From three offset sketch profiles I aimed to make a curved loft. The radii of the centre sketch is 75mm, and 25mm for the end sketches. The guide curves are splines on a side plane running along the edges of the circles connected by a straight line across the bottom. As observed in the preview, there is a strange gap on the right side of the product. This is not just a preview or graphics error from the viewpoint, when the loft is approved it results in the asymmetry the same and can be observed from all angles. Is there any alternative way to perhaps model this without error? The aim is to replicate the basic shape of a curved soft drink bottle e.g sprite or in this case what looks to be a vase. I will be putting a slit in the model and 3D a few to create a wind harp. Any input is appreciated, thank you
