Adding line segments at a fixed interval.

[solenoid_jam]

To accurately work with geometry, you need to create a function for adding segments of a specified length. This is similar to how the Fast Draw plugin splits a line, but with the difference that the split length must be specified with exact numeric values. For example, 1 meter (feet), 12.4 meters (feet), 150 meters (feet). The exact segment length is specified as a number in the value input field. When this mode is enabled, all subsequent segments will have a length multiple of the specified length until it is disabled. For example, 1m, 2m, 3m, 15m, 141m, or if the segment is a multiple of 9.5m, then 19m, 28.5m, 133m, 636.5m, etc.
This feature should be a great addition to the snap-line drawing feature, as cities have many similarly sized elements, from the dimensions of typical buildings to the regular grid of streets or park paths.

I probably don't understand what you need. Can you give a real world example were you first draw a line and then decide to add a nodes with exactly the same distance? I only do this with straight lines and only to distribute n nodes equally (Shift+B)

[GerdP]

Or do you want to set the offset first and then, while drawing a line, the cursor will always snap to next multiple of the given length?

Replying to GerdP:
I want the line segment length to be a multiple of a specified value. When we move the cursor, the next point can be added within a specified radius at a certain step. This is similar to snapping angles (AA mode), but it affects lengths rather than angles. Both modes should work separately and together.

Imagine you need to draw a building that is 75 meters long and 15 meters wide. No more, no less. Then you could set the divisions to 1 meter, or 5 meters, or 15 meters to achieve the appropriate size. Or you could create intersections for 17 paths in a park, every 27.6 meters (or the distance you specified).
Please see the second attachment.

I think I understand what you want. I just never know the length or width of an object unless I draw the line and check the value in the status line. I assume you have a source that gives the distances and you want to use this knowledge as precise as possible?

[GerdP]

OK, I know one use case for me: I sometimes map pipeline markers and those give one or two distances to locate a place where I want to draw a node of the pipeline. These distances are given in multiples of 10cm, so I can imagine that it could help to draw the help line(s) that I need to find the exact place relative to the marker node.

Replying to GerdP:

Yes, this will allow us to use precise values ​​if they are known. It will also help with the placement of typical buildings or in marking out blocks if we know the distance between adjacent streets is the same.
