dxf | DXF parser for node/browser | Frontend Framework library

I'm doing maintenance on a GUI, made in C#, using Visual Studio (xaml technology).
There are several visual components I don't see in the design view, like the Telerik and DXF visual components. I have no idea if this is due to a general problems ("Visual Studio Design view has problems external visual components") or if this is a specific problem for the visual components' libraries ("Telerik is not viewable in Visual Studio's Design view" or "In order to see DXF visual components in Visual Studio's Design view, you need to configure ...").

An example of a Telerik visual component in the XAML:

I have written my on editor for a property in a propertyGrid. Everything works as expected, but for best user experience i want to hide the expand button on the propertygrid for this property. Can someone tell me how to do that?

I have been scratching my head for days understanding how to fully describe a block to insert in DXF. For background I am interested in the rules and behaviour of how to do this, not simply trying to find an existing library.

I can create a block in dxf, lets say this is a simple cube. I can then in the Entities section insert this block. To do this I enter the coordinates relative to the object coordinate system codes:(10, 20, 30), and the normal vector of the object codes:(210,220,230). There is also a value to rotate about the normal vector code: 50.

So there are two things to do:

1. Calculate the normal vector for my object
2. Calculate the object co-ordinates, given the world coordinates for the object.

To calculate the normal vector, I use quaternions to calculate the rotation applied to the world z-axis (0,0,1) if a yaw, pitch, or roll angle is applied (if not, I simply use the world z-axis). I can use the same quaternions to calculate the arbitrary x and y axis using the same rotation for each of the real world x and y axes. For those looking for more info, this link has a very clear explanation of how to calculate them. https://danceswithcode.net/engineeringnotes/quaternions/quaternions.html

To help you, this calculator can help confirm if this has been implemented correctly or not by checking the results:

Then to calculate the object co-ordinates I simply cross multiply the world coordinate with each of the arbitrary axes/normal axes.

For most scenarios this appears to work. However I am left at a loss for additional rules and requirements which I cannot see documented anywhere:

1. If only a yaw angle is applied (rotation about z), then the normal is still (0,0,1). We need to apply a rotation about z in the scenario that pitch and roll are zero.

2. If I alter the pitch, the normal vector can change from a negative y-coordinate to a positive one. This change in slope appears to affect the direction the vector is headed and if positive, requires a rotation about the normal of 180 degrees to correct it.

3. For some unknown reason when I apply a roll angle, my object is rotated around the normal by 90 degrees, and I need to apply a correction here.

I am struggling to find any more clear direction on this online. Does anyone have any thorough explanations that describe the behaviour above, or any pointer material?

Good afternoon, I am trying to use Eyeshot in a .NET Framework Web Application to create a Bitmap image. The steps of the process in my code are the following: I generate all the necessary Entities and then I add them to a Model control that is not visible in the Web Application; once all Entities are added, I use the ZoomFit() method to zoom to the desired Entities and then I use the RenderToBitmap() method to create the Bitmap image. The issue regards the ZoomFit() method: when executed, it gives the following error message: "Control's handle must be created first". The portion of code regarding the creation of the Model control is the following:

I am learning how to use dlls and how to export them. I have created a small program that calls the different components(classes, methods, functions, ect.. ) of my dll file to use them. When I build the project I get no problem, but when I compile the test code I get this error.

Error translation: {The procedure entry point "?Start@K_WrapperTeigha_DXF_DWG@@QAEXXZ" was not found in the DLL "C:\Users\zboussaid\source\repos\WrapperTester\Debug"}.

The image shows that the start method, which is a function in my DLL file, cannot be found in the path where my test code is located. I have tried to configure my properties as shown in this drescription, but as I said, I get this error. I will be very grateful if you can help me

Given a DXF file (2D CAD drawing), is it somehow possible to rasterise only part of it? Preferably in Python's ezdxf. By the part of it, I mean the selected rectangular area, not a single layer.

Background: I'm struggling to rasterise quite a big DXF file with decent DPI in a reasonable time, so I thought that maybe there's a way to speed up the process by parallelising rasterising different parts of the drawing. I'm using ezdxf with matplotlib backend.

When reading an XLSM file with pandas I'm getting the following error:

I am trying to modify this existing npm package without much success. I have wasted several hours troubleshooting would appreciate some guidance.

I have forked the package into my Github account. I have then used npm to install the module locally (W10 running latest LTS Node).
