppose you have a line with parametric equation P(t) = (1 - t)*P0 + t*P1. In other words, your line starts at the point P0 = (x0,y0,z0) and ends at the point P1 = (x1,y1,z1).

The VB code to create (and draw) a line using NX/Open functions is:

Dim p0 As New NXOpen.Point3d(x0,y0,z0)
Dim p1 As New NXOpen.Point3d(x1,y1,z1)
Dim myLine As NXOpen.Line = workPart.Curves.CreateLine(p0, p1)

If you use SNAP functions, it's a bit easier. The VB code is just:

Dim myLine As Snap.NX.Line = Snap.Create.Line(x0,y0,x1,y1)
