Facility outline

Dear freelancer, I've attached a sketch of the work that I want you to do and I'll try to put in as much details to make things clear. All the figures in PDF represent the same Project. The project is a rectangular research reactor (shown in the figure with 4 black circles), centred in the middle with 4 sides A, B, C, and D. Each side has 4 cylindrical beam ports coming out from it. The first circle represents only the end of the beam port, and the start of a smaller cylindrical tube going to each facility numbered from 1 to 8. These tubes have a length of 30 m, making the outer circle with a radius of 30 m. Each facilty covers a certain angle from this circle and has a certain number of tubes going to it. Facility 1 (SPEC1): angle=90, 4 tubes going to it. Facility 2 (IMG): angle=22.5, 1 tube. Facility 3 (SANS1): angle=45, 2 tubes. Facility 4 (SPEC2): angle=22.5, 1 tube. Facility 5 (DIFF1): angle=45, 2 tubes. Facility 6 (REF): angle=67.5, 3 tubes. Facility 7 (SANS2): angle=45, 2 tubes. Facility 8 (DIFF2): angle=22.5, 1 tube. The legend is as following: SPEC1: Spectrometer Facility hall 1. SPEC2: Spectrometer Facility hall 2. SANS1: Small-Angle Scattering Facility hall 1. SANS2: Small-Angle Scattering Facility hall 2. DIFF1: Diffraction Facility hall 1. DIFF2: Diffraction Facility hall 2. REF: Reflectometer Facility hall. IMG: Imaging Facility hall. The shapes I've drawn for the facilities are rectangular arc and connected but they could be with different shapes as shown in the sample figures I've also attached. However, similar facilities should have similar shapes. For example SPEC1 and SPEC2. If you could draw also a 3D sample showing that our facility hall is 4 floors, that would be great. There is a sample of a 3D facility attached. The PDF file is our project's specification. The Rectangular picture with black circles is only to let you have a sense where the beam tubes are coming out from. The remaining pictures are examples you could use where we selected the ones we liked. Be creative! Let me know if there is anything unclear. Best, Abdullah
