connect vertex/knots in a shape with 2 splines

Submitted by Ralf on Thu, 2020-01-30 04:25

Hello. Basic question (but i can't find it on the internet)

I have a shape with 2 splines: /sp1v1--sp1v2/ /sp2v1--sp2v2/.

Now i want to connect sp1v2 with sp2v1.
something like this:

select $MyShape
subObjectLevel = 1
splineOps.startConnect (1,2) (2,1)

can someone give me a hit? tnx

follow-up question (i have a

follow-up question (i have a problem selecting things)

GB1 = Rectangle name:"GB1" Length: 1.0 width: 1.0 steps:0 
GB2 = Rectangle name:"GB2" Length: 1.0 width: 1.0 steps:0 
rotate $GB2 (eulerangles 0 0 45)
 
convertToSplineShape $GB1
convertToSplineShape $GB2
addAndWeld $GB1 $GB2 0.0
 
select $GB1
max modify mode
subobjectlevel = 3
setSplineSelection $GB1#(1)
splineOps.startUnion $

It works untill the last line.
But "$GB1#(2)","(3 2)", "the-other-spline" gives me errors.

Can you tell me whats wrong

(I have the book "maxscript essentials", but these essential-syntax things are missing..)

tnx.

damn, sure :))
fresh max versions have shape booleans

if you want to boolean shapes then you're in trouble.

yes, tnx a lot Miauu. my

yes, tnx a lot Miauu.

my shape is complexer as in the startpost, but i think i can adjust your code for that.

AddAndWeld is a global shape operation. It will weld any end knots that are in tolerance distance from each other. You probably better use splineOps.weld to weld only the selected knots
