SolidWorks MCP

Switch which open document is the active one. Matches the argument against open documents by title, full path, or file name (case-insensitive), calls ``ActivateDoc3``, and reads the active document back to confirm the switch took.

Add an annotation such as a note, balloon, or surface symbol. Places annotation text in a drawing with optional font size, leader attachment, and title-block style metadata fields.

Add an arc to the current sketch. Creates a circular arc defined by center point, start point, and end point. Arcs are essential for creating rounded corners, curved transitions, and complex curved profiles in mechanical designs.

Add a centerline to the current sketch. Creates a construction/reference line that serves as a centerline for symmetrical features, revolution axes, or construction geometry. Centerlines are non-geometric entities used for reference only.

Add an equal-distance chamfer to selected edges of the current model. Chamfers the specified named edges with the given distance. Edge names use the SolidWorks convention, e.g. 'Edge<1>', or you can leave edge_names empty to chamfer all edges if the adapter supports it.

Add a circle to the current sketch.

Add a datum feature symbol (A, B, C, ...) on a drawing edge.

Add a dimension to the current drawing. Creates dimensional annotations on drawing views including linear, radial, angular, and diameter dimensions. Essential for manufacturing specifications and quality control documentation.

Add, update, or remove a drawing view in an existing drawing. Supports configuring the target drawing, view type, parent view, scale, and placement coordinates for common drawing view workflows.

Add an ellipse to the current sketch. Creates an elliptical entity with specified center and major/minor axes. Ellipses are useful for creating oval holes, ergonomic profiles, and complex curved features in mechanical and industrial design.

Add a fillet (rounded edge) to selected edges of the current model. Rounds the specified named edges with the given radius. Edge names use the SolidWorks convention, e.g. 'Edge<1>', or you can leave edge_names empty to fillet all edges if the adapter supports it.

Add a GD&T feature control frame, e.g. position Ø0.2 (M) to A|B|C.

Add a line to the current sketch. Adds a line segment between two points in the active sketch. Lines are fundamental sketch entities used for creating profiles, construction geometry, and complex shapes.

Mate two components in the active assembly. Positions components relative to one another — coincident planes to stack or align them, concentric to line up axes, distance to hold a gap. Entities are selected by feature name, so only each component's reference planes and axes can be mated. Mating to a specific face or edge needs entity names this adapter cannot enumerate.

Add a note or annotation to the current drawing. Creates text annotations, callouts, and notes on drawings for specifications, instructions, and additional manufacturing information. Essential for comprehensive technical documentation.

Add a regular polygon to the current sketch. Creates a regular polygon with specified number of sides, center point, and circumscribed radius. Polygons are useful for creating hexagonal nuts, octagonal features, and other multi-sided geometric shapes.

Add a rectangle to the current sketch. Creates a rectangular profile defined by two opposite corner points, automatically generating four connected line segments forming a closed rectangle suitable for extrusion or other 3D operations.

Add a geometric constraint/relation between sketch entities. Creates geometric relationships between sketch entities such as parallel, perpendicular, tangent, coincident, etc. Essential for creating fully defined, parametric sketches that maintain design intent.

Add a dimension to sketch entities. Creates dimensional constraints that control the size of sketch entities. Dimensions are essential for creating precise, parametric designs that can be easily modified and maintain manufacturing tolerances. In live SolidWorks automation, sketch dimensions can otherwise trigger the interactive ``Modify`` approval dialog. The adapter suppresses the relevant sketch-input preferences for the automation session and uses the dedicated radial/diameter APIs for circles and arcs so this tool remains non-interactive.

Add a spline curve to the current sketch. Creates a smooth, free-form spline curve that passes through or near the specified control points. Splines are ideal for creating organic shapes, complex profiles, and smooth transitions in industrial design.

Analyze drawing annotations and notes quality.

Handle analyze drawing comprehensive.

Analyze dimensions in a SolidWorks drawing for consistency and completeness. This tool performs detailed dimensional analysis including precision, tolerances, and completeness checking.

Analyze drawing views arrangement and quality.

Handle analyze geometry. This tool provides various geometry analysis capabilities like curvature analysis, draft analysis, thickness analysis, etc.

Analyze a macro for complexity, dependencies, and optimization opportunities. This tool provides insights into macro structure and performance to help with optimization and maintenance.

Apply a template to an existing SolidWorks model. This tool applies saved template settings including properties, dimensions, and formatting to the target model.

Move drawing dimensions so nothing overlaps, then check the real result. Dimensions go outside their views in rows (first 8 mm from the outline, rows 7 mm apart, columns 9 mm apart), shortest span nearest the view, each on the side its extension lines start from. One with no room on that side stays put and is listed in ``unplaced``. After moving them it re-reads every dimension's real text box and lines and checks the whole sheet: no text on text, no line through text, no line across another view or across its own view, nothing on a view or outside the sheet.

Auto-insert centre marks on circular features in a drawing view. Runs SolidWorks' automatic centre-mark insertion for the named view. The API does not report how many marks it added, so the response gives the view's centre-mark count before and after and the delta. A run that added nothing is still a success — the view may have no un-marked holes.

Automatically dimension a drawing view. Analyzes drawing view geometry and automatically adds common dimensions including overall sizes, hole diameters, radii, and critical features. Accelerates drawing completion and ensures comprehensive dimensioning coverage.

Start recording a macro in SolidWorks. Begins macro recording to capture user actions and generate reusable automation scripts.

Stop recording the current macro. This tool stops the active macro recording and saves the recorded actions as a VBA macro.

Apply template to multiple models in batch. This tool processes multiple SolidWorks files and applies the same template configuration to all matching files.

Handle batch execute macros. This tool allows running multiple macros in sequence or parallel for complex automated workflows.

Batch export multiple SolidWorks files to a target format. Processes entire directories of SolidWorks files and converts them to specified target formats. Essential for project migrations, supplier deliverables, and large-scale format conversions.

Run a file operation across multiple files as a batch workflow. Intended for repetitive file management tasks such as copying, moving, renaming, or deleting groups of SolidWorks documents.

Handle batch process files. This tool processes multiple files in a directory, performing operations like rebuild, save as, export, or property updates.

Get mass properties of the current SolidWorks model. Calculates and returns comprehensive mass properties for the active model including volume, surface area, mass, center of mass, and moments of inertia. Essential for engineering analysis, weight calculations, and structural design.

Check drawing compliance with company standards.

Check the current drawing against drafting standards. Validates drawing compliance with industry drafting standards including ANSI Y14.5, ISO 128, and DIN standards. Identifies non-compliance issues and provides recommendations for improvement.

Check for interference between components in an assembly. Analyzes specified components for geometric interference (overlapping volumes) and provides detailed interference detection results. Critical for assembly validation and identifying design conflicts before manufacturing.

Check whether a sketch is fully defined.

Classify the active model into a feature family from model-info and tree data. This is a read-before-write helper for delegation. It summarizes whether the current document looks like a direct-MCP solid, sheet metal workflow, advanced VBA-backed part, assembly, drawing, or an insufficient-evidence case.

Close the current SolidWorks model. Closes the currently active SolidWorks document with an option to save changes before closing. This is essential for proper model lifecycle management and preventing data loss.

Compare different versions of drawing files.

Compare two templates and generate difference report. This tool analyzes differences between templates to help understand variations in formatting and properties.

Convert a SolidWorks file from one format to another. Supports exporting source files to target formats such as STEP, IGES, STL, PDF, or other adapter-supported conversion outputs.

Create a new SolidWorks assembly document. Creates a new SolidWorks assembly document from ``template`` (a .asmdot path) or, without one, the default assembly template. The new assembly becomes the active document and is ready for component insertion, mating, and assembly-level operations.

Create a reference axis along a principal direction. Builds an axis from the intersection of two built-in planes: x from Top + Front, y from Front + Right, z from Top + Right.

Cut material from a sketch profile in the active model. Creates a Cut-Extrude feature (Insert > Cut > Extrude). Use this after exit_sketch when you want to remove material — e.g. to create windows, holes, slots, or any through/blind cut in an existing solid body. Sketch selection is never a silent guess: pass ``sketch_name`` explicitly whenever you're not certain which sketch this should act on (e.g. more than one sketch could be unconsumed, or other tool calls ran in between). If omitted, only the sketch most recently created/exited in this same session is used, and only when it still exists in the model — there is no further fallback. Any ambiguity or mismatch is reported back as an error naming the sketch(es) actually found in the model, rather than cutting the wrong profile. Direction: a one-way cut (Blind or ThroughAll) goes along the sketch plane's normal. From a sketch on a face, or on a plane that touches the body only on one side (e.g. a Top Plane sketch under a block extruded up from it), that can point away from the material. The tool then cuts the other way and returns ``cut_extrude.direction_flipped: true``, so you don't need to guess ``reverse_direction``. For a sketch on a plane through the middle of the body, use ``ThroughAllBoth`` (or ``ThroughAll`` with ``both_directions``) to cut both sides.
