Sweep not permitted in a FamilyDOcument

dirk.neethling — Fri, 24 Mar 2017 08:53:16 GMT

I am trying to create a FamilyDocument, which should contain a combination of swept profiles, depending on Input.

I am using an existing FamilyDocument (*.rfa) as template.

I have successfully tested the code for sweeping in the FamilyDocument, however when I remove some unwanted, unrelated passive Families from that document, I can no longer create the sweep.

So my quetion is: what conditions are necessary for me to be able to create a sweep?

Regards, Dirk

OK, so I selected the following template:

C:\ProgramData\Autodesk\RVT 2016\Family Templates\German\M_Profil (Sweep).rft

Now I get this:

exc = {"Sketch plane creation is not allowed in this family.\r\nParameter name: document"}

Really frustrating. Which template do I need to use in order to be able to construct a sweep?

Hi,

I think the template you mentioned is a 2D template, just for creating 2D profile families.

What about using "M_Allgemeines Modell.rft" for your 3D sweep ?

Yes, I tried "M_Skelettbau" and managed to create the sweep.

When I instantiate that Family using ist Symbol, I get this:

+ exc {"The symbol is not active.\r\nParameter name: symbol"} System.Exception {Autodesk.Revit.Exceptions.ArgumentException}

Hi,

before using a FamilySymbol fs, you need to activate it:

if (!fs.IsActive)
{
fs.Activate();
}

the Profil templates are basically a plane for a profile-loop

Use M_Allgemeines Modell.rft instead.

Hello Revitalizer,

I have this question:

I managed to create the FamilyDocument, to load it, and to instantiate it.

THen I try to apply the same transformations to it, as the ones for the segmental tunnel elements. THese include flipping upright, turning around the central axis and translating.

It seems that all Rotation transformations are not possible.

I get the following Errors. What Features do I Need to give the Family so that it can be transfomrmed after being instantiated?

Hi Dirk,

I think this is caused by the restrictions of your family.

Depending on family category, there may be a boolean "Immer vertikal" respectively "Always vertical" property in the family editor.

This will prevent rotations around all but the Z axis.

You also could try to use a line-based family for your edges.

OK, I found the check which stipulates that the element should always be vertical.

some additional questions:

- How can I programatically uncheck that?

- how can I convert this Family into an adaptive element?

- when I try and Close the FamilyDocument, after creation, the code cracks. How can I sequentially generate the FamilyDocument based on Inputs, then Close it, and then call it in a Project document?

I tried using "M_Allgemeines Modell (Linie)" as a template. Now there is a new issue. I get a Dimension which I have to somehow edit, not understanding what the thing wants from me.

Very frustrating working with FamilyDocuments, which is why I intuitively tried to avaoid them.

Which template will allow me to generate a 3D model and transform it freely?

Hi,

- How can I programatically uncheck that?

That's a parameter of the Family.

- how can I convert this Family into an adaptive element?

Use a family template for adaptive components

- when I try and Close the FamilyDocument, after creation, the code cracks. How can I sequentially generate the FamilyDocument based on Inputs, then Close it, and then call it in a Project document?

I think it's a question of transactions.

LoadFamily needs to be performed outside a transaction.

Close the family document after loading it into the project file.

Have a nice weekend,

Can die "AlwaysVertical" Parameter be modified after instantiation of the Family?

Hi,

I don't know, just test it 🙂

Hi,

the parameter is part of the family, not the element or the elementtype.

You mean accessible through the Symbol obtained from

profileSymbol = Util.FindFamilySymbol(.. ?

Hi,

yes, the FamilyInstance.Symbol.Family.

the crazy Thing is that I manually Switch off the flag AlwaysVertial in the FamilyEditor, save it, and then when I instantiate the Family, it's active again!

Re: Sweep not permitted in a FamilyDOcument

Hello Revitalizer,

could you pls help me with the creation of the Family? I've tried out al the Generic classes,

M_Allgemeines Modell...rft

None of them enable me to create an instance which I can flip upright.

Which template should I use to create an instance which I can then transform w.r.t. all degrees of freedom (rotate about the 3 axes, translate in the 3 axes)?
