Loading a linetype

Hi,

How can I load a linetype in the active document using VLisp.
For example, Hidden.

Thanks

 

(setq *acad* (vlax-get-acad-object)
*acad_doc* (vla-get-activedocument *acad*)
*acad_lin* (vla-get-linetypes *acad_doc*)
)

(vla-add *acad_lin* "hidden")

Bill,
From the help file (R2002) this won't work as expected.....

Although you can create a linetype and add it to the Linetypes Collection
object using this method, it will be created with the default properties
only. Because you cannot edit properties of the Linetype object with this
release of ActiveX Automation, use the Load method to load existing
linetypes into your drawing.

Now, if this has changed in the newer releases, then forget I said
anything.... ;-)

 

Use the load method of the linetypes collection.

 

Dang,
Just when I think I know something....

But still the defaults may be just fine.

Bill

 

The "default" is "continuous" which kinda defeats the purpose of a linetype
named "hidden"...... ;-)

So just changing the last line of code you provided to this will work, if it
exists in the file.
(vla-load *acad_lin* "hidden" "acad.lin")

 

Must've changed for 2005.

Command: (vla-load *acad_lin* "hidden" "acad.lin")
; error: Automation Error. Duplicate record name

Command: (vla-load *acad_lin* "hidden")

Works fine and the line is "dashed" by default.

Bill

 

Opps,
I meant to say:

(vla-add *acad_lin* "hidden")

Works fine and the line is "dashed" by default.

Must've changed for 2005.

The first line's error means that the linetype is already loaded in the
drawing, which means the second line (I know you meant add, not load)
doesn't error and is "hidden by default" because it is already
defined........

Make sure to purge the hidden linetype first, then try again ;-)

 

Jeff,

Point taken.

Thanks for the lesson.
