The downloaded 3D model is partially displayed in a dotted frame, how to turn it into a solid? Mine

To be more specific, is there a picture? Added: Enable In Viwport is visible in the viewport You can choose to see if it works, or press F3 (Solids & Wireframe) to ask

Where's your Enable In Viwport? Talking about F3 . As long as you've learned 3D, you know.,If it's a good thing, I won't ask.,I didn't see that my picture is individual is an entity, and it's a dotted line?,The dotted line is to prevent the model from being too large.,So the display will not be stuck.。。

I asked someone to say that it was to select the right-click attribute of the object with the dashed line, and remove the dotted line display, but mine is the English version, so I don't know which key it is. Follow-up: Right-click on Object Properties and check off the checkmark of Display as box to display the entity or thank you for helping me.
