EXAM IN COMPO4

APPLICATION SOFTWARE

How do you DXFIN into an existing drawing?

In the old days of R12/R13, you could be in a drawing full of objects, and do a DXFIN to merge additional objects from a DXF file. But that changed in R14, requiring you to begin a new drawing, DXFIN, saveas a DWG, reopen the original drawing, and insert the newly converted file. Now using AutoCAD 2000, you can once again bring DXF based geometry directly into the existing drawing.
Issue the INSERT command.
Choose the BROWSE button.
Pull down 'Files of Type' and choose *.DXF.
Select your DXF file and choose Open.
Turn on the 'Explode' toggle.
Turn off the rest of the toggles.
Choose OK to complete the operation.
Starting AutoCAD 2000 with no starting drawing!
If you would like to start AutoCAD 2000, but don't want a blank empty drawing, and you are not using the 'Startup Dialog' you can put this in your ACAD.LSP and it'll create this effect.
(defun-q mystartup ()(while (eq 1 (logand 1 (getvar "CMDACTIVE"))))(command "_CLOSE"))
(setq S::STARTUP (append S::STARTUP mystartup))
In LISP code, don't (regapp) until you have to!
It may be tempting to place the (regapp) code at the top of your LISP code so that you won't have any problems adding EED during your application. But doing so changes the status of the DBMOD, and disables the already fragile ability to DXFIN. Place the (regapp) in the specific function that creates/modifies the object, right before the code that actually creates it.
On the subject, its not a bad idea to check to see if its already registered like:
(if (null (tblsearch "APPID" "MYAPPID"))(regapp "MYAPPID"))
How can I change a solid or surface into 3DFACE's?
Using R14 or higher you can issue the 3DSOUT command to create a file, then use 3DSIN to read it back in to create the 3DFACE's.
What are proxyobjects and can I delete them from a drawing?
They are custom objects that require the presence of the application that generated them to be 'fully' functional. Sometimes when the application is absent they will still appear/plot the same but you can't edit them or acquire information about them. Sometimes you might even get a box with an X through it as in the case of the RTEXT object.
The AEC group of Autodesk deserves credit for releasing the recent versions of the Object Enabler. It is free and allows recipients of drawings with their proxies to see and do more with the otherwise impossible representation.
Depending on your situation, saving the drawing in an R12 format (different file name of course) is a brute force approach to purging the drawing of proxies. However depending on whats contained it can have ill effects.


CORELDRAW X3

Using the Blend Tool and Power Clip in CorelDRAW X3In the following tip, you will see how the Blend Tool and the PowerClip tool were used to create a business card and logo for a locksmith service.

1. Select a key shape from the Transportation symbol font (symbol 061).
2. Select the key and convert it to curves (Ctrl+Q) or Arrange/Convert to Curves.
3. Remove the fill from the key and select a heavy (6 - 7 pt) stroke outline color of your choice.
4. Copy and paste the key (Ctrl+C and Ctrl+V, or Edit/Copy and Edit/Paste). Make the stroke on this duplicated key lighter (.2 pt) and make the outline color white.
5. Select the white key, then select the Blend tool and drag to the larger stroked key.
6. Select the Interactive Drop Shadow tool and add a drop shadow to the blended keys.

Outlook Express

Saving Background SoundsIt is possible to save background sounds embedded into email onto your hard disk. Open Tools > Options > Send. Change both Mail sending formats to plain text. Open the message you want to grab the sound from and click on Forward. The sound files will appear attached to the forwarded message. Save the files from here and close the message. you can now reset any HTML settings that you changed.Import messages and address easilyOutlook Express lets you import messages and addresses from other popular mail clients. Click File > Import and choose the appropriate item to import. Follow the instructions on the Outlook Express Import Wizard.Beauty in picturesInstead of sending pictures as attachments, insert the photo directly into the message. this way, the image will not have to be opened separately. Make sure that the recipient can receive HTML messages. To embedded an image into a mail message, while composing a message, click on Insert > Picture and choose the image you wish to insert. The image will be received as part of the message instead of an attachment (depending on the recipient's mail client).

Instruction Sets

- An instruction set is (a list of) all instructions, and all their variations, that a processor can execute.Instructions include:arithmetic such as add and subtractlogic instructions such as and, or, and notdata instructions such as move, input, output, load, and storecontrol flow instructions such as goto, if ... goto, call, and return.· Data Transfer Instruction- When stored in memory the bytes, words, and doublewords in the packed data types are stored in consecutive addresses, with the least significant byte, word, or doubleword being stored in the lowest address and the more significant bytes, words, or doubleword being stored at consecutively higher addresses. The ordering of bytes, words, or doublewords in memory is always little endian: the bytes with the lower addresses are less significant than the bytes with the higher addresses.
