    Creating Base Plate Family

    Hello all,

    So I've searched this question out before I posted and if I didn't see it already answered, my apologies in advance.

    I need to create a base plate that will have the following features:

    1. I need to have a length, width, and plate thickness parameter. Obviously the easiest of all my needs.
    2. I need be able to have a parameter for number of holes and their center distances on the plate.

    Comment: Normally we only deal with 4 hole base plates, but we do run into projects where we have base plates with fixed end moments that require 6, 8, or in our case recently, 12 holes.

    3. I need to be able to have a edge distance parameter to the hole center lines in the x & y directions on the plate
    4. I need to be able to schedule these plates and have them tag appropriately in plan view.

    The two features that stump me in this creation are:

    * The specification of number of holes and have it generate them in the plate and the scheduling aspect of the base plates.

    * Getting them to auto generate mark numbers and schedule accordingly. In the past, I have manually input a Mark ID on the plate and then created a custom schedule that will schedule the marks, but that seems very labor intensive. If anyone has any insight on how to streamline this process, or if such a family is already created, I would be forever grateful.

    Thanks for your help.

    Have you tried starting with one of the OOTB base plate families? They can be located in the Structural Connections > Steel directory. I've attached an example of one of the families. This might be a good starting point.

    Tony,

    Thanks for the response.

    Yes, I have. In fact, I modified that base plate family for the previous project I worked on, but it required a lot of tinkering to get the base plate I wanted in the model. It was then that I thought that I would create the custom family myself to make the process more streamlined.

    I would avoid trying to model the holes. Instead I'd either show the bolts, or model line circles where the holes would be... or both.

    I also wouldn't try to get them to auto mark. You could use Dynamo to concatenate several parameters to use as your mark if you've got a lot of variation in types. From my experience there are only a handful of base plate types so it's not much work to manually enter them... but your experience may differ.

    The rest should be pretty straight forward in terms of layout, parameters, etc.

    Have you tried nesting the 6 bolt, 8 bolt, and 12 bolt patterns into the base plate family. and then using viz setting to control witch you would want?

    Darius,

    Great idea. I've gotten tied up with stuff at work over the last few days, but I will try that. I was also given the advice to make it with a parametric array and having the array void the geometry as it arrays.

    I'll try both & report back.

    Thanks.
