What tool can be used to create a simple 3D animation?

Question

3D

There is a 3D model of some complex object.
It is necessary to create an animation of the movement of its individual parts.
For example, as in a children's designer, the operation - tighten the bolts - and the bolts that hang in the air fly to the right places. Something like (in the picture, apparently, the bolts are unscrewed):

Is there a simple tool (for a person who is not very familiar with 3D modeling) that allows, relatively speaking, to select objects on a 3D diagram, indicate where and where we move them, ideally, indicate the nature of the movement (straight, spiral, etc.) and record the animation?
Thank you.

Answer 1

Such a question in different forms and about different things is constantly asked here. I'll try to explain what the problem is with it.
Imagine that your knowledge now is a "unit". The knowledge that is needed to solve this problem, regardless of the software, is "ten". Together with the internal features of a particular program - from "12" to "20". At the same time, most programs require somewhere "13", because the programs are still created in such a way that it is convenient to work in them. Thus, you will not be able to save on knowledge, say, six steps. You still need to go up to about 12. And 12 or 13 - it doesn't matter.
An important point: the narrow specialization of the program sometimes allows it to be simplified, for example, architectural editors do not have editor functions for complex universal modeling. But your task does not belong to such a narrow area.
Based on this, we can conclude that you will spend more time tinkering with any program than it makes sense to spend, because by doing what you know how, you will earn much more during this time in order to pay someone who can do it quickly than you save by trying to do it yourself.

Answer 2

It can be done if I understand the question correctly. You need Cinema4D. Importing objects. Let's go to frame zero. Select the "bolt" and hold down CTRL (do not move the object.) With the CTRL held down, click on the red key. Move the slider on the timeline by 50 or 80 frames. On this frame, we simply move the object with CTRl released and press the key. The smaller the frame, the faster the animation goes. Voila!

Answer 3

Yes, there is such a tool. It's called Blender! Within the framework of what you wrote, it will be quite easy to master.
