What does it means that linked shape object is empty? I keep getting this error.

I made some changes to my model and now I just wanted to add the cylinders at the nose of the injector. Do I just use a datum plane and sketch the connector with the length, diameter and offset angle that I wanted? After that just duplicate with polar pattern? If you use a DatumPlane, you can model...

Now I wanted to do a solid quad mesh and I am using Instant mesh. Although I already chosen the option of pure quad mesh but when I exported it as OBJ file and then converted it into NAS file from FreeCAD and imported into AVL FIRE. But instead of quad mesh, it still shows triangle mesh and also is ...

Here a proposal for the first tube. Multiply it with a polar pattern. I have used a DatumPlane, because I guess you may want to make hole in it. Please note that the pad has two lengths. For the second DatumPlane I cheated a bit: I duplicated the first DatumPlane, detached it, and turned its Placem...

Can I just fill up the gap by linking the cylinder and the main body as shown in the picture? Like make a constraint on the main body and then link the points from the cylinder to the main body? Or do I need to do in from scratch?

Of course you can. You would continue with a new sketch at which you change the AttachmentOffset so that it is slightly skewed.

I see. Thank you for your help, I will try it.

I guess it might be the assembly function did not link it up properly so that when I exported it, it shows a gap. Because the cylinders have 2 different angles among the each other, or can I just continue construct like what is shown by Willem?

The cylinders are connected if according to CREO 4.0 because I was doing the model using that software and then import into FreeCAD. According the obj-file (freecad export) they are not connected. They touch and intersect, but they are not connected with the main object. See screenshot from Blender...

Thanks for your video. BTW how do you connect the points to the exact position because when I try to connect it, it seems to be always going off point.
