This week I continued working on the xml generating code and now all the methods, constructors and enums are translated to the format used in the api files. There were some extra packages needed to run aside from the ones specified on the website ... [More] (will update the information there when I finish generating the wrappers, to make sure everything is ok).

The run time was not affected by the newly added packages.There are 177 packages used by the old OccWrappers.api and 205 packages we need to parse in order to export the xml files for these. I wrote a LinqPAD program to check that all the required packages were exported and another program to concatenate the classes into one file for each package. The next step is loading these partial files in the NaroHost solution and checking that the translation was done correctly. Aside from loading the xml files, it will transform the C++ types to the types used in C# and do the Setter/Getter transformation. After the check is finished, I will incorporate the test programs in the NaroHost solutions so that the checks and file merges are done automatically. [Less]

Here is the first version of the xml code I got from updating the cdl parser in OcWrappers (.api file on the left, generated code on the right):The code was generated using .edl templates and the same code that is currently used to generate the .cpp ... [More] and .h files, which means that changes are easy to make, propagate automatically to all classes and the new files can be obtained quickly. I've run the parser for all the packages, all classes and all methods in OpenCascade 6.3.0 and the files were generated in 1 minute and 30 seconds.Next week I'll change the templates for constructors, destructors and properties and 'translate' the parameter types to the types used in C#. After these are done, I will check to make sure that the templates are correct for all classes used in Naro. [Less]

Over the past week I worked on updating the wrapper generator that used to generate the OCWrappers.dll. In the current workflow the OpenCascade 6.3.0 files are parsed, generating full .h and .cpp files which are then compiled in the dll. This dll is ... [More] used as a base for the NaroOccCore solution which generates an .api file used to load the needed classes and methods from the dll, extracts them and generates new .cpp and .cs files.I'm working on improving the OCWrappers code so that the Open Cascade files are parsed and the .api file is generated directly from them, without having to compile the .dll and then use reflection to extract the information we need.

Good news for the NaroCAD project users: we decided to allocate 4 weeks of development for wrapper work starting from today.Beside enhancing the wrappers structure we'll work also at updating them to the latest OpenCascade version and improve the ... [More] wrapper generator tools. By bringing the latest OpenCascade fixes into the project we plan to have many modelling issues fixed.Another cool surprise will be announced soon... [Less]

Today we released NaroCAD 1.7.6 Beta:- Added the Three Points Rectangle - Added the Perpendicular line Hinter and improved the existing Hinters- Added coordinate increments for drawing and editing sketch shapes- Fixed Copy/Paste for Boolean solids- ... [More] Fixed the Rotate Axis Tool for sketch shapes, solids and 3D shapes- Fixed the Property Grid Translate- Improved the Mirror Line, Mirror Point, Array Pattern and Circular Pattern tools- Improved the Line tool to display the length during drawing- Fixed the Measure Tool- Improved TreeData, NaroSketchSolve and Action TestsYou can download it here [Less]

Today and yesterday I worked on improving the tests projects and cleaning up the code:- removed the unused MetaAction classes and related tests- updated the test methods that create regular shapes using clicks- fixed the MetaAction tests (Sphere ... [More] , Cone, Torus, Cylinder)- reorganized the tests and fixed their names - fixed a bug for the Three Point Rectangle- replaced the setup code for the NaroSketchSolve tests - this allows us to correctly configure the ActionGraph and Document and run the Solver- fixed a path bug that caused the NaroSketchSolve tests to crash- removed some test methods that were duplicating existing testsThere are still some tests that need to be fixed, in the TreeData project, and we need to write more tests, as the tests we have now cover the creation of nodes and only a few of the possible cases.The Tests projects status is:Tomorrow I will fix a Hinter bug that is causing the Perpendicular hinter line to be wrongly displayed when working with 3D objects and continue fixing the tests. [Less]

Today I added the Three Points Rectangle, which gives us more flexibility when drawing rectangles, as its sides don't have to be parallel to the axes. Here is a demonstration where three rectangles are drawn on the side of an extrude:I also fixed the ... [More] Measure tool and since it is applied only on Sketch shapes, I've moved it under the Dimension tool:As you can see, the Dimension tool is used for lines, when we want the length to remain displayed, and the measure tool when we want to check the distance between any two points on the scene. I also updated the tests, fixed some of them and added new methods for the Mirror Point and Mirror Line tests. There are 79 TreeDataTest, with 8 failures and 2 ignored tests: [Less]

Today I modified the unused OrthogonalLineMatch so that we'd have Perpendicular hinter lines along with the other ones. These hints are displayed correctly for the default plane for now, because of the way the NodeHelper loads axes for processing:You can find the changes here
