Hi. I want to fix a gear in space but let it to rotate. In Inventor I can make assembly level axis in the center of a gear and fix axis in space. And then mate gear to it.
In Solidworks I see no "fix" option for axis. So how would you do this?
Why can't you create planes, line, etc that allow you to create an axis and dimension that where you want or don't dimension it so it floats? Create a 3dsketch and make a centerline and use that with no dimensions to create an axis if you don't want dimensions to it.
You can use temporary axis for mating, view - show/hide - temporary axis
But I need to mate this temporal axis to something fixed in space. And I'm trying to figure out what this could be without creating extra part.

Create an axis or sketch line in your Assembly and use that.
At this point I found that layout sketch is closest to what I want because I can drag it without entering edit mode. Then I create axis using point on layout sketch and one of the assembly planes.
Does your gear have a hole through the center that you want it to rotate about? Assuming it does then turn on temporary axis and then mate the axis that goes though the hole to the plane you want it to rotate on, you will need to make a second mate so that the gear won't move linearly along the axis.
If you don't have a hole then you need to create an axis on your gear that you want it to spin around, once you do mate that axis to the plane like above.
I don't understand this
mate the axis that goes though the hole to the plane you want it to rotate on
Is it possible to mate axis to plane?

This is such a fundamental question. You will do yourself a very big favor if you invest a little time in going through the SolidWorks Tutorials (look under the Help menu and you will see it there). Since you are already familiar with 3D modeling the techniques will be familiar to you, but the big benefit is that you will learn the very easy ways to do those things in SolidWorks. If you are just interested in making a gear rotate in an assembly file then all you need to do is mate its temporary axis to the origin (coincident mate) and then pick a face on the gear perpendicular to the axis and make that face parallel to one of the assembly planes (parallel mate). But if you are having such questions then you will have many, many others. Do yourself a favor and shorten your learning curve by utilizing the built-in tutorials.
Welcome to the forum. Ask good questions and show your work and you will get good help. And please also read this post: Some very important steps if you are a NEW FORUM USER....
Why are you making it sound like his fault for asking a valid question?
"Is it possible to mate axis to plane?"
No, simply mate the temporary axis (view>hide/show>temporary axis) to the origin and mate the face of your part to one of the planes. Then your part will be "fixed" but can still rotate.
The problem is that I don't want to fix it at origin. I want to fix it where I want.
Yes you're right. I can constraint gear axis directly to the 3D sketch line. And I can move it and fix it in space when I want. Thank you.
If you can't figure it out - attach your assembly here and end all doubt.
