Like other elements in Blender, curve control points and handles can bemoved, rotated, or scaled as described inBasic Transformations. I would like to scale the curve segments using their pivot points I’m certainly not competent to say definitively what can and can’t be done in Blender.That said, I find it hard to imagine what behavior you expect for curves that aren’t simple segments. Thanks Picto, this is not real case, it is just theoretical modeling question, it should be working for all kind of curves and segments.
Note, if there is only one curve in a Curve object,This operation will create a new Curve object with no control points. Separates curve objects that are made of multiple distinct curves into their own objects. Like other objects, curves have textures spaces which can beedited.

• It is basic behaviour I would expect from any 3d software, so it is not possible in blender?
• Specifies the target spline type.
• Opens a pop-up window showing the name of the active attributeas well as the value of that attribute for the selected pointsFrom there, you assign a new value to a selected attribute across all selected points.
• If only a handle is selected, the full point will be duplicated too.The copy is selected so you can move it to another place.

Converts splines in a curve object between Bézier, NURBS, Poly, and Catmull Rom types.This is a basic conversion, meaning Blender does not preserve the exact shape or the number of control points.For example, converting a NURBS spline to a Bézier spline maps each group of three NURBS control pointsto a single Bézier control point with two handles. This operator duplicates the selected control points,along with the curve segments implicitly selected (if any)… Deletes the selected control points, while the remaining segmentis fitted to the deleted curve by adjusting its handles. Duplicates the selected control points, along with the curve segments implicitly selected (if any).If only a handle is selected, the full point will be duplicated too.The copy is selected so you can move it to another place.

• Blender is so advanced in some directions, in some lacks the basic stuff.
• Is the same Bézier curve open and closed.
• The Spin operator only works for one dimensional surface objects.Its use for curves is currently not possible,the full feature is documented in Surface editing.
• Includes handle information during the conversion process.
• If that’s the case, you can temporarily convert them into objects and scale in edge mode with individual origins pivot.
• When converting a NURBS spline to Bézier, at least six points are required.If the number of points is not a multiple of three, the spline will be truncated.

Extrude Curve and Move¶

The Split operator separates the selected portion of a curve from the rest,creating a new, independent curve segment.This curve can then be moved or altered without affecting the other curve. A Bézier curve can be edited by transforming the locations of both control points and handles.NURBS curve on the other hand have only control points. A curves objects can be edited by transforming the locations of control points. Converts the spline to a poly type.

Transform¶

Blender is so advanced in some directions, in some lacks the basic stuff. So when the curve is bezier is there any other trick? It is possible in blender, but thought it is just one shortcut or button (maybe it is). If that’s the case, you can temporarily convert them into objects and scale in edge mode with individual origins pivot. The percentage of control points to remove. Includes handle information during the conversion process.

Extrude Curve and Move¶

Specifies the target spline type. Extrudes points by duplicating the selected points, which then can be moved,and connecting those points back to the original curve creating a continuous curve. If only a handle is selected, the full point will be duplicated too.The copy is selected so you can move it to another place. The Radius allows you to directly control the width of the extrusion along the “spinal” curve.The radius will be interpolated from point to point (you can check it with the normals).The Radius of the points is set using the Radius transform tool.

Set Curve Type¶

This tool can only decimate Bézier curves. Converts the spline to a NURBS type. Remember that when a 2D curve is closed, it creates a renderable flat face. This means thatAlt-C may actually join two curves instead of closing a single curve! This action only works on the original starting control point or the last control point added.Deleting a segment(s) does not change how the action applies;it still operates only on the starting and last control points. Is the same Bézier curve open and closed.
Your curves all seem to be simple segments. Deletes the segment that connects the selected control points and disconnecting them. The Decimate Curve operator reduces the number of control pointswhile trying to maintain the curves original shape.This operator works similar to its mesh counterpart. When in Edit Mode, you can hide and reveal elements from the display.You can only show or hide control points, as segments are always shown,unless all control points of the connected curve are hidden,in which case the curve is fully hidden.

For more details on spline types, see theSpline Types documentation. The Spin operator only works for one dimensional surface objects.Its use for curves is currently not possible,the full feature is documented in Surface editing. Separates the selected curve geometry into their own curve object. Converts the spline to a Catmull Rom type.

When converting a NURBS spline to Bézier, at least six points are required.If the number of points is not a multiple of three, the spline will be truncated. Controls the width of the extrusion along the “spinal” curve.The radius will be interpolated from point to point (you can check it with the normals).The Radius of the points is set using the Radius transform tool.
The Delete operator can remove Control Points or Segments.Deleting can be used to make curves shorter or simplifysegments by deleting control points in the mid section of a segment. Hello, I would like to scale the curve segments using their pivot points (not the point pivots), how to do this in blender? Converts the spline to a Bézier type.- Poly splines are converted with vector handles.- NURBS or Catmull Rom splines are converted with automatic handles. Mesh snapping also works with curve components.Both control points and their handles will be affected by snapping,except for within itself (other components of the active curve).Snapping works with 2D curves but points will be constrained to the local XY axes.
Like other elements in Blender, control points can be moved, rotated, or scaled as described inBasic Transformations. Here I just wanted quickly flatten all segments on their Y axis, sometimes I need flatten the segments their pivots are in different heights Z axis but keep their original Z positions. I am native in other 3D sofware, still learning, love blender every day more, just sometimes get stuck and expecting the same https://www.jungli-win.nl/ things that I silly think are basic. It is basic behaviour I would expect from any 3d software, so it is not possible in blender?
