Frame 27

Frame 27

You will switch to frame view "Frame 27" to modify the floor between the hull and the lower deck "Deck 3500". You will make the following modifications to this floor:

  • Change the position of all holes from 3000 into 2800 mm above base;
  • Change the type and size of the outmost hole from type "manhole" with diameter 450 mm into type "creep hole" with height 600 mm and breadth 450 mm;
  • Change the upper right corner radius from 75 to 100 mm;
  • Add three welding holes with radius 35 mm around the seams in the hull;
  • Change the radius of the inner welding hole from 35 to 75 mm.

When you have completed these modifications, you will copy the floor to frame 28 and frame 30. Please remind that welding holes are not topological and therefore the best procedure is to copy the floor first and then create the welding holes.

  1. Open drawing frame view "108-27"
  2. Choose Update active block
  3. Place standard text "Frame 27" above view using current control
  4. Change position of all holes from 3000 to 2800 mm above base
