I require basic AUTOCADD modelling. Can be done in few hours.

Channel Dimensions:

Length x-direction: 21.3m

Width y-direction: 0.66m

Height z-direction: 0.7m

*all these include a 0.1m buffer (the red areas) which is the wall of the channel.

The blue area at the side is the side weir, which is basically an opening.

0.6m

0.1m

0.46m

Model A:

1 Side weir is located right in the middle of the channel (x-direction) and at the top of the channel wall.

1: 1 Side weir of 2.3m x 0.2m starting from 9.5m from the ends (x-direction) and 0.5m from the bottom (y-direction).

2: 1 Side weir of 2.3m x 0.15m 0.55m from bottom.

This “space” is the side weir.

3: 1 Side weir of 2.3m x 0.175m 0.525m from bottom.

4: 1 Side weir of 2.3m x 0.225m 0.475m from bottom.

5: 1 Side weir of 2.15m x 0.2m 9.575m from the sides.

6: 1 Side weir of 2.0m x 0.2m 9.65m from the sides.

7: 1 Side weir of 2.45m x 0.2m 9.425m from the sides.

Total = 7 models of model A.

Side view (y-direction)

Model B:

1 Submerged side weir located right at the

Base of the channel wall.

0.1m

1. 2.3m x 0.15m starting from 0.1m from the bottom. (0.1m is the bottom wall of the channel)

2. 2.3m x 0.175m.

3. 2.3m x 0.225m.

Total = 3 models of model B.

Model C:

1 submerged side weir located in

the middle of the channel wall.

1. 2.3m x 0.15m located right in the middle of the channel wall (i.e 0.225m from the bottom base and 0.225m from the top of the wall.)

2. 2.3m x 0.175m (0.2125m from top and bottom)

3. 2.3m x 0.225m (0.1875m from top and bottom)

Total = 3 models of model C.

Model D:

2 equal side weirs located right in the middle of the channel but on opposite sides of each other. (1 side weir on each wall facing each other).

· Similar to Model A, but 2 of it and of 50% size.

1. 1.15m x 0.15m each, located 10.075m from the ends of the channel.

2. 1.15m x 0.175m.

3. 1.15m x 0.225m.

Total = 3 models of model D

Model E:

2 equal side weirs located on the same wall of the channel.

· Similar to model A, but 2 of it and 50% size.

9.875m from start of weir to end of channel.

Dsgd

1. 1.15m x 0.15m each with 0.4m spacing. Located 9.875m from each end of the channel.

2. 1.15m x 0.175m.

3. 1.15m x 0.225m.

Total = 3 models of model E

CONCLUSION

I require a total of 19 models. As these 19 are just minor dimension tweaks to a basic 5 models which are also essentially evolution of a basic model, it should be quite easy to model them after completing the first model.

I also require all this to be sent to me in .stl format.

I have attached basic models of models B, C and D also in .stl format for reference which will surely hasten your completion speed.
