Want to copy, mirror, flip or delete any drawing selection of your architecture, interior or landscape design, or other creative sketch? Well, now you can! Below is a quick "How To" guide to get you started on this exciting way of working with your drawing.

How to Get Started with Lasso

Step 1. Tap Lasso Tool

Tap the Lasso button. When opening up the lasso tool, your interface will hide and you can draw your lasso around any part of your sketch.

Pro Tip
The lasso tool only works on drawings made in Trace. You cannot select an image, drawing, or PDF underlays that are imported into Trace.


Step 2. Select Your Layer

You can only lasso one layer at a time. If your layers are stacked, you can double-tap any layer in the layer toolbar to make it your active layer. You will see a black outline around that sheet of paper.


Step 3. Select Your Lasso Type

Choose the Lasso Type at the bottom that works best for your selection scenario.


Use the Freeform Lasso option to select around irregular curved shapes. Drag your Pencil to create a freeform curve selection.



The Polygon Lasso option is best for irregular polygon shapes. Tap your Pencil to create polygon nodes. To complete your selection, be sure to close your polygon by tapping on the Start Point.



The Circle/Ellipse option is best for circular quick selection. Press and drag your Pencil to create a circular selection.



The Square/Rectangle option is best for rectangular quick selection. Press and drag your Pencil to create a rectangular selection.


Step 4. The Edit Toolbar

Use these tools to transform, mirror, duplicate, or delete your selection.


Use these modes to resize, skew, or distort your selection.
