1.4.4 - Offset objects
With offset command, you can create a new object in a certain distance but parallel to the original.
You can use the offset command to offset : Lines, arcs, circles, ellipses, 2d polylines, construction lines, rays, and Splines.
If you offset a line, another similar line is created, on the side you specify for the offset.
If you offset a circle or an arc, a larger or smaller circle or arc is created, depending on which side you specify for the offset.
If you offset a polyline, you will create a polyline parallel to original.
Offset an object by specifying a distance
Begin the offset command via Toolbar icon.
- On Ribbon ► Click Home tab ► Offset panel ►click offset icon (Fig.1.4.4.1).
To offset the rectangle (ABCDA), as shown in Fig. 1.4.4.2, in a distance 60 and outside the original object, ( the units are in mm) :
- Command Line prompt says;">:Specify ofsset distance or [Thtough/Erase/Layer] <Through>: Enter 60 for the offset distance, and press ENTER.
- Command Line prompt says:Select object to offset or [Exit/Undo] <Exit>: Using the mouse ,select rectangle (ABCDA), the rectangle becomes dashed.
- Command line prompt says;">:Specify point on side to offset or [Exit/Multiple/Undo] <Exit>: Specify a point to indicate whether the object is to be offset, inside or outside of the original object ,in your example select a point outside the rectangle (ABCDA), and press ENTER to end the command.
- The offset of the rectangle is drawn as you can see in Fig.1.4.4.2.
-Offset an object through a point
Begin the offset command via Toolbar icon.
- On Ribbon ► Click Home tab►Offset panel ►click offset icon (Fig.1.4.4.1).
To offset the circle r1, as shown in Fig. 1.4.4.3, and through the point P1 :
- Command Line prompt says:Specify ofsset distance or [Thtough/Erase/Layer] <Through>: Enter t to indicate that the offset of the object will pass through a specific point , and press ENTER.
- CommandLine prompt says:Select object to offset or [Exit/Undo] <Exit>: Using the mouse ,select circle (r1), the circle becomes dashed.
- Commandline prompt says:Specify through point or [Exit/Multiple/Undo] <Exit>: Click on point P1 to indicate whether the object is to be offset, and press ENTER to end the command.
- The offset of the circle is drawn as you can see in Fig. 1.4.4.3.
- Create Offset from the edges of a face
Make sure you are in 3D modeling mode (Fig.1.4.4.4).
Begin the offset command via Toolbar icon.
- On Ribbon ► Click Solid tab►Solid Editing panel ►click Offset Edges icon (Fig.1.4.4.4).
You will offset the polyline (ABCDA) of the solid object face, as shown in Fig.1.4.4.5 :
- Command Line prompt says:Select face : Select the face (ABCDA), after the mouse is on the face, it turns to gray.
- Command Line prompt says:Specify through point or [Distance/Corner] : type 10 to specify the offset distance of the new polyline (A1B1C1D1A1) from the original polyline (ABCDA). You can, instead of typing the distance value, to select with your mouse a through point for the new polyline, and press ENTER to end the command.
- The offset of the (ABCDA) is drawn as you can see in Fig. 1.4.4.5 .
