Hi! I made a rollout like this

try(destroyDialog test001)catch()
rollout test001 "Test"
(
group "Make things:"
(
button mkbox "make box" width:100
button mkcircle "make circle" width: 100
button mkstar "make start" width: 100
button deleteSpObj "deleteSlpineObj" width: 90
)

on mkbox pressed do
(
b1=box()
)
on mkcircle pressed do
(
c1=circle()
)
on mkstar pressed do
(
s1=star()
)
on deleteSpObj pressed do
(
***????????What should i type here??????????????????????***
)
)
createDialog test001

as you can see, this rollout can make box, circle and star. I want to make a button that only delete spline objects and the box stay in the scene. Just click the "deleteSlpineObj" button once and all spline objects will be gone.

I don't know how to do that. Thanks in advance

not sure that would work, it is better to screen the objects via the superclass shape and remove them!


on deleteSpObj pressed do
(
for o in objects do
(
if superclassof o == shape do delete o
)
)

problematic either way are NURBS curves... they're in the shapes group -and- their superclass is shape.. but it's not a spline shape.

Tinson... gotta wonder, though... do you really want to delete -all- spline shapes in a scene... or only those created through you rollout/interface/tool ?

how about: delete (for o in objects where o.category == #Splines OR o.category == #Extended_Splines OR o.category == #shape collect o) The above will delete all splines and filter out NURBS

i think I want to delete all the spline objects in the scene......no matter which are created from script or by mouse(click and drag).

To everyone:
After reading all the replies, i think "delete shape" is good for now. Frankly, I just started learning max. I just realize there are many ways to delete spline objects according to what LoneRobot and Gravey said. It takes time for me to understand every single word you typed there. I will try those method in the future.

Thanks very much to you all for solving my problem.

Definitly, have you ever noticed the difference of a camera on a spline path or a nurb curve? If you get small jitters with a spline, try a nurb!

But that's all really :)
