How to select through a body

[natehansen66]

I have a simple drawing of a box. Inside the box I have a sketch that I'd like to revolve. I can't select the sketch while in the revolve command. There is no left click-select other while in the revolve command, and un-checking bodies under selection priority doesn't do it either. Trying to click on the spline just results in a face selection. How can I get this done?

Hold the left mouse button down over the sketch object for a second or so. A menu will appear showing aa list of objects under the mouse cursor from which you then can select.

@natehansen66 Welcome to the Fusion 360 community.

Trippy is right. Let us know how that works for you. That looks like the beginning of a subwoofer model, is that true? 

Thanks,

[natehansen66]

Thanks for the quick replies. I've tried holding the left mouse button but I don't get an option showing selection, just delete, press pull, drawing, etc.

Yes, its a woofer box. A step file will be created for BEM acoustic modeling in ABEC3.

The results you describe are usually on the right click menu. If you use the left button, or which ever button you use to select command buttons and objects, and just press down for a couple seconds in the spot where you wish to select something, you should see the list of possible selections.

PS: If you're interested, I can share with you a parametric table for a woofer box model that varies by inside volume, width, depth, and height. The depth varies based on all three of the other variables, but you can do what you like with the formulas. Also things like thickness of panels and diameter of speaker holes are defined parametrically. 

Thanks,

Boy, I'm dense tonight. Thinking left and clicking right! I get the selection dialog now with the long left click but my spline is not on the list....just every other feature. What's odd is I can select the axis which is also within the box.

@Phil.E your box table sounds handy! I'd appreciate it if you wanted to share.

Hi @natehansen66, could you provide a screencast of what you are seeing?  I cannot think of any reason why, if the cursor is over the spline, it would not show up.

Here check this out,  I think your problem is just an interfering sketch

Here you go. 

This box is set up as a mobile audio subwoofer. So the design considerations are, in order:

1. Width between shock towers in your trunk

2. Height under rear deck

3. Volume required per subwoofer specs

Thus, depth is the remaining variable and it is completely driven by these factors. You could tweak this formula to vary in any direction, but there will always be a driven dimension.

Also note, the width, height, etc. is for the inside volume which, as you know, is critical for speaker performance. So the actual size of the box is larger on all sides by the thickness of your panel material. You must account for that outside of this parametric table. A sketch with a driven dimension at the very end of your design could keep track of the overall size of the box.

In this video, ignore the parametric table. It was set up for a multi-speaker pattern. The image below is the same parametric table but for only one speaker.

 Here is the table:

@jasonhomrighaus thanks for that. Turning off my other sketches via the browser did the trick. Thought I tried that last night but apparently not. 

@Phil.E thanks for the table one of these days I'll give it a go.
