solved break a line at a nearest point works only with manual command

[vanowm]

Hello.

I'm experiencing a strange situation with break command. I want to cut a line at a specific place using "nearest" snap.

I use the following commands:

Quote

 

break

<select a line>

f

<pick a point on the line using "nearest" snap>

@

 

This works perfectly, a line splits into two at the selected point.

 

However, when I attempt use of

(command "break" pause "f" pause "@")

it removes chunk of the line...what am I doing wrong?

 

P.S.

This worked fine in AutoCAD 2002

 

 

[EDIT]

By adding nea before submitting second point seems to fix the issue.

But I still would like to know why there are different results when commands entered manually vs using (command) function

 

Command: break
Select object:
Specify second break point or [First point]: f
Specify first break point: _nea to
Specify second break point: @

 

Command: (command "break" pause "f" pause "nea" "@")
break Select object:
Specify second break point or [First point]: f
Specify first break point: _nea to
Specify second break point: nea to @

This is why i try to stay away from using (command  it doesn't always  behave like it does when your typing in commands. I don't remember the command but I found out that using (vla-SendCommand worked when (command was giving me issues.

 

(vla-sendcommand (vla-get-ActiveDocument (vlax-get-acad-object)) "break" pause "f" pause "@")

Chalk it up to you have a setting that is set different or AutoDesk programmed the break command updated/changed since 2002.

(command "break" pause "f" pause "@") worked for me in 2019 BricsCAD.

(command "break" pause "f" pause "@") works on AutoCAD 2022 for me as well.

I've already found a few other commands that are different when used (command). I.e. fillet, note the options:

Command: fillet
Current settings: Mode = TRIM, Radius = 0.0000
Select first object or [Undo/Polyline/Radius/Trim/Multiple]:

 

Command: (command "fillet")
nil
Select first object or [uNdo/Polyline/Radius/Trim/mUltiple]:

For fillet if I remember correctly fillet supports various methods in lisp.

 

Just looked through code I have and there are 3 different ways.

pt1 pt2,

ent pt,

ent ent.

I think it depends on what your filleting like a pline and a line.

Yes, but why in the world would they change Undo to uNdo and Multiple to mUltiple

It wasn't the case in AC2002
