Alan,

Thanks for another great video. I have just recently stumbled across this great website. I also recently finished watching your 6 part series on Custom Subassembly for Overlay and Widening and was looking for a suggestion. I work for a Civil firm that does a handful of road widening projects a year that vary in width from 3 feet to 12 feet. In your opinion do you think there is a way to use the subassembly composer to smooth out the undulations on the proposed face of curb caused by the varying cross slope of the existing road?

Alan Gilbert

Hi Erik, thanks for your comment! I think a two pass design is generally the best way to do this. I don't think Subassembly Composer lends itself to helping with this situation very well (although there are some possibilities). However, customizing a Subassembly programmatically using .NET would totally be an option as you can build a single SA that can consider multiple passes. Outside of this, my feeling is most people would just run the first pass, extract the vertical location of the curb face, and then design a new vertical target that can be targeted in a subsequent corridor run. This more manual option may be more time efficient unless you are familiar with creating SAs using .NET. Hope this helps! Have a great day.

Thanks for the helpful information Alan! Do you have any videos showing the process you describe in option 2 (the manual option)?

Alan Gilbert

Hi Erik, I don't have one exactly on this topic, but the general workflow would be modeling normal and letting the curb face undulate. Then, extract either a feature line at the curb face or surface profile, add to a profile view, and create a better profile of this line. This could be done by: manually adjusting feature line vertex elevations in profile view (if very little change is needed), creating a best fit profile from the surface profile of the face, etc. Here are two videos that might help. For creating best fit profiles: https://www.youtube.com/watch?v=-VE957b29C4

For linking feature line target back to 2nd pass corridor after smoothing: https://www.youtube.com/watch?v=g5geLkfYj_s

Sounds good Alan! I'll be sure to check out the links. Once again thank you for all your help.
