> Doesn't grouping provide the necessary functionality?

I am not trying to group anything. I want to move, say, a circle, with its centre snapping to a snap point or line.

I can understand the last sentence, like the geometry of a line acting as a guide. But do you have in mind some other software that would implement this? Also, about snapping to a point, I'm not sure I understand it. An illustration might help.

**SmartSketch, from Intergraph Corp. difficult to get.

**Example: draw a circle centred at the intersection of 2 lines. Or at vertex of a triangle, then copy it to the other. Generally, a figure is made of parts snapped to one another.

I was hoping to see some user manual with screenshots. Some 3D software have the same functionality, particularly action center: element in Modo: https://youtu.be/OEdtAPlYHFc?t=193

Enable View > Snap Guides > Snap to Guides and pull a helpline from the horizontal/vertical ruler. Your object will snap to this line. Right click > Edit Snap Line... allows precise positioning. Does this solve your problem?

You can't freely rotate guide lines.

Why would you need to rotate a snap point / line? Having the center anchored has been discussed recently in bug 154015.

Because TorrAB said:
"In particular, snapping to a line would help User to move the shape along that line."

You can already move shapes straight along x or y axes by holding down Shift or use guide lines like you proposed. Thus, I assume TorrAB means lines that point to any direction and not just straight along x or y.

I don't see the benefit in a rotated grid line when it comes to anchor at a point. And I don't read TorrAB's request as such. I wonder if the gridline tip was helpful or what exactly is missing.

It's not about a grid line or a snap line - it's about translating a shape along the edge of another shape.

@Armin, some guidance and statement of feasibility of implementing anchor "translation" along another objects line/polyline or even an arc?

do you mean like if you trying to use adobe illustrator when you use the direct selection button you can drag the anchor from a shape to anywhere you want?

Needinfo status not really needed, so setting to unconfirmed.
