Hello
In GSD, I'm trying to orient a straight line in space. In other words, I want to construct a straight line by a point and a direction; And it is on this direction that I wonder.
I'd like to build a straight line with an apha and then beta orientation (to orient a straight line in space, you only need two angles).
I have a solution based on the construction of axis markers.
Is there a solution to build a oriented line of this type without going through the systems of axes?
Thank you for your feedback.
Hello
We can use the orientation of the compass to enter the 2 angles and use this orientation as the direction of the line.
But if you want to modify you have to redo the manip

Once you have put down the compass, remember to deactivate the selection by clicking in the blank of the graphics window (the compass must be gray not green)

Hello
If you have a lot of lines to create by entering two angles, there is always the possibility to create an optimized copy of an Angle/normal line to a curve which is itself an Angle/normal line to a curve.
If we accept by default that the first angle to enter is the rotation of a line on the XY plane with respect to the X axis and that the second angle is the positive or negative elevation of this line, we can have as input just a point and then the input of the angles.
See the attached video.

Super Franck, thank you for these detailed answers.
In total, for the moment, I now have 3 methods:
1) the method of using a direction given by the compass
2) the method in GSD using an angle with respect to a curve.
3) a third method that I do but which may be less interesting for the replayability of a skeleton from an axis system.
Regarding method 1 (use of the compass), I have, on the other hand, two small questions
1) On my side, I tried to redo the manipulation. I place the compass on the axis system, I click on the screen so that the compass goes back from green to gray-blue and then I edit the compass settings. On the other hand, on my side, unlike you, my room doesn't move at all when I add increments. I must have missed an important point in this apparently easy manipulation...
Do you have any idea what I must have forgotten to do in the manipulation?
2) Compared to this method, a disadvantage I see is the input element for the elements that will use this "compass direction". In other words, when you have navigated in the parents/children of the elements of a skeleton, the "compass direction" element is perhaps less robust than a classic geometric element of the GSD (points, line, ...). What do you think?
Thank you for your advice.
Hello.
Dixit: On the other hand, on my side, unlike you, my part doesn't move at all when I add increments.
The room should not move, that's precisely why the wallpaper click.
It is the compass that moves only after changing an angle and clicking on one of the arrow buttons (to the right of the angle in positive or negative).
Dixit: 2) Compared to this method, a disadvantage I see is the input element for the elements that will use this "direction".
The direction of the compass is not a parent link, it is not an input element, the direction of the compass is just used to calculate the components (Cartesian coordinates) X,Y,Z to define the second point of the line.
Great, in fact, I did put an increment but I didn't click on the buttons (yellow translation or rotation arrows) on the sides...
OK. Great, in fact I understood in the compass I put values at the level of the increments but I didn' t click on the yellow buttons with arrows for translation or rotation
