Curved Shapes Workbench

[pointdee]

Thanks for this Chris and apologies for not trying this sooner (the job I needed it for didn't happen so it dropped off my radar)

I've just tried to use this using my sample attached. I select Sketch001 then Sketch003, click on the CurvedPathArray tool and I get a new CurvedPathArray created although this has an exclamation mark. The Report View has the following information

Part::FeaturePython / CurvedPathArray001: Links go out of the allowed scope
Traceback (most recent call last):

I have fixed a bug. You can update the workbench and try again.

If you want to use Sketch002 as a hullcurve, add a bottom line to the sketch - connect the open ends of the spline with a line.
To get the scaling for all array intems, set Scale X and Scale Y to false.

I've updated and tried again but basically get the same error message

Part::FeaturePython / CurvedPathArray: Links go out of the allowed scope
Traceback (most recent call last):

<class 'TypeError'>: Base.Quantity and int cannot be mixed in Quantity.__sub__.
Make sure to use matching types.

The line numbers in the error message are different to before so I guess this means I'm using the newer version.

All I've done is select Sketch001 then Sketch003 and clicked the CurvedPathArray button

Thanks again

The error occured in version 0.18. I was working with 0.19 - no problems there. I made a small change, now it also works in V 0.18. Please update again.

Works for me now. Thanks for your tools and your persistence

I have tried several times to install this workbench, each time addon manager shows that it is installed but it does not show in the drop down list.
Any suggestions?

Are there any error messages in the report view ?

Hi,
I'm trying to trim a surface with CurvedArray. Two things I can't understand:
1. The surface carried out is downed, but should it be? (red arrow)
2. The surface seems not follow the mandatory boundaries. Where the surface should be empty, it's be present and vice versa (blue arrows)

1. The surface carried out is downed, but should it be? (red arrow)

Both hullcurves are in the XY plane. There is no extension into the Z direction. This is why the Curved Array tool does not do shiftings in the Z direction. You can add an additional sketch with a straight line that connects the two other hullcurves. This will do the up shifting.

2. The surface seems not follow the mandatory boundaries. Where the surface should be empty, it's be present and vice versa (blue arrows)

If you select the view from top, you can see how the array elements are arranged between the hullcurves. The surface follows exactly the mandatory boundaries, but maybe this is not what you expect.
