签名

工 务 局：

object.RoundDistance

对象

类型：暗对齐，暗弧长度，暗径，暗坐标，暗径，暗径大，暗心旋转

此属性适用的对象。

属性值

只读：不

类型：双

一个正实数，表示要舍入距离的值。初始值为 0.00。

言论

此属性将所有尺寸标注距离舍入为指定值。例如，如果此属性设置为 0.25，则距离将舍入到最接近的 0.25 单位。如果将此属性设置为 1.0，则维度的距离将舍入到最接近的整数。请注意，在小数点后编辑的位数取决于属性或 DIMDEC 系统变量设置的精度。此属性不适用于角度尺寸。PrimaryUnitsPrecision

    ' uses RoundDistance to set the unit display
