How can I express a thick line as a thin line in a cross section?

[LeeJaeYoung]

Now this is a cross section.
I want to make the left equal to the right.

Then, the insulation material and the external finishing line are not thin lines.
It is expressed as a slab section line.

Line thickness is controlled by the pen settings.

Make the pen thickness for the pen you have used for those lines a thinner weight.

My guess is that it's not a pen assignment issue.

I use a different pen set for sections views that has the same pen set as a thinner line. In my case the section lines are thicker than the same pen in floor plan view.

Pen number 12 surrounds the concrete in your composites.

Have a look in the pen set to see what the thickness is of pen 12.

Compare that to pen 16 which is not showing as thick.

It looks like you are then turning on/off the 'show true line weight' option which will either show you all hairline thickness if off and true line weight if on.

The inner line surrounding the outer material was the line for the concrete.
So, it is enough to make one more with a thin line for the inner line of the outer material.
thank you.

Going by your images, you are using pen 12 for the thick lines.

These are the only ones showing up as thick in section.

That makes me think they are thick in the current pen set you are using for the section.

The other lines for the other skeins use pen 16, and that seems fine so it must be a quite thin pen.

Can you show me the pen settings for each pen.

Pay no attention to my pen colours, they will be different to yours.

Or you can change the pens in your composites from 12 to 16 and see if that makes a difference.

If it doesn't then I am off track with my explanation.

thank you so much ^^

While I was asking a question, I came to understand with your advice, and I already solved it, but I guess you didn't see it ^^
Thank you again.
