Hi Ying,

Unless I have missunderstood the question, the way you scale a Polygon Object isn’t different whether you are in mixed- or pure non-sequential mode.

A Polygon Object is defined by its vertices that are describe in the *.POB file. If you open the Prism45.POB file with a text editor, this is what it reads:

! A 45-45-90 prism with no mirror side
! FSI Dec 18, 1998

C 1 "Splitter surface"

! front face vertices
V 1 -1 -1 0
V 2  1 -1 0
V 3  1  1 0
V 4 -1  1 0

! back face vertices
V 5 -1  1 2
V 6  1  1 2

! Front face rectangle
R 1 2 3 4 0 0

! Top face rectangle
R 4 3 6 5 0 0

! Bottom rectangle
R 1 2 6 5 0 1

! left side triangle
T 1 4 5 0 0

! right side triangle
T 3 2 6 0 0

The syntax used in this file is documented in the Help File under:

The Setup Tab > Editors Group (Setup Tab) > Non-sequential Component Editor > Non-sequential Geometry Objects > Polygon Object 

Briefly, you can view from the front face vertices that the front face is a rectangle whose corners are (-1, -1), (1, -1), (1, 1), and (-1, 1) in X and Y (column 3 and 4). It is a 2 x 2 rectangle aligned with X and Y.

The only size you can change in a Polygon Object is the scaling and it applies to all dimensions. If you want the front face to become 8 x 8, you need to change the Scale parameter of the Polygon Object in the Non-Sequential Component Editor to 4.

Let me know if this answers your question, and take care,

David
