Open a .jww file and return a compact summary: version, paper, layer groups with scale (1/N) and layer names/counts, entity counts by type, bounding box (real mm), text sample.

Query entities of a .jww file (real-mm coordinates). Filter by types (line, circle, arc, text, point, solid, dimfigure), layer group lg, layer ly, bbox [min_x,min_y,max_x,max_y], or regex pattern on text. Paginate with limit/offset.

List all text strings of a .jww (room names, dimensions, notes) with position, layer and size.

Render a .jww (or a region of it) to PNG and return the image. bbox = [min_x,min_y,max_x,max_y] in real mm to zoom; lg to show one layer group only. Use this to see the drawing.

Convert a .jww to DXF (AC1024 by default) using ezjww. Returns the output path.

Create (or reset) a named drawing. scale = denominator of the drawing scale (100 for 1/100). paper: A0..A4, 2A..5A, 10m/50m/100m. group_names/layer_names set Jw_cad レイヤグループ名/レイヤ名 (e.g. group_names={'0':'平面図'}, layer_names={'0-1':'壁','0-2':'柱'}).

List saved drawings.

List layer presets usable in drawing_new(preset=...) with their group/layer names and per-type defaults.

Open a scanned drawing (PDF or image) for CAD conversion. Pages are rendered to PNG. Returns page sizes and whether the PDF is vector (CAD-exported → scan_vector_import) or raster (read with scan_view).

List opened scans.

Look at a page or a zoomed region of it (region = [x0,y0,x1,y1] in pixels, or fractions 0..1). A red pixel ruler is drawn so you can report pixel positions for scan_calibrate / placement.

Define how pixels map to real mm. Either p1/p2 (pixels) + distance_mm (a known dimension on the scan), or px_per_mm, or scale= (+paper=A2 for images; PDFs know their physical size). origin_px = pixel that becomes (0,0) mm (default: bottom-left corner).

Convert pixel positions on a calibrated page to real mm (and back with mm_points).

Draw a drawing on top of the scan to check alignment (needs calibration). region_px zooms.

For vector PDFs (exported from CAD): import the page's line work into a drawing as lines (real mm). region_px limits the area. Set lg/ly/lc/lt for the imported lines; tag lets you remove them later.

Text strings embedded in a PDF page with pixel and mm positions (vector PDFs).

Summary of a drawing (counts, layers, bbox).

Add entities to a drawing (batch). Returns the new ids. defaults applies lg/ly/lc/lt to every entity that does not set them. entities: list of objects. Common keys: lg, ly (0-15 or hex "0".."F"), lc (1-9), lt (1-9), tag. {"type":"line","x1","y1","x2","y2"} {"type":"polyline","points":[[x,y],...],"closed":false} {"type":"rect","x","y","w","h","angle":0} (x,y = lower-left) {"type":"circle","cx","cy","r"} {"type":"arc","cx","cy","r","start","end"} (deg, CCW) {"type":"text","x","y","text","height":3,"width":3,"spacing":0,"angle":0,"align":"left|center|right","font"?,"cn"?} height/width/spacing are paper mm (図寸). x,y = baseline anchor (left-bottom unless align). {"type":"point","x","y"} {"type":"dimension","x1","y1","x2","y2","offset":500,"text"?,"text_height":3,"decimals":0} offset = real-mm distance from the measured points to the dimension line (sign = side). {"type":"solid","points":[[x,y]x3or4],"rgb":[r,g,b]?} Architectural (expand to Jw_cad lines/arcs/text): {"type":"wall","points":[[x,y],...],"thickness":150,"closed":false,"core":true,"core_ly":1,"core_extend":300, "openings":[{"at":1000,"width":800,"kind":"door|double_door|sliding|window|fixed|opening","hinge":"start|end","side":"+|-","frame":25}], "opening_lg":3,"opening_ly":0,"opening_lc":1} at = mm along the centre line; side "+" = left of travel {"type":"grid","xs":[0,3640],"ys":[0,2730],"x_labels":["X1","X2"],"y_labels":["Y1","Y2"],"extend":1500,"dims":false} {"type":"column","cx","cy","w":600,"h":600,"angle":0,"hatch":true} {"type":"room","x","y","name":"和室","height":5,"note":"6帖"} {"type":"pipe","points":[[x,y],...],"system":"給水|給湯|排水|通気|ガス|冷媒|ドレン|ダクト|給気|排気","diameter":"25A"} {"type":"equipment","kind":"toilet|sink|washbasin|bath|kitchen|ac_indoor|ac_outdoor|fan|cubicle|tank|elevator|box","x","y","w","h","angle","label"} A drawing created with a preset fills lg/ly/lc per type automatically (see presets_list).

Return entities of a drawing (optionally only those with given ids or tag).

Remove entities by id (or every entity with the given tag). Use clear=true to empty the drawing.

Replace one entity (same id) with new content. Fields not given are taken from the new object only.

Set/rename layer groups, layers and scales of a drawing. group_names={'0':'平面'}, layer_names={'0-1':'壁'}, group_scales={'1':'50'}.

Render a drawing to PNG and return the image (bbox in real mm to zoom).

Export a drawing. format: 'dxf' (open in Jw_cad via ファイル>開く, DXF), 'jwc_temp' (外部変形 text that JWMCP_import.bat feeds into an open Jw_cad drawing), or 'json'. Returns the output path.

Import the entities of a .jww file (optionally filtered by lg/ly/types/bbox) into a drawing so they can be edited, re-exported or sent back to Jw_cad.

Create the exchange folder and the three 外部変形 .bat files (JWMCP_send / send_all / import). exchange = folder on this machine (default ~/JW_MCP_Exchange or $JWMCP_EXCHANGE). win_exchange = the SAME folder as seen from the Windows PC running Jw_cad (e.g. 'G:\マイドライブ\JW_MCP_Exchange'). wait = seconds the .bat waits for a response.

Bridge status: exchange folder, pending jobs from Jw_cad, unconsumed responses.

List jobs sent from Jw_cad (each = one 外部変形 run waiting for a response).

Read one job: scales per layer group, selection range, picked points, write settings, layer names and the selected entities (real mm). Use limit/offset for big selections.

Answer a job: the entities are drawn into the open Jw_cad drawing as soon as the .bat sees the file. Give either entities (see drawing_add schema) or drawing=. delete_selected=true removes the originally selected figures first (replace). notice shows a message in Jw_cad. Coordinates are real mm in the job's layer group scales (gaihen_read → scales).

Cancel a job: Jw_cad reports 未実行 and changes nothing.

Place a drawing (or raw entities) in outbox/IMPORT.txt. The user then runs JWMCP_import.bat inside Jw_cad and the geometry appears in the open drawing with layer/colour/linetype attributes.

Parse any JWC_TEMP.TXT-format file (e.g. one saved manually from Jw_cad) into entities.

Render a job's selected entities to PNG and return the image.
