Hello!
I have an urgent model to make, and I am stuck with this problem:
I need a slide (toboggan) to drive discs from vertical to horizontal orientation (picture "current").
First I tried to solve it using loft feature, but I haven't got the solution I seek, I don't have full control over my loft feature (picture "loft").
I also tried to make couple of sketches which could help me control my loft, it,s not good again (file "toboggan").
Any ideas how could this be solved? Please help!
Cannot help you much with the part you are trying to model but maybe with the loft.
Delete the loft feature but leave the sketches, create a loft again but be careful what part of the sketch you pick to use it.
I am sure there is a rule about how it gets done but I keep picking points on the second sketch until the loft looks like I think it should.
You can also add guide lines to the loft to curve it for instance. If you connect the 2 sketches that define the loft with an arc the loft will follow that arc.
Again I experiment until it looks like I think it should.
Hope that helps
I know what you mean, I am doing the loft at the same way, picking the points until I got the picture I want. But this one is not working. I is not looking like I imagine it should.
There may possibly be too much difference between the sketches to allow a proper loft.
I have found even some small rads in the corners of one of the sketches helps the loft shape generate correctly.
The right side upright on Plane6 may be too drastic a change, very abrupt change from plane5. A guide curve drawn as a spline in a 3-D sketch connecting the very lowest points of the sketches may help.
Ivana,
In the preview for your loft, look at the connectors and adjust their position to get the shape to flow properly. The initial position of the connectors is determined by where you pick the profiles. The first connector connects at the positions you pick on each. If you pick "opposite" corners, then your loft will have a twist.
If you can do it without too much work, it is a good idea for your profiles to have the same number of elements (lines, arcs, splines). That makes it easier for SW to connect the profiles. Basically, the end points of the segments will be connected. If you have the same number of segments and they are spaced well around the perimeter, it is much easier for SW to generate the loft. You can split lines and arcs on the curve with less elements to even them out. You can also split lines and arcs on both profiles to get a better match.
The Boundary Feature is preferred in most cases to the Loft.
