Chamfer around Precast panel

Shaiki_ — Fri, 09 Mar 2018 02:30:34 GMT

Hello,

What would be the easiest way to create a chamfer around the perimeter of a precast wall panel as shown in the attachment? For this I modeled in place a void sweep, but this wouldn't be ideal for doing on 100s of panels. I like how the void sweep adjusts when the panel dimensions adjust though, so hopefully there is a solution that allows for that! (I'm looking at you, reveals.)

your method is very good.

However, this can be done also by the tool wall/reveal.

Reveals are only a solution if there is a way to constrain them to panel edges. Otherwise I constantly need to be adjusting them, and they're hard enough to deal with as is!

How did you create the precast panels to start with?

Just a wall that we turn into parts and split with parts-divide. If its a solid wall as shown in the example I can use a division profile to create the vertical chamfer, but I haven't figured out yet how to use a division profile on a wall with multiple layers as is the case with insulated panels.

The top and bottom horizontal chamfers can be dealt with by modifying the section profile of the wall family. Its just the verticals on insulated panels I have yet to figure out!

You can create a grid of named reference planes (or sub-levels + sub-grids because they are auto-named), then lock the reveals to them. Divide parts using Intersecting and choose the above grid. When you move a reference plane the reveal will move and parts will size accordingly.

2018 test file attached.

Awesome, I love the intersecting sub-grid idea! How do I lock reveals to anything? I tried by alignment but when move the grid the reveal stays behind and I get a 'Constraints not satisfied' error. Also, If i want to split the parts with a 1/2" gap, will the reveal method still work? It appears that to get the chamfer in each panel here, you're splitting the reveal as well.

In the test file it looks like you arrayed the reveals thus creating groups...does this have anything to do with the process or would it work putting in reveals one by one as well?

I create the reveal profile as a triangle so that I can (tab) lock the center line to the reference plane on an elevation. If your reveal profile has no center line you can lock it to a reference plane by EQ/EQ the edges.

The reveal were arrayed but it is not necessary, you can copy them or place one by one.

ji @MostafaElashmawy is there a way to automate this ?
