Good evening; I'm trying to create a "warhead" type shape (nothing military, it's to make a steam engine fairing in modeling) using SW's "Bossing/Smoothed Base" function. Sketch 1 (E1 / front plane) has a sketch composed of straight segments and a semicircle: E2 (top plane) is composed of a spline and straight segments; finally E3 (right-hand plane) is supposed to be the guide curve, also a spline (see image).
Of course, the smoothing fails. In a previous version, E2 (top plane) was also composed of line segments and a semicircle - and the smoothing worked. I deduce that it's the presence of the spline in E2 that makes me swarm. But why and how to correct the (warhead) course ;-) ); I don't know.
I read the posts (including the one of the violin back by GT22), I forced the "proportional" option as well (different combinations), failure as well.
Your insights to create this volume will be precious. Good evening and good Sunday.
I never figured out how to have the color sketch lines. I manage to do this inside the sketch but the color no longer appears once the sketch is closed. I manage to color the faces as in the image above but not the sketch. (RHAAAaaaaaa)
As I start from the principle that if I can't use a function in 10 minutes (20 minutes if someone explains it to me a little) it's bad so in this case I don't try to color my sketches anymore.
However, as I'm "Open mind", if you tell me how to do it, it will be an opportunity for me to decetinize myself hihihi and see the screw in color
Ok well seen Zozo_mp ... yet the segments are present in the 2 sketches but they do not seem to be taken into account ... weird ;-(
One last question: the kind of "line of force" (2 green handles and a thin black line) that appears when you activate the smoothing function, what is it used for and how do you use it? I can't find an explanation for its use.
Oh and another thing that bothers me about spline handles: a) it seems that we can only constrain the direction of the vector on a vertical or horizontal, not on any axis of direction - is there a solution to constrain the vector on any axis?; and b) how to make a spline handle symmetrical so that the length of the vector is identical on both sides of the point of contact with the spline itself.
for your splines you have to distinguish between 2D splines and 3D splines. You understood that 2D splines can only be piloted in two dimensions unlike 3D splines ;-)
You have several ways to pilot your splines.
I had made a mini tutorial on the subject some time ago but as the versions of SW have evolved, we would have to add the new possibilities. Hoping that some tips from this document will be useful to you. I put it in PDF because not all the colleagues on the forum have Word.
For the smoothing function I'll answer you a little later. ;-)

I made you a mini tutorial on the why and how of these handles. Tell me if this suits you as an explanation.
