Cross can run an intelligent extend/trim to crossing lines/curves by picking two points to define a rectangle window. Objects across the window will be processed: Only lines or curves on active processing layer will be selected. The lines or curves will be erased if they totally lie within the window area.
There are two stand-alone applications defined in Cross: Cross-LineX and Cross-CurveX.
Both Cross-LineX and Cross-CurveX use a same setup dialog and operation steps. The number of lines or curves that Cross can process is between two to four. If less or more lines or curves were selected from the window area, users will be prompted to remove or add so that the program can go on.
In most situations, Cross-CurveX can be the replacement command of Cross-LineX, but Cross-LineX will run more stable and quickly than Cross-CurveX for all pure lines.
There are two important features in Cross:
[*] AutoMerge
Cross will automatically process all selected lines and arcs (by crossing window) and determine if they can be merged or weld each other. Cross will try to merge the lines and arcs together as possible.
This feature is very useful on fixing the broken and super-positioned lines and arcs before running real trim / extend operations. This operation will also help users to remove useless lines and arcs data.
[*] UCS support
Cross can run perfectly on UCS.
