I’m trying to make a tapered mass where I can stack them on top of each other and the bottom of one would take the size of the one its sitting on. I remember seeing a tutorial years ago, but I can’t seem to remember how to do it

I’m making a pretty tall light tower with cross bracing and i thought this would be the quickest way. Any help would be greatly appreciated

thanks

Why wouldn;t you make a single tapered mass the entire height, and if you need intermediate areas, use floors/levels?

i guess i could, but i remember seeing that tutorial and i thought it would be a good idea to learn how to do it make the bottom of one mass match top of another if they are different sizes.

Just a question.  How are the corner columns going to work if they are not continuous and how will that affect the x-bracing?  Columns don't work very well if not supported.

i wasnt going to use columns since the original wasnt built using columns..  it looks like it was built using all steel angles and angle cross bracing. Attached is what i came up with but i wasnt able to get my family to automatically adjust to the size of the mas below it.  i attached an image of the parameters. if anyone knows how i can fix it so i dont have to manually adjust it, that would be awesome. i attached the family as well in case some can figure it out

 

thanks!

The tapered cangle columns work in the tapered tower.  Your tower will be straight and the structure will not work.

i may be missing something, but i dont understand what your trying to say

i just to make a parametric family that will taper according to the mass below it.  i want to use it to make sweeps not actual steel columns because im replicating an actual existing tower which is using all steel angles.

 

but i dont know the exact size of this tower so if it changes, id like to be able to make a quick change using this family

 

i know its possible, i saw it years ago and i cant remeber how to do it or where i saw the tutorial

jsel13,  I am still not convinced you are approaching this the right way, but of course I don't know all the details of your project.  In the interest of learning, If I had to do what you are talking about, I would create a family with a whole lot of parameters, Such as:

 

Mass1 Bottom Width

Mass1 Bottom Depth

Mass1 Top Width

Mass1 Top Depth

Mass1 Bottom Height

Mass 1 Top Height

 

That would create the first mass.

Then you make a second mass and make similar parameters, but some would have a formula attached:

 

Mass2 Bottom Width = Mass1 Top Width

Mass2 Bottom Depth = Mass1 Top Depth

Etc.

 

The question is how many boxes are you going to build, and it could get to be a very long and cumbersome creation.

there are 18 of them

i saw a tutorial once where someone built a tapered box, then arrayed it up so the boxes sat on top of each other and they conformed to the one below it. it was like 2 to 3 years ago and i cant find it online anywhere. i saved it when i saw it, but i switched jobs recently and i must not of copied it.

 

 i think it was a mass family which was brought into a project, then it was arrayed and rotated, but the bottom of one equaled the top of the other and there were like 30 of them in the example im talking about

This seems like a lot of work.  I'm with LIZARD, why not just make it a single mass tapered mass?  Might be good to know how to do what you are looking for in some case that I can't think of but like I said seems like a lot of extra work.

jsel...in the example you are talking about, what was the person trying to create?

i think they were just creating a mass for a building showing how you can align the bottom of one mass family with the top of the one below it and rotate it up to creat a building that was tapered and rotated

kind of like what im trying to do here without the rotating

 

i know there are easier ways to do what im trying to do here specifically. but as teafoe said, it would good to know how to do this.
