Curves workbench

[CadX]

Hello Chris.
I installed Curves Workbench but some commands seem not available like that..Although their icons seem available on toolbar and menu.

Line,
Mixed Curves,
Split Curve,
Iso Curve,
Gordon Surface,
to Console,
Sublink Editor,
Compression Spring,
BSpline to Console

Thanks for your support in advance...

Hello,
Some tools need an active document to become available.
Some others need a selection.
For example, IsoCurve needs a face selected, MixedCurve needs 2 objects selected ...

However, if the tools are still no available in these conditions, then I'll need more information from your setup : FC info, how you installed CurveWB (new install, or recent update ...).

Hi Chris,
I've got a bug with line: line doesn't at the right position.

As you made this simple and nice feature, a feature could be useful: Arc (3 pts and 2pts+radius).
Thanks if you have time.

must check out too: pipe doesn't work anymore.

... here (FC.18.4) it works.

You use Base.X Y Z instead placement. But placement is used for all objects isn't it?
Is the right position should be (Base.X+Placement.Pos.X)?
placement could understood as an offset. I'm right?

[hammax]

... if I use Placement to change the points position, I get the same "displacement" like you described in your post.
It's either a bug or placement is not the right tool.
Changing the points position by the basic coordinates works.
Caution, I'm using an older version Curves_v0.2 because the new version doesn't work anymore on my FC.18.4.
This was the hint, I tried to point on here.

I've got a bug with line: line doesn't at the right position.

It should be fixed now.

Arc by 3 points : why not
Arc by 2 points + radius : this already exist in 2D (sketcher and maybe Draft), and it is not enough to define a single curve in 3D.

must check out too: pipe doesn't work anymore.

Would you have a test file please ?

pipeshell:

Code: Select all

You must select:
- in the 3D view, the edges that build the sweep path
- in the Tree view, one or more 'pipeshellProfile' objects

line: seems be ok, thanks.

arc in draft: it's a not parametric feature
