Greetings

Can an equation be used to calculate equal distances when using the rectangular pattern.Regarding the attached .ipt file i would like to place 25 holes in the X direction with equal gap size between each hole.Also how to calculate the number of holes in the Y direction again with equal distance between each hole.I have not done this before with equations but was thinking that i would need to use the Length x Width in the equation.Do i need to add figures into the Parameters box also?

The attaced file with the Hole feature the sketch is not constrained for the purpose of using an equation so i know how far from the start of the part to get equal distances between each hole to the end of the part .

Any help with the equation would be great

try this, I put some dimensions on your hole sketch

Hi Stephen

That was very helpful.Thanking you.

I played around with your example and all makes sense except for dimension D13 & D14 which was divided by 2.Could you please explain the purpose of D13 & D14 being divided by 2ul

Best Regards

Could someone please explain why dimension D13 & D14 are divided by 2ul

Best Regards

To get the same offset dimension in other side of plate

if you put only d0 / xholes note the last hole coincides with the plate edge, so ( d0 / xholes ) / 2 ul

fantastic...Thanks Stephen and Maria
