Nice to see you again, Jber.   The space increase in your image seems improbable, especially at the beginning. Depending on the way you wish/need the increase, you can, Smart Guides and the Line Segment Tool being your friends: 0) Create a midline for the set with the right length, angle span, and position, and a Stroke Weight of 1pt; 1) Create a horizontal set of vertical lines with the desired number, Stroke Weight and length, and increasing distance, in the most convenient way, which may be the Effect>Distort&Transform>Transform Effect with a suitable low Horizontal Scale and a suitable Horizontal Move and the deired number of tick marks that is expanded afterwards; 2) Object>Expand Appearance; 3) Turn 2) into a new Art Brush in the Brush palette; 4) Select the midline from 0) and apply the new Art Brush.   You can go back and forth, trying out different values and go back and forth between the steps; keeping backups of different versions of the artwork and Undo are also your friends.   If you wish to have the area shown as a frame, you need to add a horizontal line at top and bottom to the final version of the expanded horizontal set in 2), as follows:   1+) Ungroup the set twice, and Group the set again, then Join the first and last lines (you can deselect and then Direct Select the top Anchor Points and Ctrl/Cmd+J and do the same for the bottom ones, to turn those lines into a rectangle; it is safest to set the Cap to Butt (for the whole Group).   Below is shown a sample made as follows, just to give an impression In 0) the midline is shown in red (at the very bottom), made as 45 degrees of a circle (originally with W=H=720pt, and rotated to start at 30 degrees from vertical corresponding to 40, going anticlockwise). In 1) everything starts with a 30pt vertical line (Stroke Weight 1pt, Butt Cap), then Effect>Distort&Transform>Transform with a Horizontal Scale of 101% and a Horizontal Move of 5 pt (to start with, which will then increase) and 60 Copies (random number); the rate of increase increases with the Scale; you can try out different combinations till you hopefully get it right. You can already get a basic impression by this.   In 2)/3), The set is shown without and with the horizontal lines (possibly) added in 1+.   In 4) the final result is shown without and with the horizontal lines Click to get closer, Click again to get closer still ...

Vladislav,   I am unsure whether you use it already, but otherwise you can ease the pain with the Line Segment Tool by ClickDragging from the Handle into the Anchor Point, snapping to both; and you can easily move the line to the other side of the Anchor Point (ClickDrag by the Handle end to snap); and you can easily extend the length of it.   For angles, you can rotate the (Line Segment) line round the Anchor Point by a specific angle (select the line and Alt/OptionClick the the Anchor Point with the Rotate Tool) if applicable, otherwise your circle way is fine as it is.   Smart Guides are your friends.     ...

defaultt,   You need two of each, one as the default appearance and one to enter the Knockout Group, and the one that serves as the mass object needs to be at the top (obvioulsy, since the others are behind it), in this case the black one; and all paths have a stroke and no fill.   You can use the following steps, making sure the black one is at the top:   1) For the black path, select and Ctrl/Cmd+C+F (hold Ctrl/Cmd and press C then F) to create a copy in front, then lock the copy in the Layers palette (with the Layer expanded); this is the selected path, so easy to find; 2) Select the unlocked original from 1), then switch from stroke to fill, then set the Opacity to 0 in the Transparency palette; 3) For the other paths (red and blue and whichever additional paths you wish), select and Ctrl/Cmd+C+B (hold Ctrl/Cmd and press C then B) to create a copy in back, then lock the copy in the Layers palette (with the Layer expanded); this is the selected path, so easy to find; 3) For each of the other paths, ClickDrag over it with the Direct Selection Tool and apply Dashed Line as desired (you can hide the locked duplicate to see); 4) Select all the non selected paths and Ctrl/Cmd to form the Group, then tick Knockout Group in the Transparency palette enough times until you have a full tick mark; 5) Unlock all locked paths in the Layers palette; now you are ready to move;   To move any of the path sets round freely:   6) With the Direct Selection Tool, Alt/OptionClickDrag (hold Alt/Option and ClickDrag) over the path set(s) you wish to move to select it, making sure to avoid selecting other path sets that need to stay in place, then ClickDrag the path set(s) by any segment/Anchor Point to move to the desired position.   In 6), you can select multiple path sets (such as the red and blue one, avoiding the black one), so they are moved in the same way.   If you are unable to select all path sets you wish to move in the same way at the same time in 6), you can use ShiftAlt/OptionClickDrag (hold both Shift and Alt/Option and ClickDrag) to select the path sets in multiple steps.   The Alt/Option lets you select whole paths.   The Shift lets you select more path sets together; you can skip it for the first set, but it is simpler and safer to use it throughout.   ...

Jules,   I agree with Bobby in the use of a combination of outer shape(s) and blends.   Another way to create the perspective tyre track impression while keeping the same proportion of widths of the (track/tread) lines and the gaps in between could be to start out with uniform blends of many thin lines between the outer shapes, then expand each blend, then delete lines within the desired width of the (track/tread) lines and join the ends of the remaining outer lines with narrower gaps in between.   ...

Jean Louis,   It is very simple if you actually do exactly that "un texte curviligne dans cercle".   Starting with a circle corresponding to the Baseline (no Baseline Shift), you can do it by using a negative Baseline Shift equalling the font size applied to a circle that is twice the font size larger.   In that case you can just create the first instance and then simply use Effect>Distort & Transform>Transform with a Rotation of 60 (or you can use 360/6 which gives full accuracy if you choose another number such as 7) and 5 Copies.   Below it is shown with 24pt font size in a 648pt circle (copy added in red) corresponding to an original circle of 600, 600 + 2x24 = 648pt, with Align to Center applied in the Paragraph palette.   Starting with a positive Baseline Shift as in your image, you can subtract that from the font size and apply to a circle that is twice that amount larger (such as 600 + 2x18 = 636pt from a Baseline Shift of 6pt).   Click to get closer ...
