AutoCAD Tip: Master Precise Geometry Edits with AutoCAD STRETCH

The STRETCH command is one of AutoCAD’s most useful editing tools because it lets you change an object’s shape while preserving the portions that should remain fixed. Unlike MOVE, which relocates complete objects, STRETCH modifies only the vertices and endpoints captured by a crossing selection.

For professionals preparing plans, details, layouts, or production drawings, precise stretching is a fast way to accommodate design changes without redrawing geometry. For AutoCAD software, training, and workflow resources, visit NOVEDGE’s AutoCAD collection.

Use crossing selections—not regular selections

The key rule is simple: STRETCH affects only objects that are included in a right-to-left crossing window or crossing polygon. Objects completely inside the selection move; objects crossed by the window boundary are stretched at the applicable vertices or endpoints.

• Type STRETCH, or enter S at the Command line.
• Start a crossing selection from right to left.
• Capture only the endpoints, vertices, or portions that need to change.
• Press Enter.
• Specify a base point and then an exact displacement.

A conventional left-to-right window selection will not produce the intended stretching behavior. When precision matters, confirm that the selection area is green, indicating a crossing selection.

Enter exact displacement values

Avoid stretching by eye when the modification has a defined distance. After choosing the base point, enter a relative coordinate such as @24,0 to stretch 24 drawing units horizontally, or @0,-12 to stretch 12 units downward.

• @X,Y defines an exact relative displacement in the current UCS.
• Use Ortho Mode (F8) to constrain movement horizontally or vertically.
• Use Polar Tracking (F10) for controlled movement at specified angles.
• Use Object Snaps to anchor the base point accurately to existing geometry.

For example, if a room must become 18 inches wider, create a right-to-left crossing window around the wall endpoints, dimensions, and related annotation that must shift. Then use a base point on the wall and enter the required displacement. This is usually faster and more reliable than moving objects individually and repairing dimensions afterward.

Know what STRETCH can modify

STRETCH works especially well with lines, polylines, arcs, splines, hatches, and block references, depending on what the crossing selection captures. For polylines, crossed vertices move while uncrossed vertices remain in place. This makes STRETCH ideal for adjusting outlines, wall profiles, site boundaries, and detail geometry.

Be cautious with associative dimensions, hatches, and complex blocks. A properly configured associative dimension may update automatically, but always inspect the result. If a hatch does not update as expected, verify that it is associative and that its boundary remains valid.

A practical precision checklist

• Turn on the object snaps needed for the task.
• Use a crossing selection that includes only intended edit points.
• Enter numerical distances instead of estimating visually.
• Check dimensions and hatch boundaries immediately after the edit.
• Use UNDO promptly if an unintended vertex moves.

Mastering STRETCH helps maintain drawing integrity during revisions. It turns late-stage adjustments into controlled, measurable edits—exactly the kind of workflow improvement that saves time across every AutoCAD project.
