Could you tell me please the reason?
Please click the question mark on the top right corner and read the help
That symbol is showing that there is an error in the fillet part of the mirror feature. I haven't found the error yet but if you remove the fillet the mirror will create the rib. The fillets on the base of the rib work but not the ones on the sides.
Please tell me how did you get this conspicuous color?
This is by using the classic theme in 2016 and higher versions.
I use 2016-2017 student edition. I didn’t get this dialog box. You told me before. Just try to seek any other way.
Student version is generally SP 2 of the commercial version and this option was introduced with SP 3 of commercial version. So you do not see this option.
I have found that it is often best to wait to create fillets and chamfers until the end of the design. that way you do not have as many problems like you are seeing in this model. I was able to delete two of the fillet edges from the mirror and then place them later with no problems but even creating a separate mirror of the fillets after mirroring the rib did not work. However waiting to create the fillets until after the mirror feature worked with no problems.
