Support origin localization, re-build the boundary, isolated island deletion, drawing order and build independent fill pattern and so on;

Drawings Encryption
When modify or save file, you can encrypt the file by imputing password, so can guarantee the security of our customer' drawings.
Encryption algorithm is completely compatible with AutoCAD, namely encryption graphic file of GStarCAD and the AutoCAD may be saved and opened mutually.

Auto Backup and Recovery
Records users' entire drawing process and no necessary to worry about any lost of your work by the unexpected error. Adopt a new vector image format (with the suffix .dwh) originally created by GStarsoft.com, Comparing with the standard .dwg file, automatic and timely backup system greatly increases automatic backup speed, for example when the drawing size is no more than 10M, time for backup is about one second. This prompt backup system achieves real time (e.g. automatically backup every 5 minutes).

In case of accidents, such as power failure or abnormal exit, it will restore to the last.edited drawing, reducing losses to minimum. In addition, users can set how many copies and how long it will be kept. If the user saves wrong drawing after improper operation or delete the drawing by mistake, he can restore the file by inputting file name and the save time.

Drawings Compare
Can make the differences between two drawings clearly.
Old Drawing

New Drawing

Excel Paste Function
Can make form in EXCEL, then import it to GStarCAD as basic entity, so it can bring a lot of benefits to you.

Edit Reference in Place
Provide a set of good solutions, you needn't explode block reference and can refer entities conveniently, also can add or delete block reference entities. So you can upgrade all relevant block references without great changes and increase greatly the efficiency of modification and drawing.

Insert the needed computer and telephone block into the appropriate position.
