Can't export points when importing CAD in Blade modelor (DesignModeler) Answer: The problem was with the split in the blade solid . This works when you Boolean/unite the two solids. You will also need to ensure the last profile in the Export Points is No for export, as there is no intersection because of the tip gap . This will export the blade. 1. How is blade tip represented in Turbogrid? the original blade is flat at tip, Does the blade tip (Turbogrid) reprensented by the last layer loop cut near the tip? if so, then the blade geometry has been changed a little at the tip. 2. how to set up the tip shroud gap distance? I noticed the blade is extends to the shroud in Turbogrid, but the LE (green line in zx plane/meriondional plane) and TE (red) doesn't not. 3. How is the shape of periodic Boundary ( auxillary view ) defined? In my mode, the shape of periodic Boundary is highly twisted (not good for mesing), while the example...
