How do I Select a Face of an Editable Mesh by its Index?
A user asked:
Is there a way to select a face in an editable mesh when you only know its index?
Answer:
When doing it just once, you can quickly type in the Listener something like:
This selects the face with index 10 assuming that a single object is selected and
it is an Editable_Mesh.
If you are doing this very often, the following macroScript provides a UI with a spinner
to select the face index and some error handling:
SCRIPT
|
macroScript FaceByIndex category:"MXS Help"
(
global SelectFaceRoll
try (destroyDialog SelectFaceRoll) catch()
rollout SelectFaceRoll "Select Face"
(
spinner face_index "Face Index" type:#integer range:[1,100000000,1]
on face_index changed val do
(
if isValidNode selection[1] and classof selection[1].baseobject == Editable_Mesh do
(
if val <= selection[1].numfaces then
setFaceSelection selection[1] #{val}
else
setFaceSelection selection[1] #{}
)
)
)
max modify mode
try (subObjectLevel = 3) catch()
createDialog SelectFaceRoll 150 30
)--end macro
