Info Compare the layout of this table "Polygon point data" to table "SHAPEP" above.



For users of Ple4Win's predecessor PLE-micro-CAD. If "As with PLE3" is selected, the keyboard shortcuts of PLE-micro-CAD are implemented as far as possible. Otherwise, the default Windows keyboard shortcuts will be used. Check keyboard shortcuts for the key assignments in each mode.

Click to expand/collapse Ple4Win Options: Data formatting


The option "No formatting" will show all available figures. This option is not recommended since in most cases this layout will not be clear.

Info The value of "Minimum significant figures displayed:" does not apply to this option.



Click to expand


Selecting "Apply scientific notation" will show all values with powers of 10. The "Minimum significant figures displayed:" determines the number of figures.



Click to expand


Engineering notation is a version of scientific notation in which the powers of ten are multiples of three.The number of figures is determined by the smallest absolute value in each column.



Click to expand

Info One can choose to also apply these setting to locked input tables. (Not locked input tables are only available as texts and cannot be formatted, locked tables are also available as values)



Usually a user will use the system separators. However, by unchecking the checkbox "Use system separators" the user can define other characters as separators.

Warning The thousands separator is not included yet.

Click to expand/collapse Ple4Win Options: File system


A Ple4Win.plex project file in a Project folder is extracted in the Work folder. Ple4Win uses these databases in the Work folder as long as the project is open. The.plex database is left unchanged, as long as no data is explicitly saved to it. Also the auto recovery data is saved in the Work folder as well as possible test output files (*.tst).

Info Use the Browse button to change the location of the folder. Pressing the Show button will open the work folder directory.



If this backup option is checked, each time a project is closed a backup of the project is created with the state of the project before opening. The backup file is named ProjectName.pleb. Such a backup project can be opened again by choosing Ple4Backups as file type in the Open Project database dialog (or simply by double clicking on the backup file in Windows Explorer).



A backup is automatically saved in the Work folder every n minutes. This backup will be used to recover  the project after a system crash.



Select this option to show the Recent Projects list. The number of last projects to be displayed in this list can be chosen from 2 to 10.

Click to expand/collapse Ple4Win Options: Advanced


If "Enable  test mode" is checked, a file named Ple4Win.tst is created in the User Application Data Folder. Tracing information is written to this file during the run of the program.

Info Writing to this file is buffered, information may be missing until the program is ended.

The "Test level"  is only available if the test mode is enabled. If the level is set > 0, while opening a pipeline project file, a file with the same name and with an file extension.tst is created in the Work folder. Debug information is written to this file until the project is closed.

Info The test level has to be set prior to opening a pipeline project.

Info Test mode and test level should only be set if requested by a program support technician. Entering test mode significantly slows down the program!

Warning If the test level is set to > 5, massive amounts of debug data will be written!

The "Leave temporarily files ..." option is only available if Test mode is checked. Usually work files (ending with extension.tmp) will be deleted when closing a pipeline project. If  this checkbox is checked, these files are not deleted.

Info Undeleted work files will be overwritten without warning if the project is opened again.



With a rental license the hardware key verifies the date via the Internet. Some (company) firewalls prevent the key to access the internet, causing Ple4Win not to start. If this option is checked, the hardware key will not attempt to get access to the Internet.
