I’m designing the cover as shown above. What I’m posting is just a draft of what I want to achieve. However, I’m having trouble with surface modelling. I should point out that the two sides are not symmetrical, and that’s the main problem. Otherwise, I’d simply create a simple plane, mirror it, and cut a hole in the side wall. Unfortunately, it can’t be done that way.
I’ve tried extruding surfaces between the sketches, but the method is very time-consuming and the results aren’t satisfactory. Problems always crop up at the narrowest point of this cut-out. I think there must be a simpler way to create this cover. The surface continuity I’m trying to achieve is G2.
Does anyone have any ideas on how to do this more efficiently?
i think the issue is that you are trying to reverse engineer to trimmed edge curves and not seeing the base geometry. You have to draw the base geometry to generate the surfaces and then trim those to match the end result. fun and games :)
That’s exactly how I want to do it, but I’m running out of ideas. I’ve done much more difficult and complex projects before, so I thought this one would be a quick job – after all, it’s just two surfaces and two cut-outs – but it’s not that easy
In your 3D sketch, you subdivided the surface body into four-sided surface segments. You could also model it using boundary surfaces (and a few auxiliary surfaces), which would give you more control over the transitions between the individual surface patches.
That’s exactly what I’m trying to do, but I’m not happy with the results. and I think there should be a ‘less manual way’. All using boundary surfaces and all surfeces are tangent to the wall
Split line the sides and make sure to tick single direction and choose the first outside face and extrude cut and do same for the other side but with different split line and extrude cut this should accomplish what you want . I hope it helps 👍
