Combining components in a join operation leaves previous edge lines.

[smallfavor]

It's not always readily apparent if a boolean has worked because the newly created solid or component retains the all edge lines of the previous bodies.   I waste time trying to figure out what's there and what's not.  I think lines that indicate edges that remain only as reference to face edges that were combined shout display in a thinner weight or some dashed form to give a clear indication of what they are or what they or not.

Faces that are truly colinear will merge, if your model shows edges where you think you should have a single face it's because of inaccuracies in your model.

Here's an example where I've combined 2 boxes, 1 face is set back 0.001mm so doesn't merge. You will get the same is one's at an angle or 2 circular faces are not concentric and exactly size for size.

The post was updated when I discovered that the operation left behind bodies or such.  The question evolved on to how to easily use the combine tool without causing a cluster f of the timeline.  There's another issue with the furom interface which is failing to post my screencasts.  Not only is the tool confusing but the help process is faulty as well.

Try using Remove instead of delete. As for the errors, pretty much impossible to say why you've got them of how to fix. Seeing the way you just ignore the warnings that delete will break things I suspect you deleted something those features used. As you say it's a pretty simple part, you just need to learn a better work flow.

The lines left behind after a combine are because you have keep tools selected by the way.

Do you mind if I request this is moved to the design forum because you'll get more help there.

sure, please do.

And this:

The error messages are not very helpful. They need to be more explicit, or with a link to more detailed explanations available. “The model is using cached geometry to solve … “ (What does that indicate as to the solution? ) “Reselect reference geometry -“ But selecting what appears to be the geometry mentioned has no effect. An experienced user may understand this explanation but an experienced user will likely not create such problems in the first place.

These tips need to be geared towards the new users and facilitate better and quicker understanding of the application, at present they just provide an irritating opacity.

Error: Combine1
Target Body Error

With the errors the best advice is fix them as soon as you get them. I looked at your file but I can't tell now what you've done, if you'd tried to fix as soon as they appear you'll know the last operation you did caused it and you should have a better idea how to fix.

 Here's how to fix the sketch plane problem.

Thanks Mark,  I'll start using remove (and someday understand it).  Also, I missed the 'redefine sketch plane in the menu.

In this thread one of the Fusion 360 teams finest describes the difference between delete a n remove.

I am encountering the same problem, but there are no differences in dimensions of the objects is there an easy fix to this?

Yes, it is very easy to fix.

File>Export and then Attach your *.f3d file here and someone will demonstrate how to fix using your actual geometry.

Alright, here you go

Sketch1 is not fully defined.

Should not be using Loft for this design.

It probably would have been best to start a new thread for this discussion.
