about OFFSET command : erase source/layer settings

[caravaggio]

I would like to ask about the "offset" command, there are options of "erase source" "Layer".

 

 

I wonder if there is any system variables which store those settings. For I would like to make an AutoLisp command which toggles on/off of "erase source" or even to specify offset layer.

 

Thank you

Thank you for the suggestion, but what I am looking for is the system variables (or something else) to control these. For example "trimmode" is to control the "trim" command, so that I can make an Autolisp command to toggle "trimmode" between 1 and 0.

Good question, the only sys Vars that come to mind with the OFFSET command are:

 

OFFSETDIST & OFFSETGAPTYPE

 

But I shall do a bit of digging for you

Express-Tools

Exoffset.lsp …

(setq dist (acet-exOffset-get-dist)

lay (xstrcase (acet-exOffset-get-layermode))

gap (getvar "offsetgaptype") acet-setvar….

Express-Tools

Exoffset.lsp …

(setq dist (acet-exOffset-get-dist)

lay (xstrcase (acet-exOffset-get-layermode))

gap (getvar "offsetgaptype") acet-setvar….

 

 

Thanks for the advise....wonder if I can do this in Lisp (instead of VLisp) for I am not familiar with VLips !!

Hausta refers to the Express Tools ExOffset.lsp which can be found in the Express tools folder - this saves the modes in the drawing using such functions as:

 

(acet-exOffset-get-layermode)

Which are defined in the above .lsp file. These functions in turn use:

 

(acet-setvar)

To store the relevant settings.

 

These are Express Tools functions, not VLISP
