               Via/Padstack Methods

Via/Padstack Methods

NewVia(name, start_layer, end_layer, cx, cy, padstack, diameter)

Creates a via in the footprint and returns it as a via object.

Parameters:

Name: Name of the via

Start_layer: Integer id retrieved from GetLayerID

End_layer: Integer id retrieved from GetLayerID

Cx: Center x coordinate

Cy: Center y coordinate

Padstack: Name of the padstack to use. Passing an empty string (“”) will result in “No Pad SMT East” by default.

Diameter: Diameter of the via

Example:

var via = LayoutHost.NewVia(“via_name”, layerID1, layerID2, x, y, “PlanarEMVia”, diameter);

SnapVia(via, to_edge, to_edge_pos, x_off, y_off, rel_angle);

Moves a via to the specified edge position. The target snap point is specified by an edge position with an offset and angle. Associated with the target edge position is a normal (perpendicular to the edge and pointing outwards, or to the right in poly-lines) and a tangent vector (pointing in the direction of the edge). These two vectors define the local coordinate system in which x_off, y_off, and angle are specified.

Parameters:

Via: Specifies the via object to be moved

To_edge: Specifies the target object and edge

To_edge_pos: The target snap point. The via position is snapped to this location, specified as LayoutHost.START, MID, or END (or a value < 0, 0, or > 0).

X_off: An offset along the normal vector for the target edge.

Y_off: An offset along the tangent vector for the target edge.

Rel_angle: An additional rotation (specified as a counter-clockwise rotation in radians) relative to the normal vector for the target edge.

Example:

// Place ‘via’ 1 unit inside edge 2 of ‘rect’

LayoutHost.SnapVia(via, rect.Edge(2), LayoutHost.MID, -1, 0, 0);
