Spline type

If you create Spline using Line Mode, it not toggle spline type. So everytime you want to tweak spline it turns into smoothed spline. To avoid this smoothing you have to change everytime spline type by using command Splyne Type(In visual tools this command called Line List (Check box)).
Very annoying bug. May be it is not bug but this behavior has to be changed.


Also NVil not remember this checked state of Line Mode, so if you restart NVil it will be unchecked.

If you create Spline using Line Mode, it not toggle spline type.

When creating a spline, you can create a spline with a possible mix of smooth segments and line segments. The "Line" option in the spline tool popup, is an option to draw a line segment, not an option to change the entire spline to a "line list" spline.

No, you do not. There are options:- "Edit > options > Spline Transform Options >"

It is not a bug. If it is changed, it will break how splines are created.

Wow, many thanks!

How to insert Sharp point? I can only insert smooth point.
Also how to convert smooth point to sharp?

You should also have a look at:-

That shows example on Using MMB/RMB while creating splines.

Thank you some times I underestimate Help file.
