What is the shortcut key for remove vertex in AutoCAD?

The primary input or "shortcut key" used to remove a vertex in AutoCAD, particularly when editing polylines using grips or within certain commands, is g.

When you select a polyline in AutoCAD and hover over or select a grip point (which often corresponds to a vertex), you are presented with various editing options. One of the standard methods to remove a vertex involves selecting the vertex grip and then using the g command option.

How to Remove a Vertex using the 'g' Input

Based on the reference provided, the action is straightforward once you are in the correct editing context, typically involving a polyline.

Here's how it generally works:

1. Select the Polyline: Start by clicking on the polyline you want to modify. This will display its grips.
2. Hover over the Vertex Grip: Move your cursor over the square grip at the vertex you wish to remove.
3. Access Grip Editing Options: Depending on your settings and the AutoCAD version, hovering might show options, or you might click the grip to activate editing modes (like Stretch, Add Vertex, Convert to Arc).
4. Enter 'g' (Go): While the vertex grip is active or you are in a grip editing mode related to the vertex, enter g on your keyboard and press Enter.

As stated in the reference: "Enter g (Go). The vertex on the polyline is deleted. The vertices on either side of the deleted vertex are joined by a straight polyline segment."

This action effectively removes the selected vertex, and the polyline segments on either side of it are automatically connected by a straight line, simplifying the polyline shape.

Alternative Methods

While 'g' is the specific input mentioned in the reference often tied to grip editing, AutoCAD offers other ways to edit polylines and remove vertices:

• PEDIT Command: The Polyline Edit command (PEDIT) has an Edit Vertex option. Within Edit Vertex, there are further options, including Delete (D), which allows you to move to a vertex and delete it.
• Grip Editing Context Menu: Sometimes, right-clicking after selecting a grip might present a context menu with options like "Remove Vertex".

However, the reference explicitly points to the "g (Go)" input as a method for vertex deletion.

Summary of Vertex Removal Input

Method	Input/Action	Result (as per reference)
Grip Editing (often)	Enter g (Go)	The vertex is deleted, and adjacent segments are joined by a line.
PEDIT (Edit Vertex)	Enter D (Delete)	Deletes the current vertex in the PEDIT vertex editing sequence.

The 'g' input is a quick way to remove a vertex directly via grip editing, aligning with the specific information provided in the reference.
