Object To Point Rail earns its place for a narrow, practical job: aligning mesh objects to evenly spaced points along a rail made from edges, with no modifiers involved. The developer built it to reach exact locations that were awkward to get otherwise.
Object To Point Rail is a Blender addon that places mesh objects on a point-rail derived from selected edges. It uses no modifiers, and the rail is not a curve. The total length of the rail is divided by the number of points, so the distance between points measured along the rail is the same everywhere. Rails can run in three dimensions.
You build a rail in edit mode by selecting connected edges that form lines with no branches, then pressing Create Point rail. Points are marked by crosses, with the first labelled start, and a settings menu covers swapping start and end, setting an amount or fixed distances, cross size, and a maximum number of points shown (default 100). With the rail ready, select a mesh object at the start and press Objects to points to distribute it.
Objects are oriented according to the line they sit on. A later update lets you pick an object in object mode so the placed object is linked and can be changed after placement. The crosses and the rail object are helpers you can remove after use, and the point list stays in memory until a new one is made.
Object To Point Rail is best for blender users who need to place mesh objects at exact, evenly spaced positions and orientations along a path built from selected edges, without array or curve modifiers.
Object To Point Rail is completely free to download and use.
Object To Point Rail installs from a downloadable zip (object_rail.zip): open Blender's preferences menu and select install. Once installed it appears under the name Mesh Objects to rail, and you find it in the side panel within the edit menu. From there you build a rail in edit mode by selecting connected edges and pressing Create Point rail, then switch to placing your mesh objects along the resulting points.
Object To Point Rail divides the total length of the rail by the number of points, so the distance between points measured along the rail is the same everywhere. You can switch between setting an amount of points or setting fixed distances between them. Points are marked by crosses, with the first labelled start, and a maximum points shown setting (default 100) limits how many appear so a heavy point count does not slow the computer.
Object To Point Rail can place a linked object when you choose it in object mode, so the objects on the rail can be changed after placement. Objects are oriented according to the line they sit on. The crosses and the rail object are helpers you can remove after use, and the point list stays in memory until a new list is made, while the rail object can regenerate the same point list later or at another location.
Object To Point Rail uses no modifiers, and the rail is not a curve. The rail is a separate object derived from your selected edges and used to calculate the point list; you can remove it afterward, and it can regenerate the same point list again later. Note that results come out strange if the scale and rotation of your objects are not applied first, so apply those transforms before distributing objects along the rail.
Object To Point Rail is listed as free here. For current licensing details, check the developer's page from Tiemen's addons. The addon includes documentation, and a demo video is available. Once installed in Blender it appears in the side panel under the edit menu as Mesh Objects to rail, where you create a rail from selected edges and distribute mesh objects to the resulting points.
