Sophia® doesn't recognize my tube. What can I do?

If Sophia® does not recognize your round or rectangular tube, this is usually due to one of the following causes: 
  1. The tube is recognized as a plate
  2. The tube has varying wall thicknesses
  3. The tube does not have a closed contour at five measurement points
The first cause is due to a validation sequence in Sophia®. Did Sophia® recognize a tube as a plate? If so, you can easily correct this by changing the part type.

We explain the second cause in our blog post on the top 5 design errors for tubes (see the first point). Is this the case with your tube? If so, adjust the drawing and upload it again.

The third cause stems from how Sophia® analyzes tubes. The online software checks them  at five points (start, quarter, center, three-quarters, and end). If the part is “open” at all these points, Sophia® does not recognize it as a tube. At least one of these points must be closed. 

Does the above apply to your tube? If so, consider adding a small bridge as a connection in the middle, for example, or adding a “ring” to one of the ends. You can find examples here. Note: If necessary, you will need to grind down both connections yourself.
