AUTOCAD中几个特殊的系统变量(国外英语资料) Several special system variables or commands in AUTOCAD - Here are a few details. 1, MBUTTONPAN system variables The action response of a third button or pulley to a fixed point device. 0 support the menu (.Mnu) file definition action 1 support translation when holding and dragging the button or pulley Default is translation operation. IntelliMouse or other pulley mouse IntelliMouse is a two button mouse with a pulley between two buttons. The function of the left and right buttons is the same as that of the standard mouse. The pulley can be turned or pressed. Instead of any AutoCAD command, you can scale and translate graphics directly using pulleys. By default, the scale is set to 10%; each time the pulley is rotated, the zoom level is changed by 10% increments. The ZOOMFACTOR system variable controls the incremental change in the rotation of the pulley (forward or backward). The greater the value, the greater the increment. The following table lists the AutoCAD actions supported by IntelliMouse. 2, MINSERT command Inserts a block of multiple references into a rectangular array. Blocks inserted with the MINSERT command cannot be broken up. Note: you cannot break the block object with an asterisk in front of the block name as you use the INSERT command during the insertion process. Before specifying the insertion point, the option at the insertion point sets the ratio of the preset block and the rotation angle. Presets are useful for dragging blocks using scale factors and rotation angles other than 1 and 0. Other relevant commands: INSERT, ADCENTER, REFEDIT. 3, XPLODE command Decomposes a composite object into its component objects. A composite object consists of more than one (more than one) AutoCAD object. For example, a block is a composite object. Multiple composite objects can be decomposed at the same time, each color, layer and line of each object are modified, or the whole selection set is modified globally. You can specify color,
