negative countersink

Hi,

Does anyone know how to get a countersink hole from underneath a part?

I have a plate and I have put the point on the underneath. The workplane is set to the underneath facet.

When I choose counter sink it does not work. I think its because the  Z axis changes direction when the work plane is set underneath.

Cheers,

MPC.

Hmm,

I am using TC16 BTW.

If I set the reach as normal and set the depth is okay.

If I use Reach as through then it does not work.


Anyone know what through does?.


Thanks

re: Does anyone know how to get a countersink hole from underneath a part?

Seems to work OK here.
I drew out a Box, changed the WP to the top and placed a couple points. I used the Hole tool to place some Counter Sink holes at those points. I then reset the WP to World (which is where the bottom of the box is) and placed some points. I used the Page Down key to select the bottom facet, then select the points. The counter sink went up into the box as expected. I could have also rotated my view to select the bottom facet.

Hi John,

Thanks for the reply. did you use the Reach through mode on the countersink properties.

I can only get it to work if I use the normal in set the depth.

re: did you use the Reach through mode on the countersink properties.

I tried all three "Reach" features. When I use Normal, TC shows a preview of the Hole before I select Finish. When I used "Through" and "Next Face", only the Point object lit up, but no preview of what the hole would look like. The Hole appeared when I selected Finish. I looked in Help, but they don't describe what "Through" and "Next Face" are or their differences. To me, they both do they same thing, which leads me to believe there is something broken here; I just don't know what.

After using Page Down, I click on the green highlighted "Face", then click on the Point to select that, then Finish.

I thought I tried that yesterday and it didn't seem to work; today it does. Thank you for the education. :-)

A familiar lament. BTDT :-(
