BUG : loss origins in the rotations of aligned models

[IMDIMA]

For two-color printing, after loading two 3D models I select the two and "move" and "align together"

Then if I want to rotate the two pieces (selected simultaneously and / or separately) for easy printing the alignment of origins is lost.
Even if I trie to repeat the alignment in this new position that does not work

I has also tried to make first rotations on 2 models and align origins after but it did not work either

The possibility to create a group with two loaded models and apply to that group all possible transformations would be a great help

(sorry for my bad english i'm so french ! haha !)

Select both model. Then choose Model -> Merge Selected Models.

The two models will be one group.

You can rotate or move them. They will move together.

If you want to let them to be separate, you can choose Model -> Auto Ungroup.

Then you can move them separately.

Thank You for your quick and documented answer

If I use "Auto Ungroup" after "Merge selected models" and "move/rotate them together" as you told me I often find myself with more than two models.

I must then remerge the right pieces together in order to assign each model from the extruder corresponding to it, it's tedious!

I return to my original question: Why after "align together" we lose this alignment during rotations? If this could be changed would bring much comfort to the management of two colors prints


-thank you-

[Vicky@Raise3D]

Alignment is just commend of adjusting position which has the same priority of Move and Rotate. So the command you select after will be carried out directly. They don't have limitation to each other.

I recommend you to choose the nozzle after completing the position adjusting.

If you have more than two models at one time, there can be several groups in one slice. You don't need to select all models to merge at one time.

Let me know if you find it easy with those 2 stl : https://we.tl/LZjn6Cit54

For exemple I want to print them upside down, one color for each file

When I "Auto Ungroup" there is 337 parts, not easy to allocate the right parts to each of the two extruders!

maybe there is a trick that I did not understand... ?

[Vicky@Raise3D]

This model seems don't need Merge.
Select both and you can rotate them together after alignment.

[IMDIMA]

if you look more closely you'll see that the two models are no longer aligned...
and if you don't see it in this position try upside down

[Vicky@Raise3D]

We are so sorry. The rotate function needs to be improved. The merge function is just out of expediency. We need to check whether we can make the rotate better.

[IMDIMA]

ok, good luck for your research

if I could explain in French I could give you some ideas but in English it's very hard! sorry

Nevermind I try :
I think that just two things should be clearly separated in functions:

1 -> group / ungroup (to apply transformations to selected models such as zoom, rotate, move, align the origins)

2 -> merge / separate connected mesh (what you call now "Auto Ungroup")

Hope that help

[Vicky@Raise3D]

Would you like to explain more details?

I'm not very clear of the difference between between 1 and 2.

One tip that can be useful if printing a set repeatedly is arrange it on the bed just how you would like then save the whole thing as an stl in ideamaker.

[Vicky@Raise3D]

ideaMaker can only save one stl one time.
