Hello, how to combine those all shapes together in one shape, and do the extrude ?

It’s not clear what kind of answer you’re expecting. As the designer, it’s up to you to decide how to combine things. If you know what you want to achieve but don’t know how to do it — start by telling us what exactly you’re trying to accomplish.

For instance, I could say: ‘Draw a circle in the center that join all parts.’ That would technically answer your question — but most likely, it’s not what you really want.

In that case, I already gave you the answer in my previous message.

Thank you for clarification, but i want to join all those parts to be in one group and then if i use extrude on one part other parts will be extruded as well.

Even with circle i cant extrude them

I’m not seeing any option to extrude

That’s why I said tell us first what yo want.

There is no such function as grouping in Shapr3D.

That’s because you’re in sketching mode. To extrude you need to be in 3d mode.

You must select the faces (faces are closed elements like circles or rectangles or any group of lines that begin and end at the same point to create a “closed shape” area.)

“Closed faces” will be seen to change color from the background. Any closed face is extrudeable.

Multiple faces do not need to be touching to also be extruded at the same time. You can select multiple faces and extrude them at the same time (Shift + Mouse click to select more than one face for example).

For multiple faces to create one body they must be touching along a side or area. Faces touching only at one point will not extrude into one body and cannot make a valid single body.

You must “exit sketch mode” to extruded faces. You must select ALL the faces you want to extrude.

OP is comparing vector program concept and 3dCAD Sketching.

If all your drawing/sketch is in the same layer it would be considered grouped, joined. There is no union boolean/mask of sketches. Example you can’t make a empty hole in your sketch, you just get out of sketch mode and into 3D mode, select everything except the hole to extrude.

If I could explain sketch layers in Shapr it would be more like layers in Photoshop.
