Web Sketch: How to Draw curved Lines
A practical Web Sketch guide for appraisers based on the How to Draw curved Lines tutorial.
Use this article when you are working in Web Sketch and need a practical reference while building or reviewing a sketch for a report. The video walkthrough is linked below, and the article restates the workflow in appraiser-friendly terms.
Watch the tutorial
Before you begin
Open the correct report and confirm you are sketching the intended subject, dwelling, unit, or related structure. If the sketch will support GLA, exhibits, or report commentary, keep your field notes, measurements, photos, and assignment requirements available while you work.
What this tutorial covers
- How to draw and review curved line geometry.
- Labels and custom labels clarify what each shape or area represents.
When to use this
Use curved lines when the improvement includes a curved wall or rounded feature that should be represented in the sketch.

Start in the correct sketch context
This section explains how to draw curves over existing shapes and more advanced patterns.
Check each shape before moving on
Firstly, grab a shape here.
Do a line. Draw this. Go here.
Shift up, shift left, and define this area.
For example, it is an above grade level one finished. Confirm that. For example, I want this to be not twelve point four, call it, um-- try to make this ten here, make it a little bit nicer.
Seven point one, make this something like, try to make it eight. There we go. Now it is a little bit nicer.
Now if you want to make this be, For example, have a curve, if I grab this, in this state here, you can do one of two things. You can grab this midpoint area and just start making a curve, or while you are in this curve state, you can use my keyboard and just go left or right either way.
You will see that when you use the keyboard, you can do more of a granular approach to it where it increments by point one square feet, or when you are just dragging it with your mouse, it allows you to be a little more flexible. Grab this again and move this. Grab this and then move this up.
Label the sketch clearly
You are seeing that the square footage is adapting in real time to this as well. For example, that one of these this is adapting to this, but now we are bleeding into this label here. To move a label, The basic workflow is just clicking these three buttons, clicking move, and now you can just place it here for instance.
It is also helpful to know that whenever I move this label here, this same position is also going to be shown in the sketch image as well, so that's also important to recognize. Now lastly, For example, the workspace includes this and I just want to rotate it. There we go.
Now to connect this to the existing shape, grab this.
Somewhat move it close to it, and then grab the keyboard and then move it here like this. There we go. Now it is connected to it.
Now that it is interacting with that, grab this, move this label, and there we go.
Practical workflow
Draw the base geometry first, then apply the curved line workflow to the wall or segment that needs curvature.
Adjust the curve until it visually matches the field condition and remains readable in the exhibit.
Review the calculated area and exhibit output after the curve is placed. Curved geometry should improve accuracy without making the sketch hard to understand.
Field review tips
Use curved lines only where the curve matters to the sketch support or exhibit clarity.
Appraiser review checklist
- Confirm the sketch is attached to the correct report and property structure.
- Confirm labels, areas, and totals match your field notes and intended report use.
- Confirm any generated exhibit is readable before relying on it in the report.
- Recheck the report section where the exhibit or calculated area appears.
