explode text

[blueshake]

hi,all

I know that expresstool of cad can explode text into lines by using command

"txtexp",my question is :

how they achieve this? thank you for your time.

Look at your ACad install folder. There should be an Express folder under it. In that folder is the txtexp.lsp file. Basically they do a WMFOUT and then a WMFIN.

[blueshake]

thank you for your reply.

I just test the "txtexp" ,but it don't work well.

see the picture. some lines still remain there.

It is working as it is meant to do. You have to do some clearing up yourself.

 

Typically, I explode the polylines, remove the cross lines and then rejoin the letter shape into one polyline around the outside and more internally as needed.

[eldon]

And watch out for the lineweight, TxtExp sets it to 0

[blueshake]

I see now.

[blueshake]

by the way ,is it possible to do the whole process by a lisp.

I mean explode the polyline and remove redundant lines ...

True, but there is more power in other languages

That's because of the WMFOut and -In. That's where these "artefacts" occur. Unfortunately that's something which only ADesk can fix.

 

Edit: Sorry my connection's dead as a doorbell. It took nearly 30min to answer to the 3rd post.
