- Hi again,
Today I'm going to start a series of posts for the upcoming Wednesdays - How to make a study of a tunnel in C3D!
These pictures will get you an idea of what to expect during the coming posts!
The original design of this cross section is grabbed from the project "Citytunneln" in Malmö - Sweden. It's a large tunnel for trains going under the City of Malmö. (Project link)
As a start of this design I re-created the lines in the cross section that I wanted to use as links in the C3D Subassembly. The result of that is the magenta lines below.
After doing that I made sure all "vertical" links were adjusted slightly to not be straight up/down. They are moved some 1 or 2mm (part of an inch) to avoid problems with different Z-values in the same XY- coordinate.
Then I created a Subassembly using the "Create Subassembly from Polyline"-command. (Will present exactly how in next weeks post)
We need an Alignment of course...
We also need a Profile
In the end of this Tunnel-blog series we will have something like this (seen from the tunnel and out). All done in C3D without additional software.
Don't forget to check next weeks progress on this one! ;-)
Until next week - Drive safe!
Cheers! / Ove C
