Road Marking

I want a lisp to draw Road Marking with specific length and Gap. Like the line of Paint should be 3 Meter with 6 meter Gap.

Use array path (ARRAYPATH) command

A linetype could easily be defined, and used in a Polyline with width, which will be able to follow curves appropriately [which ARRAYPATH won't]. Is your drawing unit a meter, or a millimeter? There are difficulties you will encounter at the ends of things drawn with noncontinuous linetypes, but there are ways to compensate.

It's the most basic of linetype definitions [one pen-down dash, one pen-up gap]:

*3on6off,- - - - - - -
A,3,-6

which in a Polyline with a width of 1 drawing unit does this:

Why, you don't use HELP? It takes about 5 sec to find how to use a custom linetype. HERE

If the Help article @ВeekeeCZ posted a link to, and the Related Topics there, don't explain it well enough for you, come back with questions, and we can probably answer them.

I think we've been through this before.

Since I doubt that there's any paint truck that can read an AutoCAD drawing and is tied to a geodetic grid to know the coordinates of the ends of any paint stripe, your job is to simply represent the impression of dashed lines. Use a linetype and ltscale that suits the impression you want to create, include a detail if necessary of the stripe length and gap, and know that the traffic marking subcontractor will make it come out good. Also, take your paycheck for a job done well and efficiently and go home with some presents for your wife and kids, or whomever is dear to you.

Agree with John the contractor will fix any subtle errors.

Some line types, for roads and general.

Did you try the linetypes you save as a .lin file like custom.lin then just do Linetype Load and pick the linetype file you can load 1 or all, save to your template dwg so there always their.

A freebie for you lots of linetypes.
