Robot mesh

[Anonymous]

Hi,

I am aiming to design a new hopper and have a had a number of issues with Robot. I think the problems come as the points of the contours are not aligned on the same plane due to the slightly un-symmetric cranked beams. 

I have gone through the posts that Autodesk robot has on youtube and your website and spent a lot of time trying to sort out this issue unsuccessfully. Does Robot count with a tool to address this?  I am aiming to attach my model for your reference but it is not allowing me to giving the following error for many attempts:  The attachment's twin hopper v2.rtd content type (application/octet-stream) does not match its file extension and has been removed") to submit the file.

Could you advise how to attach the robot file as well?

Thank you,

Miguel

File attached.

Thank you.

Hi @Anonymous 

Out of curiosity, should these be so inaccurate?

(And many more - make big zoom in corners)

Thanks Rafal.

Every time I try to snap the panels to these type of nodes, it spoils it from elsewhere within the panel. 

Is there any tool to converge / address these issues between panels and bars?

Thank you.

Hi,

I got all the lines intersecting within the model, but now I am getting a message of separate structure which I am not able to address.

Could you please advice what is going wrong as the deformations and stresses seem very excessive?

Thank you,

Miguel

There are still many panels which do not line up.

Best approach would be to use Detailed structure correction which allows to put panels and nodes into one plane. In some cases it's just easier to start again with more accurate model or make a frame say in CAD and import into Robot.

Detailed structure correction  can be found under EDIT-->Detailed correct...

To check for separate structure, go into node selection dialog box and use drop down arrow, here you will see node sets which are separate. In your case all mesh nodes are not in the plane of the panel.

Hi Rokas,

Thanks for your prompt response. If you have a look at the background file, we are already using a frame imported from Inventor in which we have made sure the lines were both in-plane and intersecting. So I am not too sure why Robot is behaving like this, as I have snapped both steel members and panels to these nodes. I do not think I can do anything else in this front.

With regards to detailed correction I am trying this and still getting error messages. I figure that when you sort one in plane geometry then you make another misaligned.

I feel a bit stuck here not sure where to go.

Thank you,

Miguel

Attached model which works, but I may have removed loads etc. Didn't have much time but wasn't too complicated. There were bars not connected so it all comes down to accuracy when creating geometry.
