Lines drawn in Model Space LT2015

[Alasdair1]

I have drawn lines in Model space, checked settings, when I open Paper space some line drawn in Model Space do not show.

Are they on layers set to frozen inside that viewport?
Are you using a viewport?
Do you need to just stretch the viewport to see these other lines?
If you enter the viewport using VPMAX command can you pan or zoom out to see the lines?

So many things to try, start now.

I did not check the layer properties and was drawing on wrong layer. My fault not LT2015.

Glad it was a simple fix: thanks for sharing the solution.
