Generate a design

Generate your Fiber Design: choose a quality setting, check your premises, fix errors, refine hubs, drop assignments and blockers, then update the design.

Once your input data is complete, the Design step generates your network. You can then refine it and update it as many times as you need.

Step 1: Choose a design quality

Setting Best for Time limit
Express Quick results while you’re trying options Up to 20 minutes
Balanced (recommended) Most designs Up to 60 minutes
Extended Large or complex areas, where extra time may give a better design Up to 200 minutes

Most plans often finish well within the time limit, so treat the above information like a worst-case scenario.

Step 2: Check your premises

Generating a design uses premises from your workspace’s subscription. Before you generate, FOND shows how many premises you have left, and how many this design will use. If you don’t have enough, workspace admins can click Buy more.

Step 3: Generate

Click Generate design. FOND works through each stage, from placing drop and distribution hubs to counting materials and calculating Cost to Serve. You can leave the project and come back later, or click Cancel to stop.

When it’s finished, you’ll see Design complete.

If something goes wrong

If FOND finds problems, they appear in an Errors list. Click an error for details, and click Open feature inspector to see the affected features on the map. Fix your input data, then generate again.

Step 4: Refine the design

Once your design is complete, you can fine-tune it under Make refinements:

Refinement What it does
Blockers Draw lines that cables must not use
Hubs Drag drop and distribution hubs to better locations
Drop assignments Reassign service locations to different hubs
Reset edits Undo all your refinements

To move hubs after you’ve changed drop assignments, you need to reset the drop assignments first.

After refining, click Update design to apply your changes.

Keeping your design up to date

If you change your input data, refinements or quality setting after generating, FOND shows You have made changes that may affect your design. Click Update design to apply them.

Until you update, the Artifacts and Reports steps stay locked, so your outputs always match your latest design.

Tip: Before trying a different approach, create a new project version with Continue from most recent version, so you can compare options and go back if you need to.
