I just recently came across about this AutoCAD shortcuts guide in PDF from AutoDESK, which I think will come in handy whether you’re a beginner or an advance user.

### How to reduce AutoCAD file size by using Purge and Audit

How to reduce your AutoCAD file size to a smaller size? that is the predicament an AutoCAD Draftsman and any CAD practitioner alike always face. Recently this question comes back to my attention when a colleague of mine ask me regarding his file becoming so big in size and ask me how to reduce it. Good thing I encountered that same predicament of him many times before, and I can still remember the process on how can an AutoCAD file be reduce.

Reducing AutoCAD file size involve a series of commands and it is not easily to remember the first time, specially if you seldom uses it. That’s why it is important that I should blog about this.

Any how… as the title of this article says, yes you can reduce your AutoCAD file by using command purge and audit.  Here is how..

• First thing is audit your AutoCAD files by typing AUDIT on your command prompt. Then after you audited it click “Save as” and save it in DXF file format and then close without saving it again.

### Creating Hatch without Boundary

Commonly when doing hatch we have to create first its boundary before doing the hatch itself.
That is always the case for me when I’m doing hatch in my drawing.
But doing hatch without boundary is also possible and that is the one I’m going to blog about.

To create hatch without boundary, at the command prompt.

type -HATCH
Enter p to specify Properties.
Enter the name of the pattern. For example, enter earth to specify the “EARTH” pattern.
Specify the Scale and angle for the hatch pattern. For my example I use scale “500” and “45” for the angle.
Enter w to specify Draw Boundary.

[Fig.01]

Enter n to discard the polyline boundary once the hatch area has been defined.
Specify points to define the boundary. Enter C to close the polyline boundary. [ Fig. 01]

Then Press ENTER twice to create the hatch.

[Fig.02]

### Re-positioning the Hatch within the Boundary

Most of the time when we do hatching in our drawing the result is not the exact hatch that we desired within our drawing. So to be able to achieve what we desire, we just have to re-position our existing hatch.

This tutorial I did which I discover, while playing on hatch made the desire task easier.

Select the existing hatch with the boundary [Fig.01]

Select the Hatch.. [Fig.02)

Then while still within the selected HATCH right click and select the Origin Point. [Fig.03]

### Editing Hatch objects using Grips

Last time I blog about the usefulness of the Grips function of AutoCAD, I showed how this simple yet effective component of AutoCAD to be of great help in doing everyday task of an AutoCAD Professionals like me. I showed on that post how in one operation you can perform multiple task and can do multiple command, such as mirror, copy, stretch, move, rotate, etc. With that function imagine how fast you can modify your drawing.

When I wrote that article I’m only using AutoCAD 2008 version, right now I’m using AutoCAD 2014 and I just discover that this Grips function not only do multiple things that I mentioned above, but now, this same Grips function can edit the hatch object as well.

### Missing CTB

ctb

There are two types of plot style tables, the named (STB), and the color-dependent (CTB). The named plot styles can be assigned to an object independent color, while color-dependent plot styles table (ctb) which is the commonly used plot styles (at least in my experience) based on the color of the object.

AutoCAD Professionals and practitioners, encounter some problems from time to time regarding printing / plotting their drawing. One of these problem might be the CTB that went missing, which I encountered recently. This problem will only become one, if you don’t know what to do or if you forgot what AutoCAD command you’re going to use to make that CTB appear again, just like what happen to me that time which I forgot what command I’m going to use to make the CTB appear and complete the task at hand at that time.

Anyway, if this situation happen to anyone, CONVERTPSTYLES is the AutoCAD command that one should use. Just key-in CONVERTPSTYLES
onto your keyboard, then a dialogue box will pop out, just click ok and you’re all set.

### Object removed from selection set

He was wondering why when he was using command copy and selecting an object, he cannot select multiple object, whenever he select another object, the previous object he was selected were removed from the selection set.

After looking to what his doing I found out that it was the case when the PICKADD value is set to 0 (turns off), instead of its default value which is 1 (turn on)

When the value PICKADD set to 0, the objects most recently selected become the selection set. The previously selected objects are removed from selection set. But by pressing SHIFT key on your keyboard while selecting you can add more objects to the selection set.

however the value of PICKADD set to 1, each object selected, either individually or by windowing, is added to the current selection set. To removed object from the selection set press SHIFT, while selecting.

### Missing arial text in polygonal mview

Have you encounter problems in AutoCAD like, when you are zooming out from the paper space in your drawing, the Arial text are visible but when you zooming back in, it does not appear at all in your screen?, but when you move back to model space, the Arial text is there and visible, then worst of all is when you print the drawing, all Arial text does not print at all.

This all happen in a drawing that using a polygonal MVIEW, but in a regular MVIEW
this does not an issue at all.

Anyway, I did some searching from the internet and here is the solution that I found that works with my case.

Go to your desktop, right click at the AutoCAD Icon, click properties, then at the dialog box, click the compatibility panel, then uncheck all check box but check the disable desktop composition, click apply then ok, and relaunch AutoCAD.

### Isometric Dimensioning

Isometric Dimensioning

How to put dimension in an isometric object from a 2D drawing? That is the question I received from one of my colleagues sometimes ago, what my colleagues trying to say is, he’s basically want to put a dimension aligned to the isometric object. At first, I thought it is not possible to put a dimension on a isometric object within a 2d drawing, because prior to that question, I have not done such a thing. Good thing one of our senior colleagues had encounter such a predicament before, and so he teach us how to do it.

Dimensioning an Isometric drawing is easily to forget, specially if you ‘re  not using it frequently because it is not a single command, it is a series of commands composed specifically to do one task. That’s why it is best that I should blog this tutorials.

So here it is.

First, after you have created your isometric object put a dimension by using the command, DIMALIGNED by typing it in the command prompt or click the dimaligned icon.

### Edit Drawings Online using AutoCAD WS

The not so latest innovation on AutoCAD today that I just recently discovered is, the AutoCAD WS. This version of AutoCAD allows the user to open and edit any dwg files using just an internet browser and from any computer even without the actual software installed. AutoCAD WS, can also be use with any android mobile, Iphone, ipad and Ipod touch.
