Hi. I’m trying to make a parameterized rebar in blender to show forces and utilization rate within concrete construction.
Very new to Blender and can’t find any good guids on how to do it. Looking for tips and tricks to do this.
I only need one (and I need to be able to make it longer and thicker with a python script.)
Any ideas on how to do it? or what I should start with?
The biggest problem is that it’s size(radius and length) has to be relative, or based on values from file. So I guess a parametric rebar is what i’m looking for. An object that can be used many times, with different values, and i don’t know how to do this with the ridges on the rebar.
You can model just a small part and then use an array modifier to make it longer. You can set keyframes in the array modifier to use it in an animation.
In this pic, you can see what I actually modeled on the right, and the use of the array modifier on the left.
In the blend file, if you scroll through the animation, youll see the rebar get longer.
you can easily scale the object to fit your needs.
It was a simple circle with 8 verts, then I extruded 2 on each side straight out. Then I added 2 loop cuts and angled them and then extruded that face out. Took about 5 minutes to do.
By setting the diminsions in the panel, you can determine the size rebar. z value woul be half of the x and y value. The one circled would represent a #5 rebar. You would do the size with the array turned off.
I think you dont need to get too hung up on precision. As long as you are pretty close, I dont think anyone will notice.
