Some of more importants are here :

• ISO 128       Technical drawings

• ISO 15787   Technical product documentation - Heat-treated ferrous parts - Presentation and indications


Save your work in AutoCAD before your PC makes a crash.

There is no 100 %  guarantee the laptop or PC works regulary.
So in this case how to protect our works,large modifications in projects,a lot of time maybe we are working??? Solution is:

Automatic Saves

You should save your drawing or template immediately after you begin work.Then save every 10 minutes (it is default) or you can change often or rare it depends by you.

Command: savetime
Enter new value for SAVETIME <10>: 

AutoCAD provides an automatic save tool that automatically creates a temporary backup file during a work session.See the figure below you can change the minutes..

As you show the default settings automatically saves every 10 minutes.By default ,AutoCAD names automatically saved files *.sv$ in the C:\Documents and Settings\user\Local Settings\Temp folder    for you I recomande to change this path for easy access this files. Change the path..go to File-->Options-->Files--Automatic Save File Location .. click Browse button as showed below and go to your desired folder..

The Automatic save features is inteded for use in AutoCAD shuts down unexpectedly ect.
By default,the next time you open AutoCAD after a system failure, the Drawing Recovery Manager displays ,containing a node for every file to display all of the available versions of the file:The original file,the recovered file saved at the time of system failure,the automatic save file,and the .bak file..

True mobile CAD is possible. CADO™ is coming soon..

CADO™ is now on Kickstarter to raise funding to complete the development of the app. Be sure to visit the campaign for exclusive offers on CADO™ and lifetime licences!

CADO™ is a new CAD application for the iPad developed by Orange Juice Studios LLP. CADO™ is a fresh take on the drawing needs required on a mobile touchscreen platform. The interface system is a patent pending technology called the OMouse that provides not only an offset cursor for accurate drawing, but also trailing buttons that follow the cursor within an ergonomic distance to allow single handed drawing for the mobile platform. Now you really can draw accurately with one hand whilst holding the tablet with the other hand.

Until now the tablet has not been taken seriously for technical drawing, falling far short of its potential. This is due to perceived shortfalls such as the ability to draw accurately with your finger, sometimes referred to as the ‘fat finger problem’ and the question of its ability to handlelarge amounts of drawing data whilst remaining fluid and responsive. Current applications allow the tablet to be be used for primarily viewing technical drawings andsome provide a measure of editing and mark-up tools, such as revision clouds, text and the ability to draw primitive geometry. Thedrawing experience offered by these applications is often a slow and frustratingone with very little accuracy and hence do not deliver a true CAD experience. The touch screen has not improved matters with the interface being seen as cumbersome and simply not fit for purpose. For these reasons serious drawing on the tablet has not been possible, until now.We feel this hobbled approach to technical drawing is because the current CAD applications are based on legacy software that the incumbent companies are bringing with them to this new platform.

"Caption: The above image is a screen shot of CADO™ illustrating the OMouse being used to draw a straight line. The user is able to confirm or cancel the command by pressing either of the floating buttons that ergonomically trail the offset cursor. The horizontal and vertical guides along with the running dimensions and angles allow the user to draw quickly and intuitively"

Another issue tackled by CADO™ is the speed and drawing experience offered by the application; by employing OpenGL as the primary coding language and optimising it to suit the hardware constraints of the tablet device, CADO™ is able to provide a smooth drawing experience. Even loading a very large amount of data does not affect the performance of the app. The drawing space is also near infinite that will allow the user to draw anything from the solar system to a microchip and anything in-between.

The graphical user interface is intuitive, bespoke and tailored for single-handedoperation, which makes CADO™a drawing program sophisticated enough for professionalswhilst simple enough for the home enthusiast to produce technical drawingsand remaining mobile. Once you are finished with your designs, the drawing may be emailed to another userin either the native file format, or DXF/DWG, for maximumcompatibility with no loss of time and duplication of effort.
