Param-O display is not acting consistent.

It may be my programing, so I am posting screen shots. I am creating parallel bars that maintain a chosen width and spacing that allow the group of bars to stretch and change in number as needed. The Param-O 3D display shows the bars with proper size and spacing. However, the same parameters are use when placed as an object. But the bars are wide with no spaces between. Also the object dimensions are longer in the Y-axis, which should not be. It behaves properly in Param-O, but not as an object. Why?

It should work. I've made similar objects without facing such an issue.

Have you tried fiddling with the parameters after placing the object?

I hope I have the correct understanding of your terms. I believe you want your bar length (e.g., 8’ long members) connected to your Block Size Y and your bar span (e.g. 20’ run of bars) feeding your Transformation logic sequence. Your bar width (e.g., 1.5”) would connect to your Block Size X.

This should provide equal spaces between the members based on your bar count within the span/run. You might also consider use of the Line Points node in lieu of the ND node; not sure if there is an advantage, but I’ve had success with Line Points.

I have tried multiple parameter changes

Here is the Param-O object.

I experimented with replacing a Number Distribution with a Number Series and get the same results.

(After some sleep) I just discovered what the problem is. For the Bar Width, it was reading a Metric value, because its input value was a "Number" rather than "Length" After making the change, it works fine.

I tried to reproduce the PARAM-O object and it failed me when I connected here

I also observed several times where the 3d views and 2d views did not match up as expected.
