Replacing an existing linetype

[asloat]

Hopefully a simple question.

We have an existing drawing with a linetype that uses a shape file as part of its definition. For whatever reason the shape file is not loading and the line appears as just dots.

If I open a brand new drawing and use design center to drag that linetype out of a drawing it works in, it works correctly. If I dot he same into the drawing it is appearing as dots in, it doesn't change anything.

I believe this is due to the fact that is is already defined in the drawing and brining it in from design center won't modify an existing linetype. Unfortunately despite purging the drawing and making sure no layer is using the linetype and all lines are set to by layer for linetype, I can;t get rid of it from the drawing to redefine it as a fresh entity.

In this case we are simply going to create a new blank drawing, define the line correctly and bring in the data from the old drawing, but in the future this might not work as well so I want to get soem feedback on how to do this differently.

Thank you

The only thing I can think of is that the linetype is used in a block or style. That would prevent it from being purged. What you're doing is exactly what I would have recommended. Let us know how it goes.

I used selected everything in the drawing and filtered to blocks and exploded all of them to test that as well. I also detached all xrefs. Selected everything, no blocks left and changed all objects to linetype "by layer". No loayer is set to use that linetype, purged again, still won't purge it.

Still might be in a Style. Have you tried to list blocks to see if there are any still defined?

Command: -BLOCK
Enter block name or [?]: ?
Enter block(s) to list <*>:

Is it just one line you have set to that style. If so. Check if it's got at delta Z. That can mess up the display of the linetype.

If you load a linetype from file, is there a way to redefine an existing one in the drawing?
(Similar to inserting a block and redefining the block definition in the drawing.)

Does the folder path containing the shape files it's looking for exist in options?

Options>Files Tab>Support FIle search Path> add the folder containing shapes here if available

If you'd like to try to find and remove the missing shape so the line can be purged, I've had success with this Fndshape.lsp.

Have you tried reloading it with the Linetype command?

I think that dragging from Design Center should behave the same way. But I can't say for sure.

With blocks in the Design Center, you can insert, insert and redefine, or Redefine only. Unfortunately linetypes don't have the same options; all I see is "Add Linetype" or copy. It's not clear to me that clicking "Add Linetype" will redefine it in the current drawing.
