I create a junction: road 1 and road 2. But how do I can addition to road 2 an IP what is on road 1?
Thanks!
When creating the horizontal alignment for road 2, just use point selection method 'Point', and select the point from the master string from road 1.
I used to "Quick Horizontal Alignment => Horizontal Design". You mean I use Snap or XY Keyboard Entry?

Use Snap, and select the point on road 1.
You may need to change the MX_SNAP configuration variable to help with the snap mode.
1. Use Filee > CAD Menu - to show the CAD menu at the top
2. Select Workspace > Configuration to show the configuration dialog box.
3. Select the category All(alphabetic) in the left list, and scroll through all the variables on the right to the MX_SNAP
4. Edit the variable so the value is set to MASTER - the other option is GEOMETRY. This will mean that it will snap to points on master strings rather than points on geometry string, so you can access the points that are not tangent points.
5. Hit OK and exit the configuration dialog.
You may need to stop and start MX to have this change implemented.
I had created profile of Road 1, then I want to create Road 2's profile which the last point of Road 2 on the alignment of Road 1, but has error. In the Quick Vertical Alignment, I chose Add Collinear Profiles:
Collinear Profile Model: Design (because the Road 1 at the Design model)
But it has error. I cannot create profile.
Make sure you add the carriageway edge of the first road before doing the profiel for road 2. When it is taking the colinear profile, it should find the carriageway edge and the centreline, so it has 2 points to draw.
