Problem with cladding

[16220316]

Hi everybody,

I have a problem with claddings. Im using latest Robot SA 2014 professional.

The problem is, whenever I try to define a CLADDING it shows up in Object Inspector as a regular Geometrical Obejct, a Contour. This makes impossible to define a surface load (or any other kind), each time I try to perform a Calculation following error shows up: Loads applied to faces withouth claddings will not be included in calculations. Im working on a 3D Frame but my problem also occurs in Building Design (didn't try anywhere else). I used to know how to work with this tool, apparently something is different in latest version.

Attach a sample file please.

Here is a sample. I'm not sure if this is what you asked for though. Thanks for any kind of advice.

It does not seem like a satisfying solution. That way cladding has no purpose at all. But if I'm to accept it I guess I need two questions to be answered.

1. How can I make curtain wall exclude from FEM? I don't need/want waste resources on meshing. 

2. How how can I make it to distribute load one-way ?

Have you actually tried to switch off default definition of surface objects as ACIS, restart Robot and then create a new model with a cladding ?

"as you defined them as ACIS object which is not recommended for panels I would suggest to set the preferences as on the same picture, delete these objects, save the file under a new name, restart Robot, open the file and define them again as claddings."

1. How can I make curtain wall exclude from FEM? I don't need/want waste resources on meshing. 

Have you checked if a curtain wall is actually meshed?

"The only difference between a cladding and a curtain wall is that you can apply self weight for the later based on the assigned thickness."

2. How how can I make it to distribute load one-way ? 

You should assign such parameter to a defined cladding (or select it in the dialog above for a curtain wall).

If the above does not solve your situation send me such the models created in this way.

Thank you for your contionus patience. When it comes to meshing it did in fact mesh despite the option "no fine elements" was marked, that's why I felt the need to ask. As for my primal problem, it seems that everything was fixed by unmarking "define by default in a Solid Modeler format". What's more, I investigated once again "curtain wall" issues and it also works like a charm. I dont know any details about Solid Modeler but apparently it is something I should avoid in the future! Thank you again.

Hi, i'm confused. Yesterday my claddings are not attach to the floor plan, it's like in the middle between floor to floor. I try to deleted the claddings since the area loads were attached to the claddings and the beam didn't carried any area loads and i delete all the area loads too, and start draw a new claddings that attach in the floor plans, and assign  a new area loads to my new claddings that attach to the floor plans. But when i start calculation there are instability type 1 and 2 and the warning still the same which are:

1. Linear loads has not been applied to a panel

2. Loads applied to faces whithout claddings will not be included in calculations

3. And instability type 1 and 2

What should i do?? Please help 😞

Here are the screenshot and the robot model file before i draw new claddings
