how do I manually edit curve point coordinates Sept. 11, 2022, 1:11 a.m.

Of course, in Houdini there are often many ways to get results. Perhaps putting in an RFE is the only way to go with a feature like this.

RFE is but one way....after that while you wait for the feature if it becomes implemented, you can make your own tool that approximates the same functionality you desire - after all that's Houdinis strength - making ones own tools for specific purposes.


I have to admit I'm tempted to create a python sop to do this. Creating the gui would require lots of learning but at least it would be a clear prototype to demonstrate what I would like.

while not ideal I found that Rig Pose is pretty helpful in editing curve points post creation both as Offset or Absolute values

check World Space to avoid it behaving like hierarchy
and then move points
if you want to set values in Absolute coordinates change Mode to Override

Tamte, I admit rigpose is usable for editing curve points post creation.
Override mode does allow explicit value setting.
However, Spreadsheet seems like the more intuitive user-friendly interface to enable manual editing of existing point values.
In the spreadsheet you see the original coordinate values which rigpose and transform does not provide.

I don't understand why spreadsheet panes of some Sops are haphazardly prevented from being able to edit the displayed values.
Engaging the SOP lock flag provides a mechanism to store spreadsheet edits.

You can go to Assets > Asset Definition Toolbar > Show Always and choose the previous version of the Curve SOP, that lets you enter coordinates as a series of XYZ coordinates. Alternatively, you can use the Add SOP to place points and then in the Polygons tab select "By Group" and it'll produce a curve from the points in the Points tab.

Jikian thanks for your suggestions.
Thing is, I would like to take advantage of the significant interactive improvements of the new Curve tool.
Also, the add SOP would only be useful if I knew the point coordinates before the curve has been started.
This topic is about manually editing the coordinates of the points of an existing curve.
