• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

SBuilderX 3.15 Freezes on "Details" Window

It's hit and miss but my SBuilderX 3.15 is freezing when looking at the Details windows in the Object Properties pane. Though I can move the figure and change the numbers, it's extremely slow. Nothing else seems to work while the freezing is taking place. Using Windows 10. Appreciate any suggestions to fix this issue.

Thank you Gary. I should've said that the version I'm using is 3.15. It's what shows on the "Help/About" menu. I've edited my original post.
IIUC, you are referring to:

SBuilderX Menu > Tools > Object > SBuilderX Object Properties dialog > {Lib Objects} tab ? :scratchch

Be sure you run SBuilderX from a Windows Shortcut link edited to allow SBuilderX.exe to "Run As Administrator".

Also, be certain that you have the proper version of FSUIPC installed for your installed numeric version of P3D: :pushpin:


If the above suggestions do not resolve the issue, let me know. :)

I'm referring to manipulating/rotating the image that appears after pressing the Details button highlighted in this image:


Either the entire PC freezes or it's very slow when rotating the object image here,


I do run SBuilderX as an administrator, and I do have the latest FSUIPC version.

Thank you for your help.
Hi David:

Which version of Windows-10 installation do you have:

32-Bit (aka "x86" single core CPU computer)


64-Bit (aka "x64" multi-core CPU computer)

If you have a 32-Bit version of Windows-10, see:

[SBX315 install path]\SBX315\ReadMe315.txt:


The files contained in the archive SBX315.zip solve some
problems found when running SBuilderX 3.14 on Windows 10
operating systems. A full repository of the source code
can be found in:


SBuilderX 3.15 does not relay on any external DLL file to
read and write Esri shape files. A relevant number of
known bugs have been corrected as well as some enhancements
have been added.


You need to have a complete and running version of SBuilderX
3.14 installed in your system. Then you simply replace/add
the files contained in the present archive. It is advisable
that you create a backup copy of the files that will be
replaced by the present ones. A set of plugins for different
Tile Servers is included. The DLLs are of the anyCPU type
and were written by Richard Ludowise.


SBuilderX 3.15 is a Visual Basic programme and requires that
you have .NET Framework 4.7 installed in your system
. If you have
not it installed, you can get it here:



DirectX3D version 9 also needs to exist in your system.



SBuilderX 3.15 was compiled with AnyCPU as target. Therefore it
runs as a 64-bit process on x64 machines and as a 32-bit process
on x86 machines. However, it uses slimDX.dll for which there
is no anyCPU version. If you are running on a x64 machine you need
to do nothing. If you are running on a x86 machine you should make
a backup copy of the file slimDX.dll and then rename the file
slimDX-x86.dll to slimDX.dll."

Hope this helps. :)

I have Windows 10 Pro 64-bit. Per the ReadMe315.txt file, looks like I need to have "... a complete and running version of SBuilderX
3.14 installed in your system" before installing 3.15. Does this apply even with Windows 10 Pro 64-bit? I have .NET 4.8 and DirectX 12. I'm assuming these meet the .NET 4.7 and DirectX 9 requirements.


I recommend that you instead try using the newest Windows-10 compatible version of SBuilderX 3.15:

"I have made a full zipped version of the program, with all folders filled for immediate use without a previous installation of version 314:"

Full SbuilderX v315

Please reply here to indicate whether or not this is the version you actually have installed before downloading / installing anything else, :alert:

Gary, I installed the Full SbuilderX v315 you posted into a separate folder and it works flawlessly. I will proceed with using this one from now on. Thank you for your help in solving this issue.
