Visualise 3D viewer's 'Spatial select' radius

[swilson27]

3D viewer (underneath main) has feature to select connecting neurons by spatial position, which are within a Euclidean distance from active node. To precisely select partners on specific parts of a skeleton, currently I am having to trial and error different nanometre distances (and upstream/downstream filtering) and post hoc cross-reference which partners I expected to see.

It would be great to instead visualise, seamlessly in the 3D viewer, what a proposed Euclidean radius around the active node would look like, such that we can be certain that we'll obtain the desired partners. Hopefully this, or a feature which does something roughly along these lines, won't be difficult to implement. Thanks!

Hi @swilson27, that's a good suggestion. I just added this feature to the dev branch. The dialog now adds a transparent green sphere around the active node with the radius set in the dialog:
