Drawing Construction Lines With XLINE Command

July 28, 2009 in AutoCAD, CAD

Sometimes we feel the need to use helping (construction) lines in our drawings. Like vertical lines while drawing cross-sections starting with elevations. The XLINE command helps us in such a situation.
Command: _xline
[Hor/Ver/Ang/Bisect/Offset/]
You can select from the available options by entering the first letter (the ones in capital). You can construct free lines without specifying any [...]

Groupping Objects With GROUP Command

July 24, 2009 in AutoCAD, CAD

You can use a command to group objects together in AutoCAD, using the GROUP command. It will be a lot wiser to use BLOCKs instead, expcept some very very simple occasions. It’s worth mentioning jsut in case it might be useful somtime, somewhere.
Fig.1
The example above has been taken from AutoCAD help files. Say you [...]

Text Fit, can be found under the Express pulldown menu, under the Text. Or alternatively at the command prompt, type-in, TEXTFIT.

text-fitpix2

Command: TEXTFIT
Select Text to stretch or shrink: Use an object selection method
Specify end point or [Start point]: Specify a new end point, or enter S to specify a new start point
Pick new starting point: Specify a new start point
ending point: Specify a new endpoint

Using Drawing Recovery Command

July 22, 2009 in AutoCAD, CAD

I know all of us AutoCAD users, has experienced losing our drawing files when a program system failure unexpectedly came. Or sometimes when a power failure or a software problem happens right in the middle of doing our work. And because it is too sudden, most of the times we haven’t saved our drawings.

So in order to avoid losing much of our work, we tend to use Automatic Save so that even we forgot to save our work, the AutoCAD automatically save it for us, albeit it only saved some of it from the time frame we had set.

Some years ago, when I’m just using the previous version of AutoCAD notably the AutoCAD 2002 (this version has the most program error I had encounter), when this system error unexpectedly happen and the AutoCAD shutdown unexpectedly. I used to look for my automatically saved drawing (drawing.sv$) on temporary folders using the window explorer.

So now if you are using latest version of AutoCAD, just as I am using the not so latest AutoCAD Architecture 2008. Recovering ou drawing is not that so complicated anymore. Because AutoCAD now has this command DRAWING RECOVERY.

drawing_recovery_manager

This command recovered our drawing automatically for us. After a system failure or the AutoCAD program failure unexpectedly came, the Drawing Recovery Windows Manager will open the next time we start AutoCAD session. The Drawing Recovery Windows display the list of all drawing files that were open. However unsaved drawings that are open at the time of an unexpected failure are not tracked by the drawing recevery manager. So it is always safe that we always save our drawing from time to time, even if we had set Automatic Save for file precautions.

If happens that you close the Drawing Recovery Window, before recovering all files tha you want to recover, you can always access Drawing Recovery command at all times by accessing from the Files pulldown menu, then Drawing Utilities, then Drawing Recovery. Or at the command prompt, type DRAWINGRECOVERY.

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.

Object Snap

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.

Creating Regions by using Boundary Command

July 22, 2009 in AutoCAD, CAD

Regions are two-dimensional enclosed areas that have physical properties such as centroids or centers of mass. Two or more existing regions can be combine into a single, complex region to calculate an area.

A region can be created from an bojects that form closed loops. Loops can be a combinations of lines, polylines, circles, arcs, ellipses, elliptical arcs, aand splices. Regions can be used for, applying hatch and shading. Regions can also be used in analyzing properties, such as area by using command Massprop and List. Regions can as well be used in extracting design information, such as centroid.

Boundary dialogue box

There are lot of ways in AutoCAD to create regions,but the easiest way I know of creating regions are by using Boundary command. This command can be found under the Draw pulldown menu. Or at the command prmopt, type Boundary or BO for shortcut. After keying-in Boundary command, a dialogue box will appear, just click the Region or Polyline on Object type, then click Pick points, and the n select the internal point you want to be created as region.

Using Baseline Dimension

July 22, 2009 in AutoCAD, CAD

A multi-faceted object on your drawing, will consumed most of your time dimensioning it, if you don’t know the techniques, or the commands that can be use to dimension it continuosly and automatically.

Just in case you encounter such object in your drawing, you can use the command Baseline Dimension and Continue Dimension. You can find these commands, under Dimension Pulldown menu, or at the Dimension Toolbar. Alternatively at the command prompt, type DIMBASELINE or DIMCONTINUE.

baseline_dimension_toolbar

Baseline Dimension or DIMBASELINE, is a AutoCAD command that creates multiple dimension measured from the same baseline. While Continue Dimension or DIMCONTINUE, is an AutoCAD command that creates a multiple dimension placed end to end. To create a baseline dimension continued dimension you should create first a linear, aligned, or an angular dimension to serve as a starting point, or click any extension line from any existing dimensions from your drawing.

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.
