Re: Drive Geometry with "INSTANCE_SILL_HEIGHT_PARAM" in window and doo

Dear Jakob,

 

Thank you and congratulations for bringing your question out of our private email communication out here into the public forum.

 

Are you asking whether you can set the value of that parameter on a selected family instance after it has been inserted into the BIM project?

 

If so, the answer is yes, and it is one of the first and simplest tasks that is covered right at the beginning of the tutorial material pointed to by the instructions on getting started with the Revit API:

 

https://thebuildingcoder.typepad.com/blog/about-the-author.html#2

 

Here is a snippet of sample code showing how to retrieve an element from its element id, get the parameter associated with a built-in parameter enum such as INSTANCE_SILL_HEIGHT_PARAM, and set its value:

 

https://thebuildingcoder.typepad.com/blog/2019/06/accelerator-dash-pattern-fix-element-rotation-and-phase.html#5

 

There are many, many more samples where that one came from.

 

You might also want to check out a tutorial specifically on setting parameters in Revit. Here is the first one that happened to come up right now:

 

https://spiderinnet.typepad.com/blog/2011/04/parameter-of-revit-api-1-builtinparameter.html

 

By the way, here is another recent interesting question that is vaguely related to yours, althopugh a bit more specific and complex:

Cheers,

on the other hand, you can use .Name attribute with Revit FamilyInstance and Element.

i guess the attribute is not used for the same reason on ElementType, because if just for setting.

About set filter rules... (revit2018)

1.PNG2.PNG

 

Hello, I am a beginner of REVIT API.
Recently I have been writing a code that applies the filter rules in a short time.

Works well if only one filter rule is applied, such as the first capture.

However, the code for implementing a second capture, for example, does not work.

If a user-defined level exists, the user has created a code to add filter rules for it.

Is there a problem with my code?

thank you.

Sometimes  Use Rebar API SetHookOritentation methond is invalid

When using the Revit project of the structural template, there is no problem creating reinforcement.

 

When using the Revit project of the building template, the created rebar cannot change the hook direction (SetHookOrientation is invalid), There is another problem, the created rebar plus the hook will produce many rebar shape family types.  Did anyone else find out？

What should I do?

Revit API - C# - Sun and shadow setting - calculating sun direction

November 30, 2019, 12:45 am

Hi all,

I'm using the example code from Jeremy Tammik to calculate the sun directions for a year period through Revit API. https://thebuildingcoder.typepad.com/blog/2013/06/sun-direction-shadow-calculation-and-wizard-update.html

 

So I basically loop it in order to get the whole year 8760 hour's sun direction.

 

However, when I export the data to excel, the data seems not right. the vector for sun direction stays the same for many hours, which is not right. I double-checked the Activeframe time. It is correct. 

 

Below is my code (with visual studio version attached) and the attached image is part of my data, which shows the problem. Thank you!

catch 22 - generating floor from CurveChain

Hello,

I want to generate a floor from a subface of a room, mostly it works like a charme but I managed to get one situation where I have the following problem:

New Floor method throws the error that the provided curve is not a closed loop, and guess what this is true. (which is funny because I get the profile Curve from a face)

So i decided to simply close the Curve, but than trying to add the line to close the curve I get an error that the curve I am trying to add is to short.


So I can't generate a floor because there is a gap, but I can't close the gap because it is too small?

Unfortunately, this is not the best place to ask such a question.

 

Please note that this discussion forum is dedicated to programming Revit using the Revit API.

 

Therefore, you cannot expect an answer to a question such as yours relating to installation, product usage or end user support issues here.

 

You should try one of the non-API Revit product support discussion forums instead for that:

 

https://forums.autodesk.com/t5/revit-api-forum/this-forum-is-for-revit-api-programming-questions-not-for/td-p/5607765

 

The people there are much better equipped to answer your question than us programming nerds.

 

I hope this clarifies.

 

Thank you for your cooperation and understanding.

 

Best regards,

 

Jeremy

It is unclear what you are trying to achieve.

 

On one hand, you mention PipingSystemType.

 

On the other, MechanicalSystem, not MechanicalSystemType.

 

A system is different from a system type.

 

Please clarify exactly what you want to achieve for yourself, first of all, before discussing this any further.

 

I suggest you work through the end user interface first to build an appropriate sample model and analyse that, its elements, their properties, relationships and classes, e.g., using RevitLookup.
