CE - Fully Constrained Primitives are not Parametric?

So i can model and fully constrain 3D slabs and other primitives, but if i need to array those primitives the tools don't work because they aren't parametric solids.... but they are fully constrained in every dimension with variables which means they are parametric?

If i cut the primitive i can make it work but it adds an un-necessary operation is there another solution?

I could extrude a fully constrained 2D profile to make a slab but this is again more complicated then it needs to be...

Am i missing something?

  • I assume you have placed the Slab using Variables to control the Height / Width / Length in the Tool Settings thus constraining its size. The element Type remains as a Slab as can be seen in the Properties dialog.

    The normal Array tool (Drawing > Home > Manipulate > Array) can be used on this Slab although appreciate, you will not have the ability to use variables to control Row/Column spacing as with the Array Feature tool.

  • Correct i cannot use the variable controlled row/column spacing tools for a parametric part.  So i have to take a extra step of cutting the end off my slab (or extruding a 2D profile) to make it into a parametric solid so it can be arrayed with the parametric tools.

    I can't be the only person who finds this weird and silly taking what is others a fairly elegant means of parametric modeling constrained 3D solids and makes it more complicated for the sake of making it complicated.  I can constrain the slab in any way i just cannot array it.

    So can we get a toggle or something to turn primitive solids into parametric like so they can be arrayed?  ...or just un-lock the power to array primitives parametricly?

  • Which version of CONNECT are you in?

    In the array parametric feature tool there is a setting for "Whole Element" that you can enable, this was added in Update 4, see below:

    This should work on any solid when done you can review the array through the Properties dialog:
