Creating a pattern with conditions

Anonymous — Tue, 13 Feb 2018 06:57:26 GMT

Hi,

I'm trying to make a pattern with holes that will take into account the length of a steel beam.

The conditions are:

1. Number of holes are controlled by the lenght

2. Min. distance between the holes are 300mm (As soon as we can fit one more hole that gives us 300mm between the holes, inventor will add a hole)

3. The distance from the ends to the first and last holes are half the distance between the holes.

I guess I have to use the floor() command in parameters, but I'm kind of stuck there.

Anyone got an idea of how to do this that can push me in the right direction?

Hi Gringonor,

I am afraid that pattern can't make it. However, iCopy is a solution for you, try it out.

Thanks

Gringonor,

The enclosed part will update the number of holes when the length is changed. This is simply done by parameters, using floor() as the rounding function.

Hi! If you are on Inventor 2017 and later, you could use Sketch Driven Pattern. Basically, you need to create sketch points, spaced out according to the conditions. Then pattern the hole based on the sketch points.

Many thanks!

@Anonymous, this is possible as @torbjorn_heglum1 said.

As I'm not able to open and have a look at his part (I'm using 2016), I've added a picture that shows how you can set this up.

If you instead need to have maximum 300 between holes, simply replace "floor" with "ceil".
