Hi Carolin ,
there are a lot of options ,
colour wise you could use another appearance and change the colour , feel free to google the material you are looking to represent and use the colour dropper to grab it right from the google webpage.
you could also use textures to achieve the look you are going for as well.
I would look to my.solidworks.com for some free tutorials on applying textures and appearances
also if there is PV360 appearance that is close (there are quite a few brass appearances) they are available in visualize 2018
As Scott mentioned, there are the PV360 appearances in Visualize now, both 2017 & 2018. I use them often and I think they are pretty good. A little tweaking and they look pretty darn good to me.
I've included a screenshot of where they are found in the cloud appearance database in Visualize 2017.
Thank you both so much
I didn't know about the SolidWorks appearances before. You made my day.
Carolin, if you look at the upper right of the window right under the Libraries tab, you'll see a little white down arrow to the left of the disk icon. Click that. You'll probably like what you find under there. And again, you'll have the local disk library of the different categories, or you can click the world icon to download from the cloud library.
