Hi @ToledoX82,

Can you attach the recording directly to the Forums or upload it directly to our Dropbox here and I'll be able to help with this  

Just when I click your Dropbox link, I have to authorise access for our Company Dropbox account to view the recording and while this is likely safe to do so, I'd rather not take that risk

It's an ancient permabug that has been known to Serif for many years: an expanded stroke will be too thin when Size Variance in the stroke properties is not 100%. The closer to 0%, the greater the error in the expansion.

Oh, sorry...

@ToledoX82 you are using a brush. Only the first two brushes in the basic Pen Category will expand the stroke.

I'm not sure why you are bothering to state that. The video shows the expansion is happening, but the result is too skinny because of the bug I wrote about earlier in this thread.

Ok, but if I have a very complex artwork I will need to draw all lines again, just because software don't expand stroke how we expect ?
I don't think the issue is the brush option...
