hollow loft to extruded truncated cylinder

[jbpoole7777]

my loft keeps failing.  I am unable to select the inside end surface of the extruded hollow cylinder as a loft surface.  I suspect it has something to do with the project command but I do not understand the project command.  Any help is appreciated.  Thanks for your time.

You are missing a dimension and you did something wrong with the Rectangle. (I am going to guess that you did not click ON the circle for the corner of the Rectangle.)

Attach the *.f3d file here.

understood.  blue = no reference to origin...no constraint to origin

Nope.  Could be missing any references.  Look at your Rectangle.  (Attach the *.f3d file here.)

I am manufacturing portable cylinder shaped bluetooth speaker enclosures for personal use.  Will create enclosures with 3d printer.

With what you have shown so far, with there be three parts, the central part and two end caps, or will the end caps be more than one part each end?

Are the two end caps identical, or is one end different than the other end?

[jbpoole7777]

3 parts.  2 identical end caps

As I suspected - you missed the circle with your rectangle.

Add a Coincident constraint between the corner of the rectangle and the cirlce.

What do you notice about the Rectangle?

Also, you added an unnecessary horizontal line from the Origin to the left.

Go ahead and leave that unnecessary line in - but change it to Construction.

Nice - that will make it easy.  We will be done in 10 minutes.

Extrude the sketch 125 as shown (be sure to select inside the circle and above and below the rectangle, but not to the front of the line as shown).

Make Sketch1 visible again.

done...and fixed my sloppy rectangle

I made some guesses on your true Design Intent (see Attached versions).

In Version 2, I suspect that you will want the holes in the end of the Tube as a different size (threaded) than the holes in the End Cap (clearance), but since no communication - I left them both the same size.  They can be edited at any time.

I have a Loft example too.

thanks for the designs.  I will go through both to learn how to repeat this.  I will post my final design for critique.  Thanks again.
