Greetings,

I deemed this question absolutely basic, since I encountered this problem within my first 30 minutes in Inkscape. However, googling the problem makes it seem likes noone else has ever had this issue.

While using the 3D-box tool, I set it up to only have a single finite perspective node. X and Y are locked to a certain number of degrees, while Z remains arbitrarily dragable.
I then summoned a guideline, to which I indeed managed to snap the Z-node of the box. This is where the trouble starts.

Dragging the guide line makes it disconnect from the node, the snapping seems to be lost. But I dont want the guide lines to only provide coordinates to line up elements on the canvas.
I want the guide to truly *snap* and *hold* the respective elements, in order for them to be dragged alongside all other snapped objects.

In this case, the guide line represents a horizon line, to which multiple boxes are lined up. So, Id like the guide line to hold onto all of these vanishing points.

Just a heads up, the dragging does not even work with simple rectangular shapes. They also remain in place while dragging the guide line to which they are originally snapped

Hope I explained the issue well enough.

Thank you, forum!

Snapping does not mean holding. What you describe is perfectly normal behavior in Inkscape. Snapping does not create any link whatsoever between two objects, or an object and a guide. Let's say it just makes your mouse cursor "jump" , that's all.

Thank you for your answer.

Would you mind explaining how to achieve the effect I described? I reckon that must somehow be possible.

I'm not entirely sure I understand what you want. Can you show us an example?

In general, if you want certain parts of a drawing to move together, you have to select the nodes involved, all together. But I'm not clear if you just need to move nodes, or entire objects (3d boxes).

But for sure, the perspective handles of the 3D boxes can't be permanently connected to anything, or moved with anything else. They can only be dragged individually.

Once we have a better idea what you're trying to do, we can give specifics.

Possibly they can be s napped together, and stay together, like gradient handles.... Hmmm.... I don't understand much about this 3d box tool. But it looks to me, as I make several boxes on the page, to test with, they all share the same perspective handes. No matter what part of the canvas I draw a box on, they all have their perspecive handles in the same p lace. And moving the handle for 1 box adjusts the perspective of all the boxes on the page.

Ah yes. Ok, I tried duplicating a box, and moving it over. Now it's perspective handles are different. But if I drag one handle over to another handle, they do snap together. And now they do move together! I can't seem to break them apart, except by switching to Selection tool, and drag them away.

It's 1 crazy tool!

I planned on creating a couple of objects. Namely, I tried creating two hot air balloons, with both having their perspective handle on the same height/spot. Then, I wanted to be able to drag said spot around, with the objects changing perspective accordingly, doing so until it looks satisfying.

Having perspective handles snap and hold together sounds nice, but whenever I highlight one box using the 3D-box-tool, the other one gets deselected, rendering its perspective handle invisible. Therefore, I cant seem to get them to connect as you described.

Tested in 0.91, here it works by editing vanishing points of a 3D box, all other boxes change accordingly.
If, you don't move the object in object mode, but only shape it with the box tool's options.

Hold the Shift key to make a multiple selection.

Usually you have to be using the Selection tool, for multiple selection. But in my testing, I was able to make a multiple selection with the 3d box tool!

However, if both boxes already have their perspective handles connected, moving the handle of 1 will affect the other box, even though it's not selected.
