Marquee tool in sections/elevations

[kielbasa]

Hi,

I built a small barrack made of wooden planks, with each plank represented as a different column. The structure has walls, a roof, and some simple geometry. I need to make the whole thing higher and know how to increase the height step by step by adjusting the parameters of the selected objects like walls, columns and elevating the roof with rafters. However, I’m wondering if there’s a way to use a marquee tool to select the upper portion of the building and stretch it upwards, similar to how it works in the floor plan. I could make the entire structure taller with a single click this way.

I can't seem to figure it out. Is this generally possible?

If not in Archicad 18, perhaps in a later version?

thanks!

Operating system used: Windows 18

Usually the easiest way would be to link the element with it's top to the next story.

The trick is to always have one more story than you actually need (I call that one roof top view).

It's a "virtual" story which only reason of existence is to have an upper bound to link the truly highest element to.

Then you can just go into your story settings and modify the height of the now second highest story – all linked elements will make the change!

Thanks for that solution, however, that doesn't actually answer my question about the marquee tool 😉

The marquee won't stretch in elevation, but you can select multiple elements and stretch their height all at once (for the same element type) in elevation or 3D.

You cannot use the marquee to stretch entities in elevations and secitons.

It's strange that it hasn't been possible across so many different Archicad versions... It should work the same as in the floor plan.
I'm using AC 18, and tested 28, so it's 10 versions later, and there are many unnecessary updates while those that could be helpful ones are still missing.

In plan you are simply stretching the lengths and angles of the elements.

In elevation it is not that simple.

Take walls for example.

Some walls will be perpendicular to the view some will be parallel, and some could be at any angle in relation to the view.

It might work if the marquee only allowed you to stretch vertically.

Otherwise it will not work as it would have to incline the wall, but due to the different direction of the walls in relation to the elevation, as they would all need to be different.

Those parallel won't incline, those perpendicular or at other angles will incline (but you probably won't want them to).

And then you have other elements, columns, slabs, roofs, etc.

Much easier to select element and use the appropriate pet palette option to stretch (or incline).

I just checked, 2D elements in elevations stretch with the marquee.

Whether we look from above - plan, or from the side-elevation, it's the same kind of  'flat view' where no perspective is present. I don't really see the problem with why in the floor plan it's easier to achieve. In both cases, it should work on the x and y axis, like it does on the floor plan. It's just the problem of proper implementation.

[Barry Kelly]

The floor plan is a 2D representation of the 3D model.

Elevations are a 3D view from a particular point, not 2D.

That aside, in plan you are simply adjusting the lengths (reference line) or perimeter geometry of the elements.

In elevation you could be stretching vertically (which is probably what you want), but you could potentially stretch sideways, which may not be possible or wanted for some elements.

Which is why I mentioned it may work if limited only to a vertical stretch.

Plus, in elevation you will have many elements hiding behind other elements.

Some walls will be parallel to the elevation, some will be edge on, some may be at an angle.

Some may be inclined which means even stretching vertically will alter the angle of inclination.

Then you have slabs, does the marquee stretch the thickness of the slab or just move the slab?

Can you stretch the length of the slab?

But the slab can be any shape so how do you mow what points you are stretching (you can't choose the nodes/edges like you can in plan because they will all be hidden behind one another).

I don't even want to think about how roofs will stretch.

Sure there will be simple scenarios in elevation that a marquee stretch should work, but I think it can get way too complicated to do properly.

I understand Your point but maybe the problem and the solution lies at the source then - why the elevation is a 3d side view not a 2d plan from the side....?
