Curves workbench

[wmayer]

Whow, amazing. Werner is a great programmer. Such nice stuff with just two icons. I'm very impressed.

Kudos go to ChrisG because he added the latest feature.

Please let me know, how do you figure out such cool things?

It's basically a matter of trying to use as many functions of a class as possible. The most difficult point is to avoid to make the UI too complicated.

@microelly:
projektion of the (blue) sketch on a cylinder (red curve).
Is that what you are looking for?
workflow:
select sketch in model-tree
click on cylinder-surface in 3D
hit the "map sketch on surface" button
projection.FCStd
projektion.JPG

Thank you but
no, I was looking for a "simple" parameter set for such a curve, in this case for a solution with only 3 or 4 poles to get the 1/4 helix.

...@Chris_G, please explain to us the usage of your newest Icon:

"Profile-Support_Plane"

Next question: is there a possibility to change fontsize and fontcolour in your Info-HUD-Feature.
I already could change it per hack inside 1.Icon-Tool (Bspline) .py-Macro.
In HUD there are at least two places, where fontproperties are defined. But here my hack-trials didn't succeed.
( I need a bigger font and a bright colour , because I have a darkblue Background, like Catia)

Hi,
The goal of this tool is to create a support face ( for a sketch object ) that stays clamped to 2 rail curves.
Let's say I want to create a parametric arched-top guitar shape between the white and orange Sketcher curves :

- I go Top-View (View Direction is used as the direction of the support face) and I select the 2 rail curves, by clicking them where I want the Support face to be
- I activate the tool and I get this support face that is parametric and can be moved along the input curves with the Parameters properties :

- Now, I can use the top edge of the support face as an external geometry line in a sketch, and constraint my BSpline curve ends to this line.

- Finally, I can build a surface with the boundary curves and the profile sketches as "unbound edge" constraint curves.
This surface is fully parametric and can be stretched and modified by editing the sketches.

For the "BSpline curve" tool ???
This tool is fairly broken, I should remove it.
But you can modify the appearance of the HUD on line 54 of "bezierCurve.py" :

Code: Select all

self.Block1.setFont("Sans", 10.0, (0.,0.,0.))
#Function arguments are (FontName, Size,  Color)

Whow Chris_G, amazing. Now it's possible to create a surface with inbetween curves. Very great.

works fine for me.
I can draw on the faces as usual.

I still have to inspect the uv-space conventions to handle nearly overlapping faces. great.
