# point set in sketch?

Genius

Is there any easy way to create point set in sketch? For example, five points uniformly on a line, an arc or a spline. Thanks!

I would suggest for you to define the first point and curve within the sketch, exit the sketch and then use pattern geometry to  define the rest of the points using the 'along' layout option.

Hi @Abeinjapan   Thanks for your soluton! There seems to be no other choice but to create sophisticated contraints to build point set within sketch.

That would be a feature within feature and it is not possible. Create arcs/splines with constraints in sketch and exit sketcher. Now you can use 'Point Set' command with option 'Equal Arc Length'.

I don't agree with you on "That would be a feature within feature and it is not possible." In fact there are so many features within the Sketch feature, like Offset, Project, Mirror, Insersection, Fillet, Chamfer ...

Well my statement is particular with your question. Commands/functions you mentioned are available with respect to the sketcher environment. May be someone else can explain the consequences having such architecture (feature within a feature). If you feel that such fucntionality should be there then you can raise ER for the same.

Those are not 'features', they are Constraints and are 'resolved' using mathematical techniques for solving simultaneous equations.  Features are hierarchical and are 'solved' sequentially.  Another way of putting it is that inside a sketch the order in which Objects, Constraints, Dimensions, etc are created is irrelevant when it comes to how their relationships are resolved.  Features on the other hand, must be resolved/updated in the order in which they appear in the model's history tree.

Maybe this will help; If it were possible to place a Feature inside a Sketch, then you would be able to add more than one, correct?  And so if that was allowed, when the Sketch updated, since all Constraints will be solved in one mathematical operation, how would it know which Feature to update first, which would be next, etc.

Sorry, putting Features inside of other Features, particularly a Sketch, is just not possible.  The math doesn't work, period.

Hi @JohnRBaker   Thanks a lot for the elaborate explanation of the difference between a feature and a constraint!

@JohnRBaker Nice to hear from you (always ). How are you?

@surfactant there should not be anymore doubts/questions
