Topic: Pipe Network Display | Self-Intersecting Alignment?

[BlackBox]

Regarding T intersections, the intersection wizard doesn't like it when the secondary street doesn't terminate as the point of intersection.

This.

He's what I did recently to show the extend surface beyond my design alignments. I created a "shadow" alignment that extends beyond my design alignment that lives only in my production drawings. I have the style set so that it doesn't plot and it is very important that the design and shadow alignments have matching stationing. I created surface profiles for just the extended portions of the surface I wanted to show on my sheets. I then copied my profile view style and altered it so that it was mostly unlabeled and the labels I did keep didn't plot. I laid this 'overlay' profile view directly over my design alignment's profile view after adjusting the station and elevation ranges to match.

When I used to overlay to show the extended surface profile, I only put the pipe networks in the 'overlay' profile view so that the network parts that extended beyond the design alignment would show up. I only when though this mess when I wanted to show the surface beyond my design profile.

I appreciate your sharing your workflow.

Perhaps I didn't understand fully, so forgive my asking - is that not more work than instead using 'clean' Alignments in plan only, then DREF+Promote+Rename+Extend those Alignments in your Profile drawing, and do ALL of your profile-related work for plan and profile sheets there (no back and forth), no?

How much are folks making use of the intersection wizard? I let it do its thing during most of the deign phase while things are still shifting because it locks the profiles together at the intersections. Once things are pretty much set, I work from critical points and take over the design profiles the wizard created. I review and revise each intersection so that they modeled the way we want them for the construction plans, mostly just fine tuning. Merlin the intersection wizard is not, though it does like bird baths.

I use the intersection wizard for all intersections, importing a 'typical' for each County's assemblies, and radii, but this is an area I am not happy with how it works with the extended Alignments - even when the Profile ends at the intersecting Alignment, and a Profile is requires for intersection creation, the wizard creates a four-way intersection despite it actually being a Tee. Grrr

Lately, I've found it easier to instead create my own baselines, and regions leading up to, or away from an intersection, I grade some Feature Lines, run CAPFEATURE, and add the resultant Alignments+Profiles as baselines and regions accordingly.

That is an option. For us, we are putting construction plans together while the engineering plans are going through the review process so we need the design profile and design alignment changes (name changes included) to automatically propagate through the production drawings via XREFs and DREFs. Throw in phasing on the bigger developments.

The design XREFs and DREFS take precedence over any tricks or hacks I make for the composition of production documents. If I'm going to do something goofy like the 'shadow' alignment and overlayed profile views, I'll try to limit that to a particular production drawing so it doesn't cause a problem in a future phase. Its all a negotiation with Civil 3D to produce a plan set composition you and the client are happy with. Some strategies work better than others in a given situation. I will try yours in the future.

I haven't used that Sincpac tool yet, I'll have to keep it in mind.
