hatch variable

[davian]

hello all,
how can I change a variable value to have the three different type of boundary Island filling (Normal, Ignore or External)?
thank you

 

[davian]

perhaps I'm not clear!
I am trying to do something like that
(command "_boundary" "a" "g" "n" ss1 "" "I" "_n" "v" "" point1) and have recognized only external boundary of selection set ss1

thank you
Davian

You just have to step through the -boundary command at the command prompt and answer "Y" for the Island detection option. Just follow what the prompt would do if you were doing it as a manual command. Then contruct your command line to do the same.

Davian,

The subject line says "Hatch variable" but the code snip from your reply to Bill uses the boundary command. On my AutoCAD, those command arguments posted don't work for boundary or hatch commands.

If you mean hatch, another way to toggle normal, ignore, or outer hatching behavior is by appending a special string value to the current hpname variable before hatching. The string value is a comma "," followed by either letter "n" for normal, "i" for ignore, or letter "o" for outer. Letters can be either upper or lower case.

For example:

(setvar "hpname" "ansi31,n") forces normal behavior
(setvar "hpname" "ansi31,o") forces outer
(setvar "hpname" "ansi31,i") forces ignore

Hope that helps,
Steve Doman

thank you Steve,
I've confused two different commands in one like in my mind seems to be. Now, my question is: Why cannot I have only the outer polylines or regions from a selection set, using -boundary, and I have to erase the internal polylines? I don't expect e response, second thank you!

Davian,

Are you using a non-english version of AutoCAD? That would explain why your code snip does not work on my AutoCAD.

If I understand your question, you may need to study the use of AutoCAD variables Pickstyle and Hpbound.

Pickstyle controls associative hatch selection, i.e. whether the boundary is included when selecting a hatch object.

Hpbound controls whether the hatch boundary is a polyline or region.

Hope that helps. ?
