2d wardrobe symbol

Ahmed_K — Sun, 20 Mar 2022 08:31:29 GMT

Hi,

My gdl skills are almost equal to 0,

In the Archicad library there is a 2d symbol ofca rectangle and a cross inside of it, that can be used for wardreobe 2d representation

Can someone please script an object that can do this, but instead of a rectangle, the shape can be edited,

In3d, the object shows the volume with a given thickness, and that volume can be repeated vertically to a given number with a given distance,

Thanks

Edited to what extent? Still a rectangle?

And I do not get your 3D point or your 3rd drawing...

Here are screenshots to explain better,

Why does a slab not do the job, can you explain how an object would be better? I can't see any major benefit to it being an object, in presentation the doors are likely to be shut or the shelves easily duplicated. For quantities it would just be a single object, where a slab can be easily counted etc.

an object can be parametric, each wardrobe have a number of shelves that can be edited,also, shelves are combined in a single object that can be handled easily without the need of grouping slabs and managing them all together,

for quantitiy takeoff, from an object i can extract :

1 - number of shelves, for that specific wardrobe

2- Area of shelves of that specific wardrobe,

@Ahmed_K This is one for the GDL experts... Extracting the number of shelves is easy, but I'm not aware of an easy way to pull the surface area of a random polygon shape in the standard GDL commands.

maybe using a composite Slab ( alterning wood and air space ) would be better in this way,

or using a simple slab, with 2 properties : shelves count , shelves area ( a formula : shelves count x 1 shelf area )

It's not the modelling that is difficult, it's the maths to calculate the area of a random number of points. I'm sure there are some users round here that would solve that in a few minutes but it's beyond my skill set.

This is true, i have spent many hours trying to write algorithms to calculate the areas.

however there is a way to calculate the total shelf area, But its more or less a hack.

you set the shelf thickness to .001 only in the schedule which will allow you calculate the material area with basically no thickness.

in this case this can be helpful !

the object is used for 2D representation and calculations, no need for the thickness , to represend thikness in section you can just use a thick pen ,

Oh it would still have its thickness everywhere else just not in scheduling so that you could get an accurate reading of the top surface area of each shelf

Hello.

If I understand correctly what you need, this is relatively easy to achieve, including the area calculation (as long as there are only straight segments). You can use the object I posted here to start. You will need to make a few modifications so you can build the array that models the shelves, but it has what you need to get you going.

Hope this helps.

Best regards.

That Area of an Irregular Polygon is pretty neat. Why did we not get taught that in school... Pretty neat and uncomplicated math.
