Hi, I have a problem, I work in a model space and when i look to my work in a Paper Space (Layout) some line lost the scale.How can I fix this??

Hi,
Set variable PSLTSCALE to 0 and use REGENALL to update the linetype scales.
PSLTSCALE = 0 - Linetype dash lengths are based on the drawing units of the space in which the objects were created (Model or Paper).
PSLTSCALE = 1 - Linetype dash lengths are based on paper space drawing units and linetype scales may change in viewports with differents zooms.
Hope That Helps
