Feature request for the sketcher-workbench

Postby freecad-heini-1 » Tue Jan 15, 2019 8:56 am

Feature request for the sketcher-workbench:
Compared to Chrisb Sketcher tutorial on page 28:
slot_dimension_sktecher_tutorial.png
slot_dimension_sktecher_tutorial.png (31.09 KiB) Viewed 867 times
It's a bit complex to reach this dimension 30mm, two points onto the arcs, and they are horizontal to the arc center points.

I wish to have such a dimensioning tool, tangent to the arcs:

For construction lines I wish the possibility to change the draw style like in the view tab.

Second wish / request, it concerns external geometry. I wish that if I select external geometry, that it's not needed to redraw the shape.
Sorry my English is so lala, I hope my animgif help to understand what I mean:

partly similar request as mine last week: see https://forum.freecadweb.org/viewtopic.php?f=8&t=33369

Hi Wilfried,

I can make a finite number of different distances between "lines" tangent to the arcs, having each a different length. For defining what you want, I think you need more than just saying "tangent to the arc", either it is tangent to the arc at a given point, or tangent, where the tangent is vertical/horizontal.

I am not against having a better way to do this. But I am not sure of exactly what.

This should happen during v.19, as it seems it is possible to arrive to a good implementation.

Most cad's have the ability to automatically select midpoints... I think that would work quite well also in the first example (request).

Offset, rotate, scale and midpoints would IMO be all nice improvements to the sketcher :roll:

Hi abdullah,
I mean horizontal / vertikal or to a defined line / direction. At the moment it is a bit work to dimension the 30mm, for future I wish to select the two arcs, horizontal, that's it.

O.k. at the moment the draw style of a construction mode element is solid. I wish to have the possibility to define the draw style inside the sketcher to dashed, or dotted, or dash-dotted. So that inside of the sketch construction elements are not only blue, in addition they are for example dotted.

I am not sure about the arcs, because it looks to me a non-intuitive workflow. I do acknowledge the need/advantages, but it does not appear to be intuitive for the user. It needs more working to arrive to a seamless approach.

About the drawing style, I am not sure what can be done. But it should be a matter of investigating.

Feel free to add a couple of tickets for feature request to these two (the other two already have tickets), for target version 0.19. You do not need much description, just link your post above. This way I will have an active reminder. ;)

We have this almost nowhere else. There is only the use case point-to-line-distance which can be seen as similar.

Although it is not the most comfortable way I like saso's idea of a midpoint on the arc. That would work seamless for a tilted slot as well.

Good example Wilfried, midpoints will obviously not help here :)

for better understanding:
Definitely yes. Much better understanding. So what you are proposing is an overload of the horizontal/vertical distance constraints between curves. This seems well defined and doable. It is likely I will make it into v0.19. Put it in the tracker so that I do not forget.
