So notice, as I select this edge, head over to Extend and heading over to front view, notice as I grabbed this arrow, it follows that top edge. For the type, I prefer all edges selecting this surface and selecting OK. I'm going to head over to Surface under Modify, and selecting Untrim. Notice the stop edges, following a curve with our S as surface selected. And before we select untrim, let me show you it's a front view. I'm going to select this surface, which is all under this unstitched folder. And I prefer capturing the design history and notice the surface bodies in this design. I'm going to double click on this, let me head over to our main file and save the right clicking. This file is a step file that has number off surfaces. This time let's discover it's performance with an uneven surface. We have a blade around untrim using a planar surface. Enabling keep copies selecting, OK and let me turn off the visibility of our original surface. So notice, it batched up those defined edges. For manual, I'm going to enable edges and this time I'm going to select this edge and this edge. Lumb at the select faces, selecting this face. And turning off the visibility of that newly created body, repeating Untrim, right clicking to access our marking menu. Enabling keep copy once more, selecting OK. Selecting this face, notice it converted the curved edges here and created another rectangular surface. Selecting this, as I select this face, notice that external edges are the outer edges off this face. Moving forward, let's discover the third type, which is external edges. Selecting, Keep Copy, selecting OK and the turning off the visibility of that newly created body. So that means the internal edges are this circular edges prompted to select a face, selecting this face and notice we have retained these two curved edges. I'm going to right click, add a selecting repeat and trim, this time, the type to be internal edges. Notice as I select, OK, we now have the converted body and the original body. In addition, we can create a new surface body by enabling keep copy.
In addition, notice we have the option to extend this, which means, from this borders, as I key in 10 millimeters, it extended that up to 10 millimeters. So with that, I'm going to select this face and notice, it consumed all edges and created a rectangular surface. Prompt it to selected faces, let's start off by discovering the all edges type. Let me turn off the visibility off our solid body and zoom in, as I head over to modify and select Untrim. Notice now our bodies folder, we now have a surface body.
Basically it extends trimmed surfaces, fields, gaps, holes, or empty regions that may quickly create a surface by heading over to Create, selecting Offset and I'm going to select this face, all this arrow up, operation new body and selecting OK. The trim command is simply located in design workspace under surface stab modify, and untrim. Today, we are going to discover the untrim command in fusion 360. Hi everyone and welcome to another Fusion 360, tips, tricks and techniques.
