Thanks for your reply.
1. conti operation with fixed step
2. convert to weld locations
do you mean to say, to create a "skip weld" and project the weld points...?
This option is available for people having Continues process license.
What should be the way for people with only spot weld license and not continues license..?
Yes, you need a prd_continuous licence, because you use Continuous Mfg from Curves command and then Project Con. Mfg and finaly you must create Continuous Feature Operation.
I do not know any other way how to simly generate lot of weld points along a curve.
