![]() ![]() The newly created vertices are selected.ĥ) Select the 3D cursor as pivot in the lower via. I will model a spiral with 8 segments and a radius of 6 Blender Units (BU) and a distance between two turns of 2 BU.Ģ) In Edit Mode rotate it so it is perpendicular to the X axis.ģ) In Edit Mode move it up 6 BU on the Y axis.Ĥ) Extrude e, cancel ESC. ![]() But be aware that this only pays under certain circumstances (modelled segments, end caps) as it drives your vertex count way up. #WINGS 3D SHELL EXTRUDE HOW TO#Changing the scale of the Empty gives another nice effect.Īs the question asked specifically for a simple tube I will give an explanation how to do this with this technique. You can simply manipulate (or animate) the spiral by moving or rotating the Empty. Position and rotation of the Empty in this example the absolute position is the same as the relative position to the cube. It is worth it when you want a finely decorated but repeating spiral. But this needs exact (but not hard) planning in the design of the object, the angles and distances. In fact you can use this technique for continuous spirals as the array modifier allows merging. Don't forget to set a length in the array modifier, either a fixed count or a fixed length (or relative to the length of a curve). The rotation angle and distance determines the radius and object density of the spiral. Move that Empty up (Z-axis) and away (e.g. You would add an array modifier to the original object which is aligned ( Object Offset) on an Empty. a discontinuous spiral, the array modifier is a nice way to do this. If you want to make a spiral from discrete objects, i.e. ![]()
