Creating recessed rectangle in tube component

Hi Guys,

I wondered if you could help me. I am trying to model a furniture component. basically a round leg with a reccessed rectangular cutout for a rectangular leg to fit in to. I seem to be having difficulty doing this.

As I could see no way to draw a rectangle on the already extruded component, I tried the following method -

First draw a circle and push pull this to the depth before the begning or top of the rectangle cutout should begin make this a component then draw a circle on top of that the same radius and draw in the line for the cut out whilst still in 2d top view then pull this out to desired depth creating the cut out then make this a component. and repeat the following step drawing a circle on that face and pulling it out to complete the depth of the leg. then i tried to explode all these components and delete the connecting faces in the hope that they merge in to one.

The first go at this I had some success and subsequently the program crashed. future attempts of deleting these lines have not been successful. can someone please help me to achieve this result. Is this the right method to achieve this or am I completely of track.

When I need to do that sort of leg I model the apron with the tenon to go into it and then use Trim from Eneroth Solid Tools or BoolTools 2 to cut the mortise and recess in the leg.

I’m not quite sure I follow your process, but here’s how I would have handled it.

  1. Click into the component so you can edit it and then make the geometry into a group if you haven’t already.
  2. Make another shape that matches the dimensions of the cutout.
  3. Line it up where you want using inference points on the cylinder.
  4. Use the Subtract tool under Solid Tools and there’s your cutout, no messy geometry to clean up.

Hope this helps.

Save yourself some time. Use Trim with the actual rail instead of Subtract with a stand-in for it. And use Eneroth Solid Tools or Bool Tools 2 instead of the native Solid Tools so the leg component doesn’t get converted to a grouup and all of the legs get mortised in one step.

On this table the mortises, slots, and dovetail sockets were all cut with the mating components using Trim.

Here’s a version that is all raw geometry and basic tools to show you the fundamentals of the geometry.
