Do you enter competitions like Gravity Racing, Human Powered Vehicles or Greeenpower? PTC Creo Framework extension is perfect for modelling the chassis.
Here is how it works.
- Create a skeleton part with datum points. lines and curves where you want tubing and datum planes for section orientation .
- Add the part to an assembly.
- In the assembly, use the Framework tab to select a material section and size.
- Use the Framework tools to add tubing along curves and lines and between datum points. each pipe is added as a new part in the model tree.
- Use the Framework tools to specify joints between tubes.
- Create a drawing of the assembly and add a table for total length of each section used plus a table for the length of tubing for individual tubes.
- Open each part and use sheet metal tools to split and flatten the tube to print a paper template for cutting the joint profiles.
A zip file is attached containing instructions and the files/Youtube link showing how to create a car chassis.
Do you have a KS3 project that could use Framework Extension? I modelled a log basket but it's hardly going to enthuse pupils, how many homes have log burners at home! A zip of the log basket files is also attached. Zip with Creo models and video tutorial is attached.
Many years ago when I taught, we made unicycles with students and showed them how to ride.
For fun I created a space frame unicycle :-). Zip attached.
