Thank you very much.
B-splines are at the bottom of the left table, conics have to be addded.
In the comments on the document opeBrain writes about the second sentenceThe grid For now open the ”Edit controls” and uncheck the ”Show grid” checkbox. The grid is only helping to place geometric elements. If you have ”Grid snap” enabled it suggests that snapped points have their positions already defined, which in fact they have not. So I prefer to have it switched off to avoid confusion.
I am unsure how to express the fact, that unlike other 2D programs the snapping does not define a point to stay at its snapping point, no constraints are created.openBrain wrote: This sentence is quite unclear to me.
Hi chrisb,
Code: Select all
If you have ”Grid snap” enabled it suggests that snapped points have their positions already defined, which in fact they have not.
Code: Select all
If you have "Grid snap" enabled, you may think that points will be permanently locked on the grid-points where they was dropped on, while actually they won't.
ATM I don't think so.

I hope for some clarifying words from the community.
The grid. For now open the ”Edit controls” widget and uncheck the ”Show grid” checkbox. Although the grid can be helpful when placing geometric elements, it is important to remember this:If you have ”Grid snap” enabled it might seem that snapped points have their positions already defined by the grid intersection, when in fact they are free to move. So I prefer to have it switched off to avoid confusion.
- Geometric elements placed at grid intersections are never secured to the grid;
- Separate pieces of geometry that share a point at the same grid snap location are not secured to one another, and they may move apart unexpectedly until a Constraint is applied between those shared points.
Part of that might be the fact that coincident constarints do not show up in the sketch, the same way that others do (with a symbol).
