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.

rem_use_rbi

rem_use_rbi

Action

Controls the method used to remove faces.

Name String

rem_use_rbi

Scheme

Type	Values	Default
boolean	#t,#f	#f

C++

Type	Values	Default
logical	TRUE,FALSE	FALSE

When set to TRUE this option will make api_remove_faces call api_remove_and_repair_body to remove the specified faces, rather than using its own algorithm. Its own algorithm does not utilize remote faces, whereas api_remove_and_repair_body does.

rem_use_rbi ; Control method used to remove faces. (define b1 (solid:block (position -25 -25 -25) (position 25 25 25))) (define b2 (solid:cylinder (position 0 0 0 ) (position 0 0 35) 5)) (solid:subtract b1 b2) ; option off - remove fails (option:set "rem_use_rbi" #f) (define f1 (pick:face (ray (position 0 0 0) (gvector 0 0 -1)) 1)) ; expect Error rem:remove-faces: ; gap cannot be filled (rem:remove-faces f1) ; option on, remove succeeds (roll) (option:set "rem_use_rbi" #t) (define f1 (pick:face (ray (position 0 0 0) (gvector 0 0 -1)) 1 )) (rem:remove-faces f1)
