Scheme Options

Scheme Options
Technical Article

Options may be set to modify the behavior of ACIS. An option's value may be a flag (indicating an on/off state), a number (integer or real number), or a string. Options may be set in a Scheme application (such as Scheme AIDE) using the Scheme extension option:set; in the ACIS Test Harness using the command option; or in a C++ application using one of several API functions.

save_version

Action

Sets the ACIS version to be used by the part:save Scheme extension.

Name String

save_version

Scheme

Type	Values	Default
integer	3-digit ACIS version	installed version

Description
The ACIS version controls the save file format. The first digit is the major version number. The second and third digits are the minor version number. For example, version 2.1 is represented as 201, and version 3.0 is represented as 300. The default value is the currently installed version of ACIS. In C++ applications, the API api_save_version is used to set the version.

; save_version ; Create a solid block. (solid:block (position 0 0 0) (position 10 10 10)) ;; #[entity 2 1] ; Save the currently-active part to the named file. (part:save "test") ;; #t ; Set the save_version option to ACIS 5.0. (option:set "save_version" 500) ;; 700 ; Save the solid block again in ACIS 5.0 format. (part:save "test50") ;; #t ; Reset the save_version option to ACIS 6.0. (option:set "save_version" 600) ;; 500
