is macbook m1 is good for civil engineering related softwares

According to specs apple m1 is a great device but I shall inform you that there is no analytical software like etabs, sap or similar software available but you can use cad and 3ds with apple devices. There is an option to use etabs and sap by using virtual machines but I do not suggest that. Because your device will get slower. Hope this can help you.

Ask your engineering department or whomever you are working with. My grandson's school of engineering said Apple's were fine, but the programs were built around Windows. The department furnished Windows apps, Mac owners were on their own as to finding apps and paying for them.

He chose Windows, but will be getting the Mac of his choice from me after graduation this Spring. He has never regretted the decision to go Windows to better fit his program of choice.

I would suggest you check with the individual vendors for the software you desire to use to determine if they are compatible. You will get a much faster answer that way.
