Did you increase the Fuzz factor value? The MTEXT objects may be further away from the leader ends than the default 0.1, which if you are working in mm is a pretty small value.

Geometry and dimensions need to be placed precisely within your drawings to ensure accuracy when your digital design is taken into the real world to be manufactured or built. There are several precision features available when creating and modifying objects, including: Coordinate entry: Specify a location by its Cartesian or polar coordinates, either absolute or relative. Polar tracking: Snap to the closest preset angle and specify a distance along that angle. Locking angles: Lock to a single specified angle and specify a distance along that angle. Direct distance entry: Locate the next point at a specified distance in the direction of your cursor. Object snaps: Snap to precise locations on existing objects, such as an endpoint of a polyline, the midpoint of a line, or the center point of a circle. Grid snaps: Snap to increments on a rectangular grid. For our AutoCAD Foundations blog series today, we’re taking an overview look at one of the most popular precision features: object snaps. For the full tutorial on using object snaps and even more of these features listed above, you can check out the AutoCAD Foundations article. In the meantime, let’s take a look at what object snaps are and can do for you. Get Started With Object Snaps Objects that make up your designs rarely fall on precise coordinates. By far, the most important way to specify precise locations on objects is to use object snaps. In the following illustration, several different kinds of object snaps are represented by markers. Object snaps become available during a command whenever you are prompted to specify a point. For example, as you draw a new line and move the cursor near the endpoint of an existing line, the cursor will automatically snap to it and is identified with an AutoSnap marker and tooltip. AutoSnap Marks of Common Object Snaps The following table illustrates commonly used object snaps.

Ill look into them, although I would appreciate if someone would at least fix this bug i mentioned.

The lisp doesn't work for me 2393 Leaders Selected : 0 MTEXT objects associated.

Thanks for the help DATVO and Saxlle.

@mhy3sx I made the same command (I hope the ZWCAD have the same functions as AutoCAD), but with the less line code and a different approach. It works the same as @DATVO modified your code, the result is the same. ; ******************************************************** ; Functions : stair2D ; Description : Drawing 2D stairs between two LINE ; Author : SAXLLE ; Date : August 07, 2025 ; ******************************************************** (prompt "\nTo run a LISP type: stair2D") (princ) (defun c:stair2D ( / old_osmode old_aunits old_layer flag ent pt1 pt2 pt3 dist num_steps equal_offset half_dist ang new_ang circle_radius off npt midptdel midptbase val midpt1 midpt2 midpt3 answ) (setq old_osmode (getvar 'osmode) old_aunits (getvar 'aunits) old_layer (getvar 'clayer) ) (setvar 'aunits 0) (setq flag T) (while (not (equal flag nil)) (setvar 'osmode 1) (setq ent (car (entsel "\nSelecte the BASE line:\n"))) (while (or (equal ent nil) (not (equal (cdr (assoc 0 (entget ent))) "LINE"))) (prompt "Try again...")

Hello World. I've used all the swear words I know and this block still won't behave! When I use the Move grip and pull this block all the way up, it should extend by 5-7/8" ... instead it extends by 5-3/4" and also moves 1/8" from the Basepoint. Any clue what's going on here? Thanks in advance y'all!!! jack.dwg

Hi DATVO. Yes , I update my code to work only for the left side every time.How you do it? Can you post the code? Thanks

@HypnoS,, Glad to know. My version do not INSERT , just copy as you asked at the OP. Seem to be you need to make RISERS.

The OP disappeared without answering any questions.

A word of warning, bedit/attsync might change the block handles, but not always. I'm not sure what triggers it.

Thank you very much BIGAL!! I really appreciate it! I didn't run the code yet, but I analysed it - are there 2 redundant procedures? ColumnRow and Alfa2Number that is only used in ColumnRow?

Does this match your expectations?

I will add the set property later but this is front end as an example, just copy all the code and paste to command line .

Thanks @devitg it works great!

Maybe this. Does numbers and alphas, as well as a square or circle. Pt num bubble.lsp

You don't use a look up table, as you mentioned just answer the question for length, then add the various blocks selecting the visibility state, you insert the block then call the dcl so can pick which visibility you want then its updated much easier that picking the Blue square and then selecting visibility. Post a new sample dwg with the separate blocks maybe a couple of different structures. Then can look at automating it.

... And the system variable would still remains you set it firstly. Right?

Hi I am writting a lisp to draw 2d stair. The idea is to select the fist step --> move it to layer STAIR then pick two points for the length of the stair and give the number of the steps. Then the code draw the stair with direction arrow in the middle. The code work perfect if i select the two points only from the one side of the stair. Is not all the time the left or the right side depends of the rotation. Can any one help me to update the code to work for bouth sides and don't misalign the steps. Here is the code . By the way i use ZWCAD.

First, the code sets CMDECHO to 0 to prevent program from displaying commands like MLEADER or its interactions in the command line. This helps keep cleaner while the program runs. At the end of the program, the code resets CMDECHO to 1, which is AutoCAD's default setting. I copied my old file into this one, so I probably forgot to remove that line. But in this code, it's not necessary. The command will cancel.

Good start. A few points if you like: - what would happen if a user pressed ESC while Mleader command is active? - What's the need of function vl-load-com in your routine? - You assumed that the system variable CMDECHO was set to 1 but it could be the contrary.
