Christmas Ornaments

 I'm drawing and 3D printing Christmas ornaments. They were modeled in Autodesk AutoCAD and Fusion 360. I used the 0.2mm and 0.4mm hotend assemblies on my Bambu Lab X1 Carbon for printing.

2024 Ironman World Championship

So, I have an opportunity to race at the 2024 Ironman World Championship in Kailua-Kona, Hawaii. My entry is through the Ironman Foundation via a charity entry. Information about the Ironman Foundation and the charities are in the link below. Please help get Team Ryan to 2024 Worlds by donating in the link below. If you have any questions about Ironman Foundation, the charities and Team Ryan, please let me know. More information to come. Thanks!

Autodesk University 2023 3D Printed Chip

 I created an Autodesk University chip I plan to hand out during the week of AU. I used AutoCAD solids to create the model. As for the QR code, I converted the QR code image to DXF and cleaned it up in AutoCAD. I tested the QR code with my smartphone while in AutoCAD and then in the Bambu Lab Studio slicer software. It worked so now to 3D print the model and test the QR code. I used Numakers PLA filament in three colors. The QR code works but I feel it can be improved. More to come!

Here are a few updated 3D prints. I used a 0.2 mm print nozzle for better accuracy. The downfall, it took twice as long to print compared to using the 0.4mm print nozzle.

3D Printed Miniature Traffic Control Box

I created a miniature traffic control box for a co-worker who is into miniature LED stop lights. The box will house the electronic controllers for the LED stop lights. The model was created in AutoCAD 2024 with 3D Solids then exported to a stereolithography (STL) file for slicing in the Bambu Lab software. I used yellow Numakers PLA+ filament. Total print time was around 14.5 hours. I had to make a few adjustments to the print speed and temperature to use the Numakers PLA+ filament.

Bambu Lab 3D Printer

My Bambu Lab X1 Carbon 3D printer has arrived. I test printed the Benchy boat. Everything looks good and printed fast. I'm looking forward to printing my CAD models. Stay tuned!

XREFs on Layer

Over the years supporting AutoCAD/Civil 3D, I have been asked, where are my XREFs?  Co-workers have placed the references on the current layers and turned off that layer. I wrote a simple lisp routine that will place the reference on a specified called "G-ANNO-REFR" which can be changed to your company standards.

The lisp routine uses the "XA" command (which can be changed to your likings). XA is a default command for XATTACH. Once the lisp routine is set in the CUI startup, it will override the default "XA" command. Run the XA command to attach a drawing. Once the drawing is attached, the previous layer will be restored.

Items in red can be changed per user preference.

Cleanup the "Temp" folder!

Over time, the c:\Users\%USERNAME%\AppData\Local\Temp\ folder will collect Gigs and Gigs of files from software. It's best to clean it from time to time but make sure there is not anything useful in this folder before deleting. Once it's gone, it's gone. I am not responsible for anything that is deleted. You can navigate to the folder to manually delete the files and folders or create a batch file to delete the files and folder with just double click. I execute the file about once a month to clean the Temp folder.

Here are the steps to create the batch file.

1. Open Notepad.
2. Copy and paste the script below into the blank Notepad file.
3. Click File then SaveAs.
4. Click the "Save as type" pull down to select All Files. This will allow the Notepad file to have another file extension type.
5. Name the file to your preference with a .bat extension. I named the file "Delete User Temp Files.bat".
6. Execute the batch file. You'll see Command Prompt screen appear as it's deleting the files and folders. It will not delete files and folders that are currently being utilized by the OS or open software.

Renaming/Renumbering Civil 3D Alignment Curve Segments

When updating an alignment with new curves or replacing curves, the curve segment name/numbers will be out of order. The curve name/numbers will display also display out of order in the Superelevation Tabular Editor. To rename/renumber the curves, follow the steps below.

1. Select the corridor.
2. Click the Superelevation pull down on the Ribbon.
3. Click Calculate/Edit Superelevation.
4. Click into the Curve Name field to rename the curve.
5. Close the Manager.
6. Open the Superelevation Tabular Editor to view the updated curves.

360 Degree Animation

So, I created a shared use path in Civil 3D for a work project. The path has a bridge which I modeled in AutoCAD with solids. The bridge is just for show until our structural team designs the bridge. I created a 360 degree video using Twinmotion. My workflow is Civil 3D/AutoCAD > Infraworks > 3DS Max > Twinmotion. I had to add metadata to the video using a metadata injector in order for YouTube see the 360 video. The 360 degree video can be viewed on a PC, smartphone, VR headset and a VR Google cardboard type. This process in Twinmotion can be very time consuming. The video took about eight hours to process. Below are my current PC hardware specs.

ASUS ROG B550 Motherboard.

AMD Ryzen 9 3950X 16-Core, 32-Thread CPU.

64 Gigs of DDR4 RAM.

NVIDIA GTX 3090Ti Founders Edition GPU.

ASUS ROG STRIX 1000G PSU.

Autodesk Civil 3D 2024

I'm testing the new features in Civil 3D 2024. Looks good so far.
