How to Hide/Unhide Command Line

Sometimes while doing our job in AutoCAD there is some instances that happens unexpectedly. And one of that is the accidental turning off of the command line, and with that, you are unable to see the command that you’re keying-in.

There is two way actually to hide the command window of AutoCAD or in these case to unhide.  One of these is on the keyboard shortcut, by pressing CTRL+9. The other is at the Tools pulldown menu, then Command Line (fig.1). Alternatively if you are using AutoCAD Architecture 2008 and beyond, you can find the command line in Window pulldown menu as well (fig.2).

Thats all for now.

Using REFEDIT Command

REFEDIT or Reference Edit, is a command that modify blocks and external references  or Xref, and redefine block definitions within the current drawing. So if there something you want to modify, some portions of the blocks or external reference from your drawing. Then REFEDIT is the command you can always trust in doing so.

By editing the Block or Xref in place, you can modify the reference within the visual context of your drawing. With REFEDIT you can modify the external reference, without going back and fourth between the reference itself and to you drawing, where the Xref was currently inserted. Therefore, making your life more easier in  doing your work, or for this case editing some portions on your drawing.

The downside in using in-place reference editing of Xref is, it can increase the size of your current drawing files significantly during the in-place editing session. Making your drawing file size more bigger than you expected to be. So even if it is useful for us AutoCAD users, the in-place editing of the external reference or Xref, it is not advisable to do it, only if you are concern about the file size of your drawing. While Xref, has this small issue regarding the file size, the block reference doesn’t have this same issue, making the block more suitable from using the in-place editing or the REFEDIT.

You can access, Edit Reference In-Place or REFEDIT command, by clicking the Tools pulldown menu, then Xref And Block In-Place Editing, then Edit-Reference In-Place (fig.1). Alternatively, at the command prompt, type REFEDIT. Then from within the drawing, select the block or external reference that you would like to modify. Thenafter selectiong the block or Xref a Reference Edit dialog box will appear (fig.2), in the Reference Edit dialog box, select the specific reference that you want to edit.

After selecting the specific reference the REFEDIT toolbox will appear (fig.3), then from there you can save it after you finish editing th object reference in your drawing. The object in the working set are saved to the reference and the Xref or the Block is updated. All Blocks that inserted in the drawing withthe same names as the block that has been modified, will also be updated.

Creating Regions by using Boundary Command

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.

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.

How to Add Breakline Symbol in Dimension Line

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 Dimensions.

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

Jogged Linear Dimension

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.

How to Change Dimension Text in AutoCAD

While doing some visitor tracking in this CAD blog, I came across with a search query “how to change dimension text” in this site’s referral url. Which makes me wonder, what does the searcher really need to know, when he/she makes that search. Is the searcher wants to change the Text content of the dimension or was he/she wants to change te properties of the text in the dimension?.

fig.1

Anyway, changing dimension text is easy. The simplest way to do it is to use the command DDEDIT or ED in shortcut form when you type it at the command prompt. Then edit the dimension text,  just like the way you edit the regular text in your drawing. That is only if you want to replace the content of dimension text. But if you want to change the location of dimension text, or rotate the dimension text from it’s original position. You can use the command DIMEDIT or in the dimension toolbar click the Dimension Edit icon (fig.1). Then a list of options will appear at the command prompt, asking you what will you do next.

How to make a Break-Line Symbol in AutoCAD the Easy Way

I don’t know if this cool AutoCAD routine called Break-Line, in Express tools was already around in the previous version of AutoCAD. Because I haven’t saw this in the previous version of AutoCAD that I’m using, the AutoCAD 2004. It is only just this year that I’d use AutoCAD Architecture 2008, so I have no idea if, whether ther was a already Break-Line Symbol exists, or maybe I just to busy to notice its existence? hhmmm.

Easiest Way of Changing a Text in AutoCAD

I don’t know about the other advance users of AutoCAD if they using FIND command frequently, or if they ever use it at all. Because for me FIND command is one of the frequently used command in AutoCAD. Specially when the drawing I’m working with has a need to replace a series of text annotations.

How to modify a Viewport

Sometimes, you want to modify your viewport in your drawing, you want to redefined it from a simple rectangular shape to any irregular shapes. Well you can always modify the boundary of your layout viewport, just by using the command VPCLIP. And you can find it at the Modify pulldown menu, under Clip, then viewport. Or just type VPCLIP at the command prompt.

Automatic save

As an AutoCAD user for some period of time now, I have encountered so many problems involving data losses, data corruption and damaged drawing files. Which trigger when the AutoCAD that I am using encountered a program error, system error or a windows manager failure. And to some point an, unnoticed power failure.

Usually when I encountered this, the first thing that comes to my mind is the questions, what will happen with the data that I am working on? will it be loss? or can I recover it without any damaged at all?. Especially when times I forgotten to save it.

So to lessen the data losses and damaged drawing due to the above said, I always see to it that I didn’t left uncheck the Automatic save preference box, and set at least 10 minutes to 20 minutes save interval. This option always make a back up copy of the file at your own specific interval. And this also saves me from worrying that I might don’t have any back up data at all.

You’l find this under the tool menu, or just type options at the command prompt.

 

I also remember when I encountered such problem, when I was still barely new on using the AutoCAD. The sudden power failure we had then, loss all my updated drawing files that I had worked for an hour. That incident, serves as a reminder for me to always save my drawing from time to time, and the important of Automatic save (autosave) option and always make a back up copy if necessary.
