Using Object Snap (Osnap)

July 22, 2009 in AutoCAD, CAD

Object Snap or Osnap for short, is an AutoCAD command primarily use to specify precise locations on objects, from your drawing. Therefore this command works to make your drawing more accurate and reliable. For example, you can use an object snap to draw a line to the center of a circle, or to the midpoint or endpoint of any polyline segment.

Object Snap Toolbar

By default, a marker and a tooltip are displayed whenever you move the cursor over an object in your drawing. And from there you can specify a point, when AutoCAD prompt you for a point. To specify an Osnap at a prompt for a point, you can press SHIFT, and right click to display the Object Snap shortcut menu list. Or click an Object Snap button on the Object Snap toolbar. Or you can just key-in the name of an Object Snap at the command prompt. Just remember that Object Snap works only when AutoCAD ask you for a point, from any command that’s in effect. An error message will be displayed if you try to use an Osnap at the command prompt.

Importance of Object Snap

So, what’s the importance of Object Snap? a question that every AutoCAD users should ask. Object Snap or Osnap is essential to us AutoCAD users, for this function helps us makes our drawing more reliable, more accurate and exact, when it comes to doing our work we’ve been assigned to. Without Osnap in AutoCAD, or without knowing how to use this function your drawing will be more likely as a drawing without a real information.

How to Add Breakline Symbol in Dimension Line

July 22, 2009 in AutoCAD, CAD

How to add a breakline symbol to a dimension line?, that’s the question. Sometimes in a AutoCAD Draftsman’s career, they will encounter such drawing that has an object that needs to be shown with breakline symbol in order to fit the drawing inside the drawing area. And ofcourse a drawing cannot be called as a working drawing if the drawing has no Annotations, Title, and specially if no Dimensisons.

In a drawing that has an object that shown with breakline symbol, it is recommended that it must come up also with a dimensioning with a breakline symbol or jog symbol. And that’s the time, the command DIMJOGLINE will be needed. You can find the DIMJOGLINE command at the Dimension Toolbar, or at the Dimension pulldown menu, Jogged Linear. Alternatively, you can just type DIMJOGLINE at the command prompt.

dim-toolbar-jog

DIMJOGLINE is an AutoCAD command that can create a breakline symbol like object, that can be use in a linear dimension line. Jog symbol are used to represent a dimension value that does not the actual measurement of an object. Typically, the actual measurement value of the dimension is smaller than the displayed value. Once you already made the JOG symbol you can modify it’s position by using GRIPS.
