Check server and Visio connection health.

Create a new blank Visio document; page is scaled 1:1 so coordinates are inches. Returns the document name.

Open an existing Visio document (.vsdx).

Save the current document (optionally to a new path).

Close the current document.

List pages in the current document.

Add a new page and select it.

Select a page by name.

List Visio stencil files (.vss/.vssx/.vssm) found in the configured stencil directories (VISIO_MCP_STENCIL_DIRS) or in directory.

Open a stencil file. If the file is locked by another Visio session, a temporary copy is opened instead. Returns a stencil key for drop_master.

List all masters (symbols) in a stencil file, with shape counts.

Drop a stencil master at (x, y) in inches. Returns shape_id.

Draw an orthogonal polyline through a list of [x, y] points (inches). Each consecutive pair becomes a straight segment. Returns shape ids.

Add a centered text label (borderless, transparent) at (x, y).

Place a solid junction dot at (x, y) for >=3-wire nodes.

Set LineWeight (e.g. '1.5 pt') on a shape and its sub-shapes.

Delete a shape by id.

Find the first shape whose text contains text.

List all shapes on the current page: id, master, text, position.

Export the current page to a file. fmt: png, jpg, gif, bmp, tif, svg, emf, pdf, vsdx. Returns the written path.

List stencil masters with measured pin geometry available.

Absolute page coordinate (inches) of a symbol pin, based on measured geometry. Example: pin_point('NMOS1', 4.3, 6.0, 'gate') -> [4.049, 6.0]. Use the result as the endpoint of draw_wire so wires land on pins.

Absolute ink bounding box of a symbol body (inches) for clearance checks — keep wires out of it.
