HI Michael

因为我在老旧电脑中仍需要使用支持32位系统的V3。CurveLengthBeingDrawn快捷键指令使用步骤有些复杂，容易与下一个操作指令重合，我想直接显示曲线长度信息。（Because I still need to use V3 that supports 32-bit systems on my old computer. The steps for using the CurveLongBeingDrawn shortcut command are somewhat complicated and can easily overlap with the next operation command. I want to directly display the curve length information.）

Hi SUIYAN, try setting this up on a shortcut key:

script:var curves = moi.geometryDatabase.getSelectedObjects().getCurves(); if ( curves.length == 1 ) { var crv = curves.item(0); var len = crv.getLength(); moi.ui.alert( moi.ui.formatNumber( len ) ); }

That should pop up a message with the length of the selected curve and it should work on V3.

Thanks Michael
我已将它作为脚本添加到V3中，并结合PointCoordinates、CVolume等脚本，完成了对v4 info——properties功能的大致替代效果。(I have added it as a script to V3 and combined it with scripts such as PointCoordinates and CVolume to achieve a rough replacement effect on the v4 info properties function.)
