It's good fun to go on safari trips with the UF1 out of bounds
It does work online. However you have to make sure your host allows the InSim to work. There might be firewall restrictions concerning the InSim port. ClaViCo AP has been on for a few days on my testserver without any problems. I did have to add some inbound & outbound rules in the firewall. Your own firewall might also crash the party so these have to be taken into account. Single player support is on my todos list to make it a more accessible for novices.
Yes - add one ramp,position where you want,add 2nd beside,adjust the position you need etc. Quite time consuming thing,but you see the results alredy in other posts.
You do realise you can make use of the Indexers? These indexers are used to increment or decrement the value in question (W:, L:, A:, H: ) so each time you click the "Add" button the next object will be added incremented/decremented by the values of the indexers. They are very usefull to quickly make patterns like ovals, bankings etc.
EDIT:
For example:
To make the pattern you see in the screenshot the following Indexers values were used W:20 L:155 A:0 H:3. Once I setup the Indexers I did have to click "Add" frantically 85 times though (the pattern you see is made of 85 Ramp2 objects). Next release might include a faster way to make your pattern so you wont have to click "Add" frantically.
