Change dash line length and spacing

[ctdlc888]

Cannot find lisp to customize dash lines. Say there are dashed lines in a drawing, i want a lisp which asks for the new length of dash and spacing.Thanks

You dont want a lisp you want a line type if ist a simple dash & gap very easy have a look at "acad.lin" its the default linetypes. also you can just change the scale of a line type in the properties box.

 

Just describe what you want. Its easy to make new ones. One of the guys here downloaded some goverment road authority linetypes around 100 different styles.

You can also control the appearance of dashed linetypes using the LTSCALE system variable and the same named feature in Properties of each entity; the appearance on screen is given by the product of the said values. Although, this will not allow you control over dash/spacing ratio. For this you will need dedicated definitions as BIGAL already noted.

If you are looking to affect the entity value trough an AutoLISP routine, then please note that this feature is stored under DXF code 48 in entity's associated list.
