Height of cone with rounded tip

Height of cone with rounded tip

Height of cone with rounded tip

(OP)
Hello, I'm adjusting the swept volume of a part that comprises a round-tipped cone (think ball point pen nib).  When I use Measure I can get the distance from the base of the cone to where the hemispherical portion is tangent to the sides, but not the overall length.  Is there a way to have SW give that to me directly???  Thanks!

RE: Height of cone with rounded tip

If you have the point in a sketch that's what I would use.  If not make a sketch with an intersection curve and create a line that has the dimension you want.  I hope this helps.

Look up Virtual Sharps in the Help file.

Thanks, but the dimension I'm looking for is to the intersection of the cone centerline with the round portion of the tip, not the projected sharp of the cone.  I know I can look at the sketch of the revolve and dimension that, I was wondering if I can query the solid model directly and obtain the distance.  If I select 'max distance' in Measure I get the red distance as shown in attached pic, not the distance to the 'tip' of the round.   

RE: Height of cone with rounded tip

I usually do as Rob suggested...not in life in general, but in this specific instance. smile  Make a temporary sketch and measure the length of a line between the two points you want to measure.

Eltron,

I wanted you to say that. },smile

This probably didn't help.

RE: Height of cone with rounded tip

This goes back to design intent. If the virtual intersection of the cone tip is important then it should be in the sketch from which the cone is revolved.

You could of course intersect a plane with the cone center line, do an intersection curve and make a construction to get the information you need. But wouldn't it be better to have this information in the original sketch if it is part of intent?

RE: Height of cone with rounded tip

If it's your height that's critical, why not create the dimension in your sketch that way?  Then double-click your revolve feature and you'll see the sketch dimension pop up.  (Even if this is a driven dimension instead of a driving dimension, this works great.)

Theophilus, that will work for me.  I was hoping the software would be smart enough to know what 'maximum' meant but I can do that as a workaround.  Thanks again and God bless!

RE: Height of cone with rounded tip

For your example I would have used the original sketch, but there are always harder problems.  One example that I always come across is cavities etc created from freeform parts.

A little trick I use for those sorts of tasks is to create a section view that then allows the maximum to be selected as a point.

For your example two section planes orthagonal and passing through the central axis would create a point that can then be selected.
