How to Trim Sketch Geometry in Fusion 360

How to Use the Trim Command in Fusion 360 // The trim command can be activated from the sketch dropdown list or from the right-click sketch menu. You’ll also be able to activate the trim command with the keyboard shortcut letter “T,” as in Tango, as the trim command is used quite often while working in the sketch environment.
The trim command lets you trim away sketch geometry to the nearest point of intersecting sketch geometry.

Incredibly easy, like most things in Fusion 360, just sometimes hard to find on your own. Thanks!

[@TheCGMaximum]

Great work explaining the tool in different environments, it was useful to see that splines don't behave differently from other shapes when being trimmed. Keep up producing clean tutorials like this, they're some of the most professional videos I've come across!

[@ProductDesignOnline]

Thanks, Matthew! I appreciate your kinds words and I have no intention of stopping any time soon. Thanks for your support. Cheers, Kevin :)

[@yareps]

Thanks, Kevin. I always learn something from each of your videos.

[@ProductDesignOnline]

You're welcome, A Frend. I'm happy to hear that and I appreciate you taking the time to watch and comment. Cheers, Kevin :)

[@khalidhashimeh]

Thank you for all the videos..we all appreciate a video about constraints in Fusion 360..you have the gift to explain things so clearly like no one else..I highly recommend your KZbin channel..

[@ProductDesignOnline]

Thank you, Grizzly Hunter! I really appreciate the kind words and I'm happy to hear you're learning from my tutorials. I really appreciate your support! Cheers, Kevin :) ps. For anyone interested, here are two videos on constraints: 1) How to manually add sketch constraints: kzbin.info/www/bejne/eHjac42AZpl-frM 2) How and why to fully constrain your sketches: kzbin.info/www/bejne/eWKUfWRpa7pjrLM

[@danh9002]

Thank you so much for this tutorial! You are awesome. This was exactly the command I was looking for!

[@ehjones]

Great video, thank you! To help maintain constraint geometry, create your initial basic shapes with construction lines (dashed), then trace over the top with regular sketch lines to create the necessary profile shapes. Any parametric constraints you use on the basic construction lines will be preserved, without trimming warnings. In your example I might use centre point arcs to trace over the circles.

[@ProductDesignOnline]

Hi Ed. Thanks for sharing this tip with the community! Cheers, Kevin :)

[@4funrc11]

@Ed Jones - Hey, :) Thx. I'll be trying out your suggestion.

[@4funrc11]

Hey, :) Thx. Certainly picked up on the "unknown... left-click and drag". Helpful.

[@ProductDesignOnline]

Thanks, 4FunRC. I'm always looking to share the little tips and tricks that make a huge difference in workflow efficiency. I'm glad you found this one to be helpful! Cheers, Kevin :)

Great video for the trim tool in sketch mode. I was hoping to find a video about the trim tool when using sculpt mode.

[@Mup2610]

Hi Kevin. Really enjoying this series and it's helping me learn Fusion 360 for use with my 3D printer. One problem I keep running in to is what I believe is referred to as fit and tolerance. Many of the parts I'm making need to join together and I tend to just make a hole of size X and then a pin of size X - 0.15mm. It then takes me a few more prints to get the best size for the pin/hole. Thought it might make a good topic for a future video. Thanks

[@ProductDesignOnline]

Hi Anthony. Not sure how I didn't see the notification for this comment :) Anyway, thanks for the suggestion! I've had a few other people bring this up as well...so I've added it to the list of video ideas. I will definitely have to do this as some point. Cheers, Kevin :)

[@MaxGoddur]

Let's say you have a threaded hex bolt and a hole is there a way to mate the two so the threads are adopted by the hole?

[@ProductDesignOnline]

Hi Rud Dog, I would recommend you use a cylindrical joint. Then, try to apply a motion link to set the ratio between rotation and movement. Cheers, Kevin :)

[@ecophage]

I created a spiral in the bodies but i cant get it to integrate into the sketch. Its permanently separate. they overlap. They can each be selected but i want to modify the profile of the spiral body to attach it to the mounting ring i sketched so i can cut it out. What am i missing

[@ecophage]

ooooh kinda got it, selected one edge line copy then new file paste it was just the sketch line spiral i needed redid ring to it

[@samaeybelgium]

So...what's the solution for the firtst model?

how to trim old file.i can not trim

[@SSGWEREWOLF]

Videos are good but need to be updated to latest version of the software. My screens are not the same as yours. Also trim and other options not functioning. How do I get them to start working ??

[@ProductDesignOnline]

Hi, SSGWEREWOLF. The only thing that has changed with the new UI is that all the sketch features are now located under the SKETCH contextual tab. More about the changes can be seen here - kzbin.info/www/bejne/qqa9q3uZoqunnZY You will have to be in an active sketch environment for the sketch tab to appear in the toolbar. Otherwise, you can access sketch features with the shortcuts box, using the keyboard letter "S". In regards to the trim feature, could you elaborate on what you're experiencing? The trim feature has not changed in recent months. Cheers, Kevin :)

[@stardustypsyche8468]

I imported an SVG. Those line segments don't seem to be treated as "sketch geometry". How do I create an intersection? The trim tool is ignoring the apparent intersection of a line I drew in my sketch that crosses a line segment in an imported SVG image. So, the trim does not work in that it does not trim only to the intersection. The apparent visual intersection does not seem to be a recognized intersection for the trim tool.

[@ProductDesignOnline]

Double check that the geometry is not fixed, as it will be upon importing via the SVG route. If you see green line color then that means it's fixed. Use the fix/ unfixed constraint so that you can alter the sketch (from the SVG). SVG's often convert to many tiny little line segments, so using the trim tool may or may not be helpful. You will want to zoom in to take a close look at how much geometry is making up the shape. It really depends on the shape so it's hard saying without seeing what you're working on. Hope this helps! Cheers:)

[@coontabean]

I'm trying to trim several lines and it was working fine until the last line. It highlights red but won't actually trim. I get a warning pop saying "constraints and/or dimensions were removed during operation." How can I trim the line?

[@ProductDesignOnline]

Hi coontabean. This one's hard to answer without seeing the specific geometry. Could you share a link to a screenshot?

[@PandaFPV]

I don’t know why this isn’t working for me. I drew two circles like you did. Pressed trim and nothing gets highlighted. Circles are blue and not yellowish like yours. Where am I going wrong with this?

[@ProductDesignOnline]

The background color was changed from yellowish to the blue when you have a closed profile. As far as the trim not showing up... It's hard to say without seeing your screen. Can you share a link to a screenshot or screencast?

How to add holes in side walls of cylinder

[@ProductDesignOnline]

Hi, G.Mahesh. You'll simply need to create a construction plane. You can use a number of different construction planes. You could use the tangent plane, which works great with cylinders, or you could create an offset construction plane by offsetting the plane from one of the origin planes. Cheers, Kevin :)
