How does one trim only specific co-planar parts off a solid?

Anonymous
Not applicable

Student using Inventor 2019 on Windows 10 here.

 

I tried to trim one side off this c-channel using the "Trim Solids" feature using the "Trim Solid" feature using the plane in picture 1.

 

However, doing this seems to trim off both sides of the c-channel (as shown in picture 2).

 

What I want is what's shown in picture 3; I got this result by drawing a sketch with a rectangle and using the cut feature. This method feels sloppy, and I can imagine, for more complex parts at least, not ideal. 

 

How can I get the same solid in picture 3 without having to draw a sloppy sketch?

I want to trim just the top side of the c-channel.I want to trim just the top side of the c-channel.Using the "Trim Solid" feature gets me this.Using the "Trim Solid" feature gets me this.This is the result I want, but without needing to draw a sketch like this every time.This is the result I want, but without needing to draw a sketch like this every time.

Split the part horizontally into 2 bodies. Trim one of the bodies. Then combine the 2 remaining bodies to one solid.

Do one neat sketch and Extrude-Intersect what you want to keep.

(See Attached)

 

BTW - this entire part could have been modeled significantly easier technique.

 

Edit: Oops, I made a mistake and cut off the fillet. Back in a minute.

Remember, just cutting away the flange you will still have the radius on the back of the part. Is that what you want, or for it to be square?

It is fine if it's left rounded because this is how an actual cut would look on a bracket like this.

Another possibility-- just create a trim surface like so:

Edit: the surface isn't actually necessary, the sketch alone can be used as the trim tool.

Hi Guys,

 

There are indeed multiple ways to do this. Or, you can use Thicken command -> Cut to remove the unwanted portion. Thicken -> uncheck "Auto-Blend" option -> Cut -> select the face -> set distance equal or greater than Thickness.

Many thanks!
