sectionobject parameters

[mrkaplan]

how do i save my parameters to defaults ?

each time i create a sectioonplane i have to change hatch type , scale , and other things .

[pbejse]

Depending on the TYPE of variable

(defun c:test ()
(setq Value
  (cond
    ((getint (strcat "\nChoose a Number <"
          (itoa (setq Value
              (cond ( Value ) ( 1 ))))
          ">: "
        )
      )
    )
    (Value)
  )
)
)

Try it

1. To set the initial value of the variable: ( If (not value) (setq value 123)) where you use your own initial value instead of 123.... 2. A subroutine is often used for the statements to get a new value from the user, like (Defun Get_I (d ps / a ) (setq d (if (and d (= 'INT (type d))) d 0) a (getint (strcat " " ps " < " (itoa d) " > " )) ) (if a a d ) ) ; ...... where d is the default value, and ps is the prompt string, as "\nChoose a Number " in the example by pbejse.....Other similar subroutines at http://auscadd.com/free-lsp-0.html. 3. And there are 2 forms of variable persistence, local and global, so you can set a global variable from inside or outside a defun'ed routine and use it for various jobs. .... 4. And many people use a unique character to identify the global variables, I use the * help me remember.

i could try a simple lisp routine and add it to acaddoc .

the problem is i dont know what variables control sectionobject parameters ( ie hatch pattern , color , scale , hidden lines etc )

also  , i take from your replies  there is no way to do this through the interface , options , cui or else

[pbejse]

Can you give an outline or a brief description of what you want to achieve.

[mrkaplan]

i want sectionobject default settings to be  :

hatch ansi31 ,  scale 3,  color red

tangent lines hidden

[Lee_Mac]

My tutorial here may be of some help with regard to prompting with a default.

To globally remember settings (meaning applies to all drawing files), look into

VL-REGISTRY-READ, VL-REGISTRY-WRITE, VL-REGISTRY-DELETE.

You will have to initialize these values inside your ACADdoc.lsp (or similar).

Create your own section in the registry (meaning do not add to an existing tree),

and make sure to verify the entries exist in the registry before fetching the values.

HKCU\Software\My_AutoCAD_Settings is a start.

Better yet, do as others above suggest - set values inside ACADdoc.lsp.

Avoid the registry to store data whenever possible...

For single instance to remember values (meaning apply to this drawing file only), look into

VLAX-LDATA-GET, VLAX-LDATA-PUT, VLAX-LDATA-DELETE.

These are called Dictionary items. Suggest keeping the entries to a minimum by using LISTs

and accessing the values using NTH...

thanks for your input . my question is still unanswered :

what variables ( if they exist )  control  :

section object intersection fill hatch pattern 

section object intersection fill hatch color

section object background lines display

section object background lines hidden display 

section object forefront lines display

section object forefront lines hidden display

section object tangent lines display

then of course , if those settings can be found in the user interface , id also be interested to know . 

thanks

Hi,

do you mean the standart hatch settings, stored in ACAD system variables HPNAME, HPSCALE and HPCOLOR ?

Take a look to all system variables, maybe you can find your request.

Which ACAD command do you use?

kind regards,

Franz

[mrkaplan]

please read again my previous post  . 

section object settings ar not controlled by hpname hpscale  or hpcolor otherwise it would be a simple matter

[kefer_kb]

Save a simple drawing in DXF format and search for actual sectionobject values. So you can see where it was stored (variable area, tables, dictionaries, ...)

[mrkaplan]

 Tried your suggestion and opened a dxf file with a sectionobject in it using notepad .  there are a couple of interesting headers   ( "sectionobject" or  "section_settings")  but i didnt see anything obvious related to hatch pattern and scale

[kefer_kb]

Be so kind and post a DXF sample file. Maybe other forum visitor or i can help you better.

[mrkaplan]

here is an example file

trying to refresh this topic ...
still no easy solution for autocad to remember setionplane / sectionobject default parameters ?

[mrkaplan]

even " apply changes to all section objects " is broken - nobody seems to notice - starting to wander, am i the only one to use this 😕

[t.leonhardt · Accepted solution]

The easiest way to store sectionsettings is to put the sectionobject in a toolpalette. From there you can drop it into drawing and the settings are restored.

If you familiar with lisp there is another way:

1. grab the sectionobject 

2. get the settings for the 2d-section

(setq a (vlax-ename->vla-object (car (entsel))))
(setq b (vla-GetSectionTypeSettings (vla-get-settings a) acSectionType2dSection))
(vlax-dump-object b)

With (vlax-dump-object b) you can see all the properties you can manipulate.

With (vla-put-IntersectionFillHatchPatternName b "Ansi31") for instance you can set the hatch to "Ansi31".

tool palette works great . thanks
