What's wrong with this HIDDEN linetype?

[lamensterms]

Hey guys,

 

I've been running both AutoCAD 2009 and 2010 for the last year almost - and I had noticed that the linetypes (specifically HIDDEN) are displayed differently in each version. The linetypes are not symmetrical in 2010.

 

Please see attached image and .DWG for examples.

Does anyone know what controls this? Or how i can fix it?

 

Thanks for any help.

Because standard linetypes in AutoCAD always start and end with a dash, and the linetype in your picture ends in a dot, I would suggest that someone has edited your Hidden linetype.

 

Find your acadiso.lin file and see if the Hidden linetype looks this:

 

*HIDDEN,Hidden __ __ __ __ __ __ __ __ __ __ __ __ __ __

A, 6.35, -3.175

 

In passing, I would say that your posted drawing file, supposedly just containing one line, seems to be quite large at nearly 1.5MB

There are 80,484 proxy objects in it with no graphics. PURGE that thang.

The hidden linetype in your drawing has be modified.

 

Hidden line in your drawing

*HIDDEN,__ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __

A,0.423,-0.212

 

 

Hidden line in ACADISO.DWT

*HIDDEN,Hidden __ __ __ __ __ __ __ __ __ __ __ __ __ _

A,6.350,-3.175

 

 

Hidden line in ACAD.DWT

*HIDDEN,Hidden __ __ __ __ __ __ __ __ __ __ __ __ __ _

A,0.2500,-0.1250

Hi guys, thanks for the replies.

 

Regarding the file size - I use an addon package called ProSteel which attaches data to DWGs, causing the file sizes to increase. I haven't been able to purge completely and reduce these file sizes, do you have any suggestions?

 

With the line type... Profcad... How do you read the data of that linetype embedded in the DWG? The .LIN file I use has the correct values for these linetypes, but it seems something is altering it? Is that possible? If the linetype in the DWG is being altered independently of the .LIN file - is there a way I can change it back?

 

Thanks for any help.

Reload the linetype using the linetype command. That will update the linetype to the correct size. If it changes later then ProSteel or something else is changing it.

 

To read the linetype, I used the lisp program located at http://lazydrafter.blogspot.com/2009/04/export-linetypes.html

[eldon]

It appears from the DXF information that this is an S type linetype, (DXF code 72 = 83) so the lisps that extract linetype definitions may not be up the job. Certainly the linetype definitions posted do not produce the linetype in the drawing.

 

ProSteel seems, at the moment, to be the perpetrator.

Thanks again for the input guys.

 

It does indeed look like ProSteel is causing the issue. I tried reloading the HIDDEN linetype and while it did solve the issue of the linetype symmetry (lack of) - it loaded at a different LTSCALE to the one ProSteel had "set up". This solution doesnt really suit me as all our shop drawings are created using a setup which suits the linetype which ProSteel created. I could reload the linetypes (its not only HIDDEN which has issues) and adjust the LTSCALE to suit - but it might be more trouble than its worth - im not sure of the repercussions it might have with other users loading that drawing on their workstations and maybe setting the LTSCALE to the 'old' value.

 

I was hoping that there might be an easy fix or a system variable which would always ensure symmetry with linetypes.

 

Cheers.

sorry to drag-up an old thread,

 

Profcad, how did you determine the line-type definition in the drawing?

 

The hidden linetype in your drawing has be modified.

 

Hidden line in your drawing

*HIDDEN,__ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __

A,0.423,-0.212

 

 

Hidden line in ACADISO.DWT

*HIDDEN,Hidden __ __ __ __ __ __ __ __ __ __ __ __ __ _

A,6.350,-3.175

 

 

Hidden line in ACAD.DWT

*HIDDEN,Hidden __ __ __ __ __ __ __ __ __ __ __ __ __ _

A,0.2500,-0.1250

profcad used the lisp routine in the link he provided.

 

Note that the lisp routine gives the user the option of writing the linetype definitions to a file. The file name will be ltypes.lin and you'll find it in the folder where the DWG file is located.

 

You can see a list of the linetypes that will be written to the file displayed in the AutoCAD Text window. Here is an example:

 

Command:

Write Linetype definitions to a file (Y/N) ? y

 

Writing DASHED definition to ltypes.lin

Writing HIDDEN definition to ltypes.lin

Writing CENTER definition to ltypes.lin

Writing PHANTOM definition to ltypes.lin

Writing PHANTOM2 definition to ltypes.lin

Writing AM_ISO02W050 definition to ltypes.lin

Writing AM_ISO08W050 definition to ltypes.lin

Writing AM_ISO09W050 definition to ltypes.lin

Writing Amconstr definition to ltypes.lin

Writing AM_ISO08W050x2 definition to ltypes.lin

Writing AM_ISO02W050x2 definition to ltypes.lin

Writing Amzigzag definition to ltypes.lin

Writing CENTER2 definition to ltypes.lin

Writing HIDDEN2 definition to ltypes.lin

Writing Amzigzag2 definition to ltypes.lin

Writing ACANSTGB definition to ltypes.lin

Writing ACANSTGL definition to ltypes.lin

lol, thank you, i really should read the whole thread.

 

more haste less speed!
