You can create a markups curve with two endpoints and choose “Shortest distance on surface” curve type:

The curve will go through the mesh points, so if the mesh resolution is low then the curve may not be smooth/straight. If you find that the curve is not good enough quality then you can subdivide the mesh to have more candidate points for the curve to go through.

Dear Lassoan, in my vision (4.13.0), there is no vessel in Model Node, should i download some module?

You can choose any model node. If you have the aorta as a segmentation node then you can export it to a model node by right-clicking on it in Data module.
