External Command Initialization issue

≪ Previous: Re: Importing an excel sheet using c#

I have completed the Revit API tutorials and written a number of example classes with general success.

However I am having a strange issue that I cannot seem to resolve.

I created a code snippet of the External Command instantiation rather than type all that into each class. But when I use the snippet VS is erroring out on the IExternalcommand.Execute statement. Now if I type that into a new class it works fine but copy/paste or Snippet generates an error and the class will not debug or build properly. Delete the text and type it verbatim it works.

The error is

"Must declare a body because its not marked abstract, extern or partial"

Here is how I am declaring it:

[TransactionAttribute(TransactionMode.Manual)]

    public class DeleteElement : IExternalCommand
    {
        Result IExternalCommand.Execute(ExternalCommandData commandData, ref string message, ElementSet elements)

Again this works fine when I type it even using suggestion to fill in, but past or snippet does not work.

The model line (and in fact all database elements) has a property named Location:

https://apidocs.co/apps/revit/2019/89438f4f-7e15-835a-0c66-d6adbc8dd00c.htm

You can cast the value returned by it to a LocationCurve object:

https://apidocs.co/apps/revit/2019/9dd6eb99-f105-a05f-dc1b-dfde17b8768c.htm

For a straight model line, the curve is in fact a line segment.

You can obtain the line endpoints from that.

You can also modify the model line by setting its Location property to a new LocationCurve object with a different defining geometry curve.

Dear Chubbard,

Thank you for your query and congratulations on your success so far.

Looking at your code snippet above, I see a function signature with no body.

Therefore, the error message 'must declare a body' makes perfect sense.

I don't quite see what you are trying to achieve.

If you like, take a look at The Building Coder samples:

https://github.com/jeremytammik/the_building_coder_samples

They define a large number of external commands and simply repeat the declaration of the Execute method signature for each.

Jeremy

I didn't post the entire class, just the signature. In my snippet I have the signature and closing braces defined, I then insert the body code.

Now if I type the function signature my class builds and runs fine. If I use the exact same code via cut paste or snippet it will not build or run and the error is below. I cannot figure out why it makes any difference how the text gets added to the class.

What I am trying to accomplish is to be able to create a new class quickly. I have snippets of all sorts of code stored on my system, I have never run into this issue where typing vs insert makes a difference.

Uh! This has actually been missed in the copy paste process. I tried to clean and simplify my copied code and apparently I messed it up. My apologies. I assure you the original version that I run has got t.Start() and t.Commit() within the same scope.

I found this in the remarks of SetSubSchemaGUID method:

"Fields of type Entity - subentities - need to specify their Schema. The framework will prevent subentities with incorrect schemas from being stored in the entity. Additionally, the access level of the subschema will be checked against the currently executing add-in and access to restricted subentities will be prevented."

I'm creating my sub-entities with a new Guid (or do I have to pass the main schema to the constructor?) and testing my add-in with Add-in Manager tool. Could this be part of the problem?

Here's how I created my schema:

                Guid schemaGuid = new Guid("A10D426E-5899-45E6-979C-BAE987B564B5");
                //Guid schemaGuid = Guid.NewGuid();

                SchemaBuilder schemaBuilder = new SchemaBuilder(schemaGuid);

                // set read access
                //schemaBuilder.SetReadAccessLevel(AccessLevel.Public);

                // set write access

                // set schema name

                // set documentation
                //schemaBuilder.SetDocumentation("Schema to hold construction schedule data items.");

                var mapField = schemaBuilder.AddMapField("MapField", typeof(string), typeof(Entity));

                mapField.SetSubSchemaGUID(new Guid("90BA988E-BE74-46BE-A2E4-1F23367621CA"));

                mapField.SetDocumentation("Each item in this map is corresponding to one CSDataItem. The int will be ElementId of the element & the Entity will store the rest of data.");

                // register the schema
                schema = schemaBuilder.Finish();

Update: creating sub-entities with a newly created "sub-schema" fixed the problem (instead of passing a new Guid). So not sure how the example above has been working in the past. It didn't work in my case. I had to create simple fields for my sub-schema. Here's the code:

            Guid subschemaGuid = new Guid("90BA988E-BE74-46BE-A2E4-1F23367621CA");

            SchemaBuilder subSchemaBuilder = new SchemaBuilder(subschemaGuid);

            // set schema name
            subSchemaBuilder.SetSchemaName("CSDataSubSchema");

            // create a fields to store CS values of  ElementTag, ElementName, ElementID, Category, Website, ProjectId
            subSchemaBuilder.AddSimpleField("ElementTag", typeof(String));
            subSchemaBuilder.AddSimpleField("ElementName", typeof(String));
            subSchemaBuilder.AddSimpleField("ElementId", typeof(String));
            subSchemaBuilder.AddSimpleField("Category", typeof(String));
            subSchemaBuilder.AddSimpleField("Section", typeof(String));
            subSchemaBuilder.AddSimpleField("Website", typeof(String));
            subSchemaBuilder.AddSimpleField("ProjectId", typeof(String));

            subSchemaBuilder.AddSimpleField("BindDate", typeof(String)); // date which the element got bound to this CSDataItem
            subSchemaBuilder.AddSimpleField("BoundToElementUniqueId", typeof(String)); // the UniqueId of the element which is bound to that CSDataItem
            subSchemaBuilder.AddSimpleField("BoundBy", typeof(String));

CustomExport, how to speed up Export Time?

≪ Previous: Re: Creating new Entity stops the external event handler

How can one successfully implement multithreading into CustomExporter / IExportContext?

Is there really no way to implement concurrency?

Have tried multithreading using window's TAP data flow, introducing queues and concurrent dictionaries as well to store a memory buffer of vital node information. However, the export time barely experiences any / much boosts in efficiency.

Am wondering if anyone has played around with the customexporter handling huge models, or know some one / link who might.

Is it really impossible to implement multi threading to facilitate export process?

Or could there be a better way that I have yet to explore in order to speedup the export process?

Congratulations on solving this.

Why do you need a subschema at all? Do you have a complex collection of schemata?

All other samples I have seen just use the one single main schema, no subschemata at all.

The Revit API and all the functionality it provides cannot make use of multithreading:

If you wish to use multithreading to speed up the custom export, the only possibility to do so is by using it in pieces of your code that are completely independent of Revit.

For instance, you could use your Revit add-in and the Revit API to retrieve the custom exported information, and then pass it on for further complex processing into other threads.

I hope this helps.

Yes the data structure is a bit complex. So I thought firstly storing one DataStorage element in the document and populating the data inside it using one complex schema would be much neater as opposed to creating multiple DataStorages for each "DataItem" that I have. Secondly using a map field of type IDictionary<string, Entity> suddenly makes all the IDictionary methods available to me to retrieve & manipulate the data, and also makes it easier to check for existing "DataItems".
