polylinear perpendicular lines, prefixed step

[micheledag]

Good morning, everyone.
I wanted to ask if there is a lisp that allows, selected a polylinea 2d or 3d, to insert the centered perpendiculars (lines) (maybe also these of desired length) on it to prefixed pitch.
practically is the problem of getting section lines on a polylinea that represents a road axis.
then the sections will be extracted with the formidable autosez2!
If this debate has already been addressed, please address me to the right one and to cancel this intervention.
thanks for the courtesy and attention.

Michele, it's a problem easily solved.

creates a block containing a line, with insertion point in the middle of the line. Let's say you call it "sez."dividing (in case of prefixed number) or measure (in case of fixed step) your polylinea.

when measuring or dividing, you will be asked if you enter a block (to which you will respond yes and at the request of the block name you will respond "sez")
You will be asked if you align the block in the split/measure phase and you will respond yes. and the game is done.

default (or number) lines, perpendicular to the pline at the sectioning point.
I've never tried if it works on those 3d, but on the 2d it's a certain procedure. without any lisp.

Thank you so much!! !

also works in 3d: tried to believe! :finger:

fantastic!, autocad e' una miniera

the suggestion provided by giuseppe mauro is very valid.
You can also use the "series" command along trajectory. with the subcommand "elements" you type the distance between the sections. you can also choose whether to align or not sections with the trajectory.
works with polyline and spline with both flat and inclined trajectory.
