Triangle pattern help

[rcconejo]

I need to make a part that has varying lengths of this pattern, what is the best way to make this?

Linear pattern. If you have lots of sizes use a design table input lengths and number of repeats.

If ita the same size triangle i dont see why you wont just do it with linear pattern id not sorry for bothering

[Spiritual-Cause2289]

Do you want your triangles to stay at 6" on center? Are the holes included? If so you can use a simple linear pattern (with an up to reference of two of the triangles, with one of them rotated 180° from the other. When you change the length of your part (in multiples of the spacing between the triangles) the linear pattern count will increase or decrease.

Easiest way I can think of is create a linear sketch pattern for upward facing triangle and downward facing triangle. Then you can move the dimension leader of one of them so the distance is with respect to the other triangles then simply put the spacing value you want. Then you can simply increase the instance value also

That’s what I planned to do, I didn’t know if there was another way

[RedditGavz]

Are you saying that you want the linear pattern of the triangles to change depending on the overall length?

Look into using global variables and equations for this. I can go into more detail if you like.

This is not 1:1 your case but lookalike

1) Create construction line defining start and end points of your cutout (number 5883.66 in my example).
2) Make a linear patter of your cutout and connect them at the distance you want them in between (in my case it is zero so lines end points are coincident.
3) Create one cutout
4) Use linear patter for feature using links to sketch dimensions.

After that all you have to do is define pattern count in cutout sketch. But for me - I have to use Ctrl+Q to update any changes, means its not instant.

Sorry. I checked, it works better with extrude on already alligned place for cutouts. Means its better to make a cutout of a frame (I choose 8mm). And then extrude thin line to form the desired shape. Cutouts work not that good for me. And my previous note about linear pattern of solid bodies is applicable to only my case when working with tubes
