VB: MathVector

Does anyone know how to create a MathVector for SolidWorks?

I thought it was an arrary of three Doubles
"Dim myVector(3) As Double...", but that doesn't seem to work.

Could anyone help me out?

 

apihelp.chm, select the MathVector topic, check the "accessors" link :
you get MathUtility::CreateVector.

a MathVector is a COM object which contains 3 doubles, but also methods.
Those Math... beasts were introduced in SW2003 only
Many older APIs use variants of 3 doubles instead.

 

I have used:

Dim MathUtil As MathUtility
Dim MathP As MathPoint
Dim MathV0 As MathVector
Dim PointCoords(2) As Double 'Remember that "0" is the first
coordinate so I have 3 values


Set MathUtil = swApp.GetMathUtility
Set MathP = MathUtil.CreatePoint(PointCoords)
Set MathV0 = MathP.ConvertToVector

It is probably not the bedst way, but it was effektive for my purpose.

Philippe,
Sorry for taking so long to reply.
I was wrong above.

Fourth & fourth? It's usually a 3 X 4 matrix. For geometry ...

translation.

Scaling:
"The canonial form of the matrix which scales the units in the
secondary
coordinate system is obtained by multiplying the unit vectors
representing
the secondary axes by the scale factor"(s).

IE,
2,0,0,0
0,2,0,0
0,0,2,0

Each axes can have a different scale applied.

Example:
2,0,0,0
0,3,0,0
0,0,1,0

Hope I got something right <g>. The memory fades ....

 

Thomas,
Thanks a bunch!
That worked perfectly. I'm now able to move parts in my assembly.

Hopefully I'll be able to finish this VB program soon.
