greetings. i use autocad like a one year and i am trying learn inventor but its very different to acad. i cant found easy suggestions answer.
how ı copy marked object to marked point?
2nd suggestion is
how can I draw line in sketch to other workspaces sketch? Workspaces have different Z axis.
One thing to remember is to fully constrain the sketches. By that, if you look in the lower right hand corner of the screen in a sketch, it will show you how many dims or constraints are needed to fully define the sketch.
Have you had any formal training with Inventor? Also, it appears that you are trying to make an assembly. With Inventor, you can make parts, and then make an assembly where you will constrain parts together to make an assembly which in turn will give you are parts list in a drawing to identify what each component is. With your current method, if you make a drawing, you will not get that. There is another workflow which follows what you are doing which is called multi-body modeling. This will allow you to create what would be individual parts as separate solids, and then use the "make components" command which will then take each solid body, turn it into a part and make an assembly which will ground all the components in place.
I'm not use what your ultimate goal is here, but for practice, I would work on making each part its own ipt file. Then work on constraining to make a functioning assembly. For example, the U shaped frame as one part, the connecting bar as another part, the round bars as another and so on.
Make sure to work on full defining all sketches. You can sketch out the shape you want, then make sure to go back and add dimension. Also, Inventor sketches will automatically create geometric constraints when sketching if you watch the screen, but if something didn't, you will need to use sketch constraints to define what movement you want.
Attached is a simplified version of the U shaped base. I made it to where the origin planes will be centered in the U-shape.
Hope that helps.
