Construction AutoCAD MCP

Change entity properties by handle (one Undo step): layer (created if missing), color ("bylayer", 1-255, [r,g,b]), linetype, lineweight (mm or "bylayer"), ltscale, transparency %, text (text/mtext/dimension override/leader), height, rotation, closed (polylines), attributes {TAG: value} (blocks).

Zoom/frame the user's view: view=extents (default) or a direction (top, front, iso...); window [[x1,y1],[x2,y2]] or handles frame that area. Changes what the user sees.

Create layers. standard="arch" creates the architectural set (AIA/NCS style, lineweights for monochrome plotting, descriptions in the user's language): S-GRID trục (CENTER), S-GRID-IDEN, S-COLS cột, S-COLS-PATT, S-BEAM dầm (HIDDEN), A-WALL tường cắt 0.5, A-WALL-PATT hatch, A-DOOR cửa đi, A-GLAZ cửa sổ/kính, A-OPEN lỗ mở (HIDDEN), A-FLOR-STRS cầu thang, A-FLOR-LEVL, A-FLOR-PATT, A-FLOR-FIXT TBVS, A-FURN nội thất, A-EQPM, A-ROOF, A-ELEV, A-ELEV-OTLN, A-SECT, A-SECT-PATT, A-HIDD, A-AREA ranh diện tích (no plot), A-ANNO-ROOM, A-ANNO-TEXT, A-ANNO-DIMS, A-ANNO-SYMB, A-ANNO-TTLB khung tên, A-ANNO-VPRT (no plot), X-IMAGE ảnh tham chiếu (no plot), X-REF. layers adds/changes custom layers: {name, color (1-255, [r,g,b], "#rrggbb"), linetype, lineweight (mm), plot, description, transparency %, on, frozen, locked}. Existing layers are kept as they are unless update_existing=true (use that to turn layers on/off, freeze or lock). current sets the current layer.

Set up the drawing for a plot scale 1:scale: units (mm), the text style MCP-ARIAL (TrueType Arial: Vietnamese shows correctly, no "?"), the dimension style MCP-1-<scale> (DIMSCALE=scale, text 2.5 mm on paper above the line, architectural ticks, no decimals, ByLayer colors), a multileader style of the same name, table text in MCP-ARIAL, and LTSCALE=0.4 x scale (PSLTSCALE off). All become current. Call once per drawing scale; draw_plan does it for its own scale.

Preliminary structural calculation (bảng tính kết cấu sơ bộ) of the frame of the plan of draw_plan, for the structural set: the beams of every slab (as draw_structure_plan lays them out) and the ground beams; loads by TCVN 2737:2023 (slab build-ups, live loads by room: rooms 1.5, halls and stairs 3, balconies 2 kPa..., partitions, walls on the beams less their openings, self-weight); slab panels shared out to their beams (two-way trapezoid / triangle, one-way); continuous beams with the live load on all / odd / even spans; bending and shear by TCVN 5574:2018 (αm, ξ ≤ ξR, As, bars; stirrups at the supports and midspan); column loads down to the footings, the column capacity and the footing area for the soil pressure. Drawn as a sheet of tables (materials, slab loads, floor build-up, beams, columns and footings, assumptions) with the sign-off (người tính, kiểm tra, chủ trì kết cấu: name, licence No., signature, date) and the note that a licensed structural engineer checks it, calculates it again and signs it. csv_path writes the tables for Excel. The designed bars and stirrups replace the preliminary ones of draw_beam_schedule (call it afterwards). Defaults (materials, loads, soil pressure, footing, column) are reported as assumed; sizes that fail are listed in warnings.

Edit entities by handle (one Undo step): op=move {vector or from/to}, copy {vector or from/to, count?}, rotate {center, angle}, scale {base, factor}, mirror {from, to (mirror line), keep_original=true}, array_rect {rows, cols, row_spacing, col_spacing}, array_polar {center, count, angle (total, 360), rotate_items}, offset {distance, toward:[x,y] (side) or both_sides}, explode (blocks/polylines/dimensions; block attribute values are kept as text). Returns created handles.

Undo the last AutoCAD step(s) (each tool edit is one step). Undoes whatever is last in AutoCAD, so only use it right after your own edit.

Look at an image file (plan scan, photo, sketch, render; png/jpg/bmp/tif/gif) and return it to Claude, optionally a crop [x0,y0,x1,y1] in original pixels (zoom into details to read dimensions) and a pixel grid with coordinate labels (grid=true or a step in pixels) to read positions for calibration and tracing. Needs AutoCAD with the bridge running.
