Making section frames from a model

Hello everyone,

I am trying to acquire some section frames that i already make a 3d model of a part.

Basically it is a V-shape frame model which has a closed contour inside. 

As you will see in the below image, I applied both features as project lines and split line command to the model from a centerline line sketches and get the projected lines accordingly.

The pink color planes are not parallel to the world axis a slight angled. 

The problem is to save/export these individual lines to the autocad drawing and make a laser cut scheme which I couldnt succeeded.

I tried to make a block from the projected lines-to get it from autocad 2014, btw I am using Solidworks 2019 SP5.

However the line segments are not visible in autocad neither in solidworks save block preview window.

I tried also in 2d drawing but it gives me unnecessary lines like in below screenshot., instead of the basic section line itself. I may give some section depth like as small as 5 mm which is more closer what i want but if there is more clear process without the need of erasing anything else, it would be great.

 

Could you please describe a simple solution to get these lines to the autocad ?

At least could you guide me if there is a similar instruction on how to do that as 

Kind Regards,

Bora
