After you've made your single line drawing and offset the straights to the correct width you will have to find the point where the two lines of one side of the straight meet. Let's start on the inside.

Step 1:
Use the protractor and make two lines that are at 0 degrees with the the inside lines.

Step 2:
measure out the distance the ends of both straights are from the intersecting point then take the avaredge of the two and extend or shorten them to the correct length. Delete all lines unnecessecary

Step 3: Using the protractor you make two lines at the end of the straights at 90 degrees. They meet the centrepoint of the inside corner.

From hereon you can do it yourself. Be sure to repeat on the outside.
Sorry Quintin, maybe I need more sleep but I didn't understand a word of that nor why you would need it

I first outline the general shape of the circuit using straight lines , then ,using the "arc" function I smooth out the corners, joining at the straight line's midpoint or wherever convenient to get the decreasing/increasing radius effect. All this before I offset anything,as I like to get my blot shape complete before any offsets are done, that way I save myself the PITA of joining sections, or trying to get the correct width for a corner and many other issues.

The discussion on Purist's circuit has been moved to it's own thread in order to try and keep this one as much as possible a generic help thread.

You know what I mean, the ...
"how do you?"
"What the best way to?"

To do buildings and 3d stuff I draw, say, a square and then use the "push/pull" button and just pull it out to whatever length you want, you can do it in any direction provided you have a plane from where to pull it and you can angle it out by moving ("move") the border line, dragging it till it's at your preferred angle.

Do you create the 3D building, or whatever, inside the track file itself, or do you create it in its own file and import it somehow?

I've gotten the hang of a lot more of the tools. There are two main things I'm trying to do now.

1. How do you make curved structures in 3D?

@. How do you do the extrusions for garage spaces while still retaining the side walls?

For curved structures it's easiest to explain with something like a curving grandstand. at 90 degrees to the track create what you'd like to be the side on view. at the front or back add the curve you want it to follow. then use the "follow me" tool to extrude it around the arc.
I've added a 4 very quick images to give you an idea

Personally I don't add that much detail for the garages, I tend to "cheat" and just draw closed garage doors such as can be seen on the second image of this design

I'll give that a go and see what I get. Thanks for the description, and the accompanying visuals.

I had to explain this basic technique to Chrispage on another thread.

Quote:
Forgive my ignorance in this!

I can only see how to make a curve in a strict half-circle. Can this be twisted to form corners with inconstant radius?
Quote:
Yes, you'd have to use multiple arcs. To create other arcs that aren't half circles you'd have to find it's centre. Do this by drawing a line at a 90 degree angle to the straight it connects to. The length of that line is the radius of the corner. Then measure out the duration of the corner you want with the protractor and make a line exactly as long as the other line. Then connect the ends of these lines and draw a third line of the same length through the centra of this line. Finally draw your arc from the end of the straight to the end of the second line via the middle line. If you've done that and you've done it exactly as I thought I wrote then you should have a constant radius curve. Use the line at the end of the corner to create the next corner or straight and then remove all guidelines.
This is so basic I'd have never expected to explain it but I'm happy to do. I'll need to post this in the tutorial thread which realy should be a sticky

Sorry, I knew it was a basic request, but as I've never used a graphic design program before I'm a bit shooting in the dark with it. Its good to have a forum like this rather than dry tutorials.

Realy it's not a problem. This section of the forum is for showing and improving your track designing skill. I am happy to help you at any time of day. I think I speak for all other members by writing that. Have fun.
