# Tutorial on how to model a rope.

This is the part that will be modeled now. Rope 6X12/6/1 configuration.

1. ### Step 1:

1. Open a new part and select front plane to sketch. Sketch the profile from the origin as shown.
Dia 5.80mmX12circles,
Dia 5.90mmX6circles,
Dia 6.49mmX1circle.
I have renamed the sketch as "Main profile" for my convinience.

2. ### Step 2:

2. Next, select right plane and sketch a line from the origin. This is the "Main path".

3. ### Step 3:

3. Now use the SWEEP feature to sweep the core.
Select the sketch1 (main profile) as the profile and sketch2 (main path) as the path.

4. ### Step 4:

4. In property manager, select TWIST ALONG PATH defined by DEGREES and spcify 1080degrees (or 3turns). Accept.

5. ### Step 5:

5. The part would look like this.

6.

7. ### Step 7:

7. Select front plane to sketch. Sketch the profile as shown. Remember the "Main profile" sketch? Coincide its centre on the

Dia 60.01mm circle. (I call this as Strand profile) I have hidden this sketch for time being.

8. ### Step 8:

8. Next, Draw a circle of Dia 60.01mm on the front plane starting from the origin. We'll use it to generate a

9. ### Step 9:

9. Select Helix and Spiral from the curves dropdown in features tab. Select the dia 60.01mm circle you drawn. Spiral is defined

by Height and Revolution. Height = 900mm and revolution = 1.5. STARTING ANGLE is 180 deg.

10. ### Step 10:

10. Use sweep feature to make the strand. select the sketch3 (strand profile) as profile and the helix as the path.
Use Twist along path defined by 1080deg (or 3turns).

11. ### Step 11:

11. The part looks like this.

12. ### Step 12:

12. Create an axis at the intersection of Right and Top planes.

13. ### Step 13:

13. Select Circular pattern from feature tab. Use the axis you created to pattern around.
Under bodies to pattern, select all the solid bodies from the "SWEEP2" feature. No. of instances=6 with equal spacing.

14. ### Step 14:

14. This is the finished part.

15. ### Step 15:

Now you may render it with you favorite rendering software.
