rebar problem

Ramin-AZ — Tue, 19 Sep 2023 00:52:27 GMT

hello,

I have two shapes and the rebar in one of the shapes has a problem
My problem is that in figure A I want the distances to be fixed

Could you edit the Constrains of the rebar back to a point that wont change such as the Start Face or could be a reference line or similar

I placed the M06 Rebar Shape using Expand to Host then Edit the constraint for the Right Hand End to the RH slab Edge and changes to 0 and dragged the Handles for the Sloped element

Then in Plan used Varying Set

Is this what you were after?

hi @jay_colc

You may show this in this file
I could not fix it

Ouch this is a pain, i cannot see in Revit with this shape any other way apart from creating one and arraying it and believe my i have tried.

The only alternative is the common used hack and draw the reinforcement as a square and use a something to cut the angled slab shape out but i struggling to find a way to do this.

I know there some third party adding out there which could probably get around this but at a cost!!

@jay_colc

I made a parametric slab that changes length and angle
There is a method in this video I am looking for another way Because it doesn't work for me

You are correct that wont work, the issue here is that the step down in the rebar shape does not adjust with the edges so whenever pinch the slab inwards it will always be uneven to the edges, stretching out will always work as it is still central to the increased area.

Hi @Ramin-AZ

The only way you could do this is by using free form rebar and an additional geometry element.

Steps:

Create a model in place element whose faces can be used to define the reinforcement. You can use blend for this. Make sure to use a category that can host rebar or check the "can host rebar" box in the properties for generic model

Place aligned distribution and select the 3 top faces plus a side face as the distribution path

Choose Workshop Instructions > Bend (this matches the bar geometry to a rebar shape and reports A, B, C)

Add 90 deg hook at start and end

Rotate one of the hooks 180 deg, to match shape M_06 (for this example it was hook at end)

After this you can adjust the model in place and the rebar will follow

Hide the model in place in all views where you don't need to see it

hi @ovidiu_paunescu

Thanks for your trick

This way of yours makes me do an extra job
If I have this type of rebar in many places, the software becomes heavy when working
My file size is also increasing
So shouldn't this REVIT be more intelligent to be able to do this simple task?
