Spline Ghost Grips

patrick_smith2X3ZH — Mon, 14 Oct 2024 19:57:30 GMT

Switching between vertex methods (fit and control-vertices) may result in tugging from invisible grips that only appear when switching back.

This issue can be reproduced with the following steps:

Draw a spline (fit)
Switch to "control vertices"
Switch back to "fit"
Add a vertex

The auto-generated control vertices turn into "ghost grips" that are not so easily removed. Is there a technique for repairing splines like this? Thanks.

Can you show us in a couple of screenshots?
Also include screenshots of your AutoCAD's ABOUT and GRAPHICSCONFIG commands pop-ups please.

@patrick_smith2X3ZH It's not clear what action you are taking to "Switch to "control vertices". Are you giving the splinedit command with the intention of editing the CVs or the Fit points? In step #2 are you editing a CV (eg., location or weight) before you go to add a fit point?

CVs are an intgeral component of spline data. You can hide them but they will always affect the shape of a spline. They will alays "tug" on the spline.

When creating a spline with Fit points, AutoCAD automatically determines the location and number of CVs needed to produce a spline that passes through the fit points.

Use the Properties panel to easily see, hide or edit CVs.
