Dear Mr. Far,

Thank you for the tutorial on youtube, I have watched our valuable video guidelines here: https://www.youtube.com/watch?v=0Qmm9sKQaFc

However, I just have a few questions, could you help me clarify them?

What is your purpose of "Slice" step here? Is it for purpose of sketching flowpath such as hub, shroud, etc later? What if I have already a hub trimmed with a blade when I import to DM? Like what in the picture I attached. Do I need to "slice" again?

How did you sketch lines of flowpath such as inlet, outlet, hub, shroud? I mean to the exact locations meanwhile there seems no obvious constraint except for visual view?

Could you send me your tutorials that you mentioned in other topics via my email? I have messaged you my email address.

Thank you very much.

I always got the small error (That means it still appears a "v" sign, but not a green color, instead a yellow color) "All FlowPath contours must be defined on the +y side (y > 0) of the sketch x-axis"

This error leads to the consequence that the number of layer is 0 instead of 2 like what appears on your video. Then the error when I export to Turbogrid.

I have tried to change all y value coordinates by increasing 1mm. If I apply the new flowpath pane on y = 1mm, I got the error of not correct meridional plane. If I set the new flowpath is XZ plane, I got again the error.

From your experience, could you tell me what should I do?
