AutoCAD 2009 Tutorial 3 - Understanding the Modify Panel

This AutoCAD 2009 Tutorial is going to help you to learn AutoCAD by clearly explaining the Modify Panel. This AutoCAD Tutorial will show how to edit objects created in a drawing with commands and also by direct object manipulation.

Modify Palette

Move Command

Due to design changes or drawing errors it is often necessary to move an object or group of objects from one drawing location to another.

Copy Command

Instead of redrawing identical or similar objects it is quicker to draw it once and make copies in new locations.

Rotate Command

It is sometimes necessary to change an objects orientation in a drawing. The rotate command changes the angle of objects around a base point.

Stretch Command

The stretch command allows you to resize objects by dragging them and can be used to edit a single object or groups of objects.

Scale Command

Often, the size of an object needs to be changed, either proportionately bigger or proportionately smaller.

Offset Command

The offset command is used to construct a similar object parallel to the original at a specific distance.

Mirror Command

The mirror command creates a mirror image of existing geometry.

Erase Command

While you learn AutoCAD, a natural part of the drawing process is to correct mistakes.

Explode Command

The explode command is used to reduce compound objects such as block insertions, polylines, dimensions, multi lines, hatches, groups, 3D meshes or 3D solids, into individual objects.

Trim Command

Some objects don’t take their shape until after they are edited. Clipping away portions of the objects is part getting the final product.

Extend Command

Objects are extended at the end closest to the point where the object was selected. The end of the object is extended until it intersects with the first selected boundary edge.

Fillet Command

The fillet command connects two objects with an arc of a specified radius without needing to pick the location of the center.

Chamfer Command

Lines and 2D Polylines may be chamfered by connecting the closest endpoints of two objects with a bevelled line.

Break Command

Only the object types line, circle, arc and 2d polyline can be broken. Circles are broken counter clockwise.

Array Command

In one step, multiple copies of an object can be created in a rectangular or circular pattern.

Lengthen Command

The end of the object, closet to the point where the object was selected, is the end that will be lengthened.


In keeping with the theme of this AutoCAD 2009 Tutorial, using grips is an alertnative way to modify objects.
