Create a 2D spline inside a sketch

[CesarAero]

Dear support,

I am trying to create a spline inside a sketch by using create_spline and create_control_point with the following code:

# Create sketch in plane_ZX sketch_3 = sketches.add(plane_ZX) sketch_3.name = "spline" ske2D_3 = sketch_3.open_edition()

# Spline coordinates L=100 ctrl_pt_1 = ske2D_3.create_control_point(-L, L/2) ctrl_pt_2 = ske2D_3.create_control_point(0, L/4) ctrl_pt_3 = ske2D_3.create_control_point(L/2, L)

spline_tuple = (*ctrl_pt_1,*ctrl_pt_2,*ctrl_pt_3) ERROR HERE!

ske2D_3.create_spline(spline_tuple)

# sketch close edition sketch_3.close_edition()

# Update the document document.part.update()

However the spline_tuple that is fed into the create_spline command is not able to contain sketcher_interfaces.control_point_2D.ControlPoint2D type objects.

How could I succesfully pass the points into the spline?

Thank you in advance!

Looks like a bug.

The create_spline class method needs to be rewritten using a VB method. Not sure when I'll get a chance to do that right now.

What exactly are you trying to do at the spline_tuple = (*ctrl_pt_1,*ctrl_pt_2,*ctrl_pt_3)part?

I was trying to create a pytjon tuple since an i_tuple is required as input for the function create_spline(i_poles: tuple)

Just do spline_tuple = (ctrl_pt_1.com_object, ctrl_pt_2.com_object, ctrl_pt_3.com_object) that should work for now :)

Nice. I hadn't looked into this much.

Thanks for this. Great stuff.

[mokrueger]

You're welcome. You could also take a look at my other 2 PRs if you got the time. :)

wow it worked thanks!!

[evereux]

Yeah I saw those, thanks again.

I'm hoping to get these all merged by the end of the week.

@CesarAero after the changes are merged in version 0.6.7, it will work with spline_tuple = (ctrl_pt_1, ctrl_pt_2, ctrl_pt_3). Just so you won't be surprised in the future.

Closing as improvements made by @mokrueger are now in release 0.6.7.
