2D Edit and Modify Tricks

Learn how core 2D edit and modify commands reshape, mirror, offset, split, connect, transform, combine, and duplicate geometry efficiently.

What to notice

The 2D edit tools are not decorative shortcuts. They are the commands that keep a scenic drawing editable after the first line is already on the page: mirror it, reshape it, offset it, split it, connect it, compose it, or repeat it along a path.

The Mirror Tool introduces the editing pattern. Standard mode mirrors the selected object to the other side of the axis, while Duplicate mode leaves the original in place and creates the reflected copy.

The next group of tools changes existing geometry. Reshape moves handles and edges or adds and deletes vertices. Offset creates parallel geometry by distance or by points. Split cuts selected objects by line, point, or trim direction. Connect/Combine extends or joins linework depending on the selected mode.

The Modify menu then becomes the drafting command center: Move, Align/Distribute, Rotate, Scale Objects, Add Surface, Clip Surface, Intersect Surface, Convert to Lines, Compose, Decompose, and Duplicate Along Path.

The workflow

Transform: Use transform commands with intent

Mirror, Move, Rotate, and Scale Objects change existing geometry without redrawing it.

The Mirror Tool mode decides whether the original moves or a duplicate is created.

Reshape: Edit points, edges, offsets, and cuts

Reshape, Offset, Split, and Connect/Combine keep the work inside the object instead of forcing a redraw.

The Tool bar mode is the decision point: handles, edges, vertices, distance, points, line split, point split, trim, connect, or combine.

System: Use Modify commands for controlled drafting systems

Add Surface, Clip Surface, Intersect Surface, Compose, Decompose, and Duplicate Along Path turn simple geometry into controlled 2D drafting.

Duplicate Along Path adds settings for number, distance, offset, centering, and tangency.

Mirror and offset mode choices

Mirror/Offset modes: Mirror and offset mode choices

Choose standard or duplicate mode based on whether the original geometry should remain in place.

  • Move the original.

  • Preserve a duplicate.

  • Choose the Tool bar mode before drawing the mirror or offset line.

Add/Clip/Intersect: Add, Clip, and Intersect Surface workflow

Use overlapping 2D polygons to understand Modify > Add Surface, Clip Surface, and Intersect Surface.

  • Add surfaces

  • Clip surfaces

  • Intersect surfaces

One guiding idea

Drafting gets faster when the tool is chosen by the geometry problem, not by habit.

01 The mode bar is part of the tool

A reliable drafting sequence repeats: select the object, choose the tool, then choose the mode. Mirror has Standard and Duplicate. Reshape has handle, edge, vertex, and delete modes. Offset can duplicate by distance or move by points.

That sequence matters because the icon alone does not define the command. The Tool bar decides whether the drawing moves, duplicates, trims, adds a point, deletes a point, or keeps the original geometry intact.

02 Surface commands use overlapping 2D polygons

Surface commands live in the Modify menu. Add Surface merges selected 2D shapes. Clip Surface removes one selected shape from another. Intersect Surface creates a new shape from the overlapping area.

That workflow belongs to 2D drafting: complex scenic outlines are often easier to make from simple rectangles, circles, arcs, and polygons than from one perfect first drawing.

03 Duplicate Along Path turns repetition into settings

Duplicate Along Path is not just copy and paste. The command can duplicate by number or fixed distance, apply a start offset, center the objects on the path, and control whether the repeated object follows path tangency.

That makes it useful for repeated scenic elements such as posts, bulbs, decorative units, or any object that needs to follow a straight or curved guide.

Quick reference

  • Modifier keys differ by OS and workspace.

  • Connect/Combine should be framed as line and geometry focused, not a universal join-all tool.
