In the attached file, I want to rotate the semicircle (in blue) from its base point at the bottom to the sky blue point. For the moment I can do it with the rotation function but this function requires to identify the rotation angle which is quite tedious insofar as these are not common angles and I have to measure them each time (I have several rotations).
Is there another way to apply this rotation? For example, by selecting the 2 axes that make up my rotation angle?
I tried to move the trihedron which is placed in the center of the rotation but it doesn't fall on the desired angle.
I'm not sure I understood everything: but could the "circular repeat" function be suitable.
So your blue sketch would behave like the letters G and C
On the other hand, if it is your semicircle that rotates on itself (as if it were rolling on the arc of the great circle) going from the current point to the blue point, you should specify the number of turns.
Also specify whether it is the sketch you want to rotate or the object (the body).
If I understood correctly, the half disk must be halfway between 2 letters (which are not the same width). So the circular repetition is not suitable, I had thought of a dot repetition but I'm not sure you can rotate the sketch along the way.
If it's to place your text and you dot in a circular way, why not make a circular sketch in construction line and use the text function in the sketch by selecting the circular sketch and doing a material removal as you do. See PJ in SW 2016 for example
It is to the sketch that I want to apply a rotation (which would drag the semicircle over the large circle where the letters rest, up to the sky blue point).
the "circular repetition" is not suitable because the angle is never the same; indeed, to write the letters, I used the text function of Solidworks and the space between letters is not the same (for example between G/C and C/R) and the width of the letters is not the same either. So it's a real headache.
I want to rotate my semicircle along the same arc as the one where "30.31°" is indicated, so with the center of rotation located more (out of the field of the drawing).

Yes, that's exactly it, "the half disc must be halfway between 2 letters (which are not the same width)."

So it's true that I didn't think to make the dots in text mode because I apply, to the dots, the Revolution function to get half spheres between the letters (themselves extruded).
To give you an idea of what it looks like, attached are 2 images.
I understand our confusion (mine anyway) because for what you want to do is the revolution function
"Revolverd boss base" The rotation function is another feature that has nothing to do with it :-)
The easiest way is to put a construction line equidistant from the two letters (by hand sorry). This line will serve as an axis for the "Revolverd boss base" revolution function.
@ Zozo_mp (sorry for the mistake on your username in the previous post)
Indeed, I did a revolution (which was not a problem for me) but I was talking about rotation:
- To do this, the function requires: Entity / Center of Rotation / Angle of Rotation
- instead of indicating rotation angle, I was trying to find out if we could designate with the pointer (directly on the sketch) the axes that form the rotation angle... but obviously not...
@ stefbeno
I didn't know about this function and I'm interested in it!; So I'm going to test what it looks like and keep you posted. Thank you for taking the time to sketch :-)
@gt22
I wrote the letters with the text function of Solidworks, so the interval between letters has not been changed, and this may be an approach to be explored....
It is indeed a medal and the idea of changing the position of the ring is interesting.
I work under SW 2018.
@ AC Cobra 427
Indeed, I just quickly tested my text with a period in 2-letter intervals and it is placed right in the center :-)) So I'm going to go back to this base and see what happens.
I'll keep you posted and thank you for all your great ideas!
I have just finished drawing my text and the stitches as follows:
- by writing the text with the "period" but instead of writing ". G.C.R.E."I created each letter distinctly with a dot (to allow the letter to be moved on the arc of the circle because without the "dot" the letter remains fixed): ". G" then ". C", etc...
- This way, I was able to easily position the 2 central letters (C and R) in relation to the vertical axis of my medal (so I don't need to move the bail anymore :-)) and transfer the space between these 2 letters to the rest of the text;
- to perform the extrusion of my letters it still made me before the operation "Dissolve sketch text" to remove the dots that had become useless;
- And finally, the "Sketch-driven repetition" function was useful for me to create my points between the letters (sketch, revolution, sketch repetition) as indicated by AC Cobra 427...it's exactly the function I needed:-)!
