I am trying to import textures and pre-built models from a site called Poliigon. The site has thousands of pre-built PBR models and textures. These models and textures are much better than what you find in the Chief library or in the 3D Warehouse. The file types are primarily JPEGs. When I download these files and unzip them, it breaks the texture down into the individual attribute files, such as normal, roughness, etc. When I try to import the texture or model into Chief, it does not recognize the file type. Downloading into Blender, SketchUp, or 3Ds is not a problem. Has anyone imported files from this website before? What is the correct procedure to import these pre-built models?

I had my first experience with curbs today. Very frustrating. No matter what length I drew the curb, it would run out and attach itself to another curb or a terrain boundary. Is there some way to prevent this from happening? Also is there a way to delete a section of curb where it passes through a roadway?
