rotation de l'extrusion et création d'un plan de dessin ex nihilo (by Frédéric)

bonjour.

je crée un cylindre
je veux créer un second cylindre avec un angle de 30° par rapport au 1er
impossible

si je fais le second et que j'essaye de contraindre les deux axes avec un angle, il considère que la base est liée au plan du dessin, et donc refuse de basculer selon la contrainte

en fait, c'est la définition d'un plan de dessin qui est très confuse dans vos tutoriels

comment s'y prend-t-on si on n'a pas deux axes et un point comme dans votre exemple?

merci

Select "Anywhere in 3d" from the "Sketch" menu, and then you should be able to draw construction lines for your axes freely.

thanks for your answer. but how do you "constrain" your new drawing plan?
I mean, if you draw anywhere, you then need to give some directions for instance. And I do not understand that.
thanks

and you can not draw an arc in the "anywhere drawing" function
thanks

Yeah, you have to define a workplane if you want an arc/circle. For constraints, you can try parallel or angle constraints between the construction lines and the coordinate axes. For example, sketch the cylinder axis line and call that z', and then constrain it against the coordinate axes. Then sketch x' and constrain it perpendicular to z', and sketch y' and constrain it perpendicular to x' and z'. Create a new workplane group using x' and y', sketch the circle in that group, and extrude.
