HELP with wlax-invoke-method

[Tomislav]

Hello, i need help with following line

 

(setq intersection(vlax-invoke-method vla_obj_first.IntersectWith(vla_obj_second, acExtendOtherEntity)))

 

i keep getting 'no function definition: VLA_OBJ_SECOND'...

of course i have converted two selected lines in vla objects; vla_obj_first and second, before calling that line...

thanx

Try

(setq intersection (vlax-invoke-method vla_obj_first 'IntersectWith vla_obj_second acExtendOtherEntity))

that seems to work, but i added this

 

(setq intersection (vlax-safearray->list
                    (vlax-invoke-method vla_obj_first 'IntersectWith vla_obj_second acExtendOtherEntity)))
 (princ  intersection)

 

to list that point, but i get 'bad argument type: safearrayp #'

how to list it?

[hmsilva]

(princ (vlax-safearray->list (vlax-variant-value intersection)))

 

 

EDIT:

Tomislav,

using,

(setq intersection (vlax-invoke vla_obj_first 'IntersectWith vla_obj_second acExtendOtherEntity))

will return a normal point list or nil if no intersection found...

I FOUND IT

 

(setq intersection (vlax-safearray->list(vlax-variant-value
                    (vlax-invoke-method vla_obj_first 'IntersectWith vla_obj_second acExtendOtherEntity))))
 (princ  intersection)
