repeat an object on curved path 3

[mahmoudxp]

Hello
How can I repeat an object such as pocket(gear form) on curved path in CATIA?

Thank you

check knowledge template in the online doc. You will need special license for that.

or a macro, i think.

hi,

Try circular pattern by specifying the correct normal axis or you can try "user pattern" by creating points on the circular path. All the best.

1. Powercopies basic style. No extra license needed but you might end up creating lots of construction geometry based upon the complexity of the desired output feature.

2. Powercopies with Knowledge Patterns and UDFs You need PKT/KWA licenses for creating KPs, Rules, UDFs. just as itsmyjob mentioned earlier. However, almost all of your construction geometry can be made in the memory.

3. Automation using VB or VBA macros, etc..

hi
Is there a way without writing macros? I want to make gears on the path shown.

Thank You

hi,

Try user pattern by making points along the curve and patterning the required feature. All the best.

How was the path made?
What feature represents it on the Specification tree?

There are a couple methods you could do manually to get the gear teeth to follow a 3D curve. The steps are: 1. make a straight pattern of the teeth, and 2. wrap the flat pattern onto a curved surface (using Sheetmetal or Developed Shapes). You could also try making a Law from the flat pattern and then use the Law for a parallel curve.

could you attach a picture showing what you're trying to get.

 

[mahmoudxp]

hi, with user pattern and many points("geometrical set") I couldn't make pattern.
thank you

 

[sudhakarn]

Hi,

You should define all the points as a one single sketch for the user pattern. you can make this by defining by creating "equidistant points" in the sketcher workbench. Hope it helps. All the best.

Mawmoudxp,

Thanks for the picture. But which direction do you want the teeth to be positioned?

See my attachment. Are the teeth parallel to the ribbon like a saw blade (red in my attachment), or perpendicular to the ribbon like a timing belt (blue in my attachment).

Do you have a picture that shows the final design?

 

[sudhakarn]

Hi,
you will have to use the anchor point option in the user pattern to position and align the feature accordingly.

the red lines you've drawn is correct but I need to make gear teeth on these red lines(like a saw blade). The pattern is related to banister of a building.

Thanks

A banister, like shown below. To duplicate the pattern of the rails, I think a PowerCopy would be the best solution, as was previously mentioned.
