Parapets in plan

Is this a wishlist item?

I have a parapet wall on a roof storey, directly over a same width and constructed wall underneath, on a lower storey. When I draw a section, both parapet and wall under join perfectly and are hatched alike. Just what I want. But when I go to the roof plan, my parapet walls are hatched in plan -which I don't want. Drafting conventions are that items which are cut are hatched, items which are viewed from the top, are not hatched. Full height walls are traditionally shown hatched, but low walls are shown plain. There are work arounds - like putting a blank fill over the wall - but is there an easy, automatic way?

It is a wishlist item and no, there is no easy automatic way ...

presumably there's some sort of coping to weatherproof the top of the wall

so, draw the wall on the storey below to the u/s of the coping, then draw the coping with the slab tool (or mesh if it has a raking top)

Exactly what I do ... with the added benefit of being able to show one storey up or down. You can also do the coping beam using the beam tool, that solves the problem somewhat.

You could probably do this using the display option to turn off fills inside walls on the roof plan.

because we often use a slightly different wall construction/composite for the parapet walls, we find that using a separate layer for copings works well:

the parapet walls are drawn on the usual external walls layer to the correct height, hatching and all. then we use a low thick wall for the coping with a solid white fill over the top of the parapets.

this means that GA plans, containing all the building information, display correctly on output, but toggling the coping layer and GA notes layer off, and turning on parapet notes, we have a drawing set for the parapet walls.

Thank you for your replies. The issue also applies to internal low walls without copings - such as low walls around stairs. It is more concerned with principles of presentation in draftmanship.

I will put a thin coping over the parapet, and associate text notes with it.

While we're contemplating the long standing parapet wish list item, it would be great to have this coping workaround incorporated directly into the wall tool. You could specify if the wall terminated in the current plan view and go on to give dimensions, type, materials for the coping, which would show properly in section and elevation and clean up nicely in plan without displaying a fill. Maybe there's an option to show the wall below in dashed lines?

Mind you, not another wall accessory add-on type thing, please: A basic enhancement of the wall tool.

how about as an enhancement to the wall end tool?
