請問一下如何得到圖元的massprop的屬性?

phonixs

比如说我创了一个region.


需要得到他massprop里的几个属性值


分别是


moment of inertia


centroid


Area


Bounding box


请问用lisp如何实现?

alin

(setq obj (vlax-ename->vla-object (car (entsel "Select the region: ")))) (vla-get-MomentOfInertia obj)
(vla-get-area obj)
(vla-get-centroid obj)
(vla-getboundingbox obj 'LL 'UR)
