MEP symbole

[Camu]

Hello, Is there a way to have the graphic symbol in the MEP plan in a straight line. Indeed on the plan I have pipes under the ground floor slab in a solid line and heating ducts on the ceiling of the slab on the ground floor which should be displayed in a straight line, in order to differentiate their situation in the plan. (pipe -50cm from the ground floor and heating +350cm from the ground floor). this for archicad 28

Operating system used: Windows

Here are some screenshots. We can see that the symbol in the plan is poorly represented. The lower deviation should be in view and not in a cut segment. In addition, it is redisplayed in the upper floors. Which is not desired.
