how to create this block

[师兄]

I want  create a block，a circle and a line in this block,then i insert this block into my document,

i need the normal of circle is pointing current  Z axis of ucs,the endpoint of line is pointing current X axis of ucs(any ucs), but my codes work is not my  effect, any one who see this message can help me?

xvec(1) = xvec(1) + org(1)
xvec(2) = xvec(2) + org(2)
yvec(0) = yvec(0) + org(0)
yvec(1) = yvec(1) + org(1)
yvec(2) = yvec(2) + org(2)

Set ucs = .UserCoordinateSystems.Add(org, xvec, yvec, "123")

.ActiveUCS = ucs

Dim nor As Variant

Set blk = blks.Add(NewPnt3d(0, 0, 0), "1")
Dim cir As AcadCircle
Set cir = blk.AddCircle(NewPnt3d(0, 0, 0), 10)

'cir.Normal = Normal

Dim lne As AcadLine

Dim p2 As Variant

Set lne = blk.AddLine(NewPnt3d(0, 0, 0), NewPnt3d(10, 0, 0))

Dim blkref As AcadBlockReference

Set blkref = .ModelSpace.InsertBlock(NewPnt3d(0, 0, 0), blk.Name, 1, 1, 1, 0)

blkref.TransformBy ucs.GetUCSMatrix
