![]() ![]() It should be considered as "entry level". The bell is taken along only as wireframe with no shading. The pieces are moved apart and a planar projection is made. The result can be exported as PDF to be used in Illustrator. The rectangle is only a reference how wide planar area corresponds the whole 360 degrees around the bell: I revolved a simple bell like in Illustrator and wrapped a spiral on it. I skip that subject.ĪDD: Just to show that actual 3D programs have more control than Illustrator I insert an example. Their possibilities are limited by the ability to write the needed transformations in the available programming language. Some graphics programs allow programmable mathematical transformations. But drawing it is easy - only click with the Pen in Illustrator. GIMP has also only manual distorting tools.įorcing a round spiral to straight perpendicular curve segments cannot be made by applying a few click effect in common graphics programs. It's a manual stretching and squeezing process, no automatic forcing into a predefined shape isn't provided. Photoshop users can distort their images by applying Warp or Puppet Warp to their images. But that doesn't make it useless, it's still much more than nothing. Illustrator's 3D was never developed to perfection, It has essentially been the same at least a decade. The result shown after removing the bell.Īs you see, the width of the stroke doesn't stay constant, but varies and there's no way to control it. The spiral was dragged into the symbols collection and selected from there to be used as mapped art. More anchors would make the mapping later very difficult because Illustrator splinters the surface to pieces which all need their own surface images. The curved edge has only 2 anchor points to keep the result simple enough. An example:Ī simple profile to be revolved. The result is predictable when the surface is simple enough. Illustrator's 3D is limited and the user has poor control. But that's manual editing.Īnother method is to map the planar shape onto a surface which is made by using one of 3D effects 1) Extrude & Bevel and 2) Revolve. The envelope can be changed in the fly to mesh and that gives plenty of more control. One can adjust the envelope with the direct selection tool and see the result in the fly. It's fortunately easy because the effect is non-destructive. The only way to get different result is to edit either the distorted shape or the envelope. ![]() There's no parameters to adjust the distortion. It's Object > Envelope Distortion > Make with Top Object. The closed path was used as "top object" when using Illustrators envelope distortion effect. It's a Bezier curve drawn by using the "Pen" The first of them is to use Envelope DistortionĪ closed path. ![]()
