Short description
CookieCutter2 is an AutoCAD and Civil 3D AutoLISP trimming and cleanup utility that uses a closed circle, polyline, ellipse, or spline as a cutting boundary to trim intersecting geometry or erase objects inside or outside the selected area.
Command:
Primary command: CookieCutter2
Shortcut command: CC
Multi-boundary command: CookieCutter2Multi
Multi-boundary shortcut: CC2M
Run CookieCutter2 or CC in the AutoCAD command line to select one closed trimming boundary, choose the side to process, and trim or erase geometry. Run CookieCutter2Multi or CC2M to keep objects inside any of several selected closed boundaries by erasing objects outside their combined areas.
Description:
CookieCutter2 is an AutoCAD and Civil 3D AutoLISP alternative to Express Tools EXTRIM, also known as CookieCutter. It accepts a circle or a closed polyline, ellipse, or spline as the trimming edge, then asks the user to pick the side to trim. Depending on the selected side, the routine can behave like EXTRIM or erase all objects on visible layers inside or outside the boundary.
The routine expands the trimming workflow by processing blocks, hatches, and regions. Intersecting blocks can be exploded recursively, nested block attributes can be converted to text, non-solid hatches and regions can be exploded, and solid hatches can optionally be converted to ANSI31 lines before trimming. Objects that cannot be trimmed are preserved or skipped according to their type.
CookieCutter2 temporarily unlocks locked non-xref layers, traces curved boundary geometry into point lists, detects inside and outside areas, calculates intersections with Visual LISP ActiveX IntersectWith logic, offsets the selected boundary to determine trim points, trims intersecting objects, restores the original view and system variables, relocks layers, and groups the operation inside an AutoCAD undo mark.
The included CookieCutter2Multi command adds a multi-boundary cleanup mode. It accepts several closed boundaries, builds the combined inside and crossing selections, protects the selected boundaries, and erases objects outside all selected areas. This multi-boundary mode performs outside erasing only and does not trim intersecting entities.
Helper function: (if any)
Main helper functions include CC:TraceObject, CC:TracePline, CC:TraceCE, and CC:TraceSpline for boundary tracing; CC:GetInters for ActiveX intersection detection; CC:Inside for point-in-polygon testing; CC:CommandExplode and CC:ExpNestedBlock for block processing; CC:AttributesToText for attribute conversion; CC:UnlockLayers and CC:RelockLayers for layer-state handling; CC:ZoomToPointList and Extents for view control; SortInterPoints for ordered trim points; and the CC2M:TraceObject family for multi-boundary outside-erasing support.
Functionalities:
– Runs the primary CookieCutter2 command with the CC shortcut.
– Accepts a circle or closed polyline, ellipse, or spline as the trimming edge.
– Rejects non-closed, self-intersecting, and unsupported boundary objects.
– Lets the user pick whether the inside or outside side of the boundary should be processed.
– Can erase all objects on visible layers inside or outside the selected boundary.
– Behaves like EXTRIM when the erase-all option is not selected.
– Explodes intersecting blocks and recursively processes nested blocks.
– Converts exploded block attributes into text while preserving key properties.
– Explodes regions and non-solid hatches that intersect the trimming boundary.
– Offers to convert intersecting solid hatches into ANSI31 lines before trimming.
– Ignores true external references and can process bound block content when it is explodable.
– Skips annotation and unsupported entities such as text, mtext, leaders, dimensions, mleaders, tables, solids, traces, and remaining solid hatches.
– Temporarily unlocks locked non-xref layers and relocks them when the command ends.
– Uses an offset boundary and IntersectWith calculations to determine reliable trim locations.
– Sorts multiple intersection points to improve repeated trimming behavior.
– Restores AutoCAD system variables, object visibility, layer locks, and the original view after completion or error.
– Wraps the operation in an AutoCAD undo mark.
– Includes CookieCutter2Multi and CC2M for keeping objects inside any of several closed boundaries by erasing objects outside their combined areas.
Result:
The primary routine trims intersecting drawing objects or erases visible-layer objects on the selected side of one closed boundary. It can break down blocks, hatches, and regions so their supported geometry can be processed. The multi-boundary routine preserves objects inside or crossing any selected boundary and erases objects outside the combined selected areas.
