schdoc_insert_dblib_style

Load a generic two-pin resistor symbol from an existing schematic library, place several resistor components into a blank schematic, and inject the parameters and footprint assignments that would normally be resolved by a database-backed library flow.

This example shows the canonical public path for DBLib-style placement:

  1. load a generic source symbol from R_2P.Schlib
  2. load a blank schematic with AltiumSchDoc(...)
  3. place each resistor with AltiumSchDoc.add_component_from_library(...)
  4. add resolved value, manufacturer, part-number, and sourcing parameters
  5. add the resolved PCB footprint implementation
  6. create a .PrjPcb that includes the generated .SchDoc and .PcbLib
  7. persist the schematic with AltiumSchDoc.save(...)

What It Shows

  1. reusing one generic R_2P resistor symbol for multiple components
  2. keeping DB-resolved symbol, footprint model, and footprint library names in the application row data
  3. passing schematic placement coordinates separately from DB row data
  4. placing components from a .Schlib file with public mil coordinates
  5. adding DB-resolved component parameters after placement
  6. using Description to populate the component description field
  7. adding a PCB footprint implementation through the placed component API
  8. keeping resistor pin hotspots on the 100 mil schematic grid
  9. using Arial 12 bold designators with =Value comments
  10. creating a project with AltiumPrjPcbBuilder.add_schdoc(...) and AltiumPrjPcbBuilder.add_pcblib(...)

Run

From the project root:

uv run python examples\schdoc_insert_dblib_style\schdoc_insert_dblib_style.py

Input

This sample uses:

examples/assets/schdoc/blank.SchDoc
examples/assets/schlib/R_2P.Schlib
examples/assets/pcblib/R0603_0.55MM_MD.PcbLib

Output

The script writes:

examples/schdoc_insert_dblib_style/output/schdoc_insert_dblib_style.SchDoc
examples/schdoc_insert_dblib_style/output/R0603_0.55MM_MD.PcbLib
examples/schdoc_insert_dblib_style/output/schdoc_insert_dblib_style.PrjPcb

Expected Result

The output schematic should contain three side-by-side R_2P resistor placements. Each placement uses the same generic resistor symbol, has DB-style resolved parameters such as Value, Manufacturer, and Manufacturer Part Number, and references the R0603_0.55MM_MD footprint implementation.

Pin hotspots remain on the 100 mil schematic grid. Designators use Arial 12 bold, and the visible comment field is =Value, so Altium displays the resolved values such as 10kΩ.
