Chamfer

Keith Frost

this may be a stupid question, but how do you specify an angle other than 45 degrees for a chamfer?

Keith Frost

just to clarify, chamfering a solid not just lines.

Yeah, it appears the dmchamfer command can only do a 45 degree chamfer. There may be a better way, but you could get a chamfer at any angle by offsetting lines from the edge you want chamfered and using the slice command.

You can also use the chamfer command (as opposed to dmchamfer).  In that case, provide two different chamfer distances.

Tijs,
  When I use the chamfer command on a solid, it does work but there seems to be no way to predict which way the chamfer will be drawn. For example, I can specify distance 1 as .250 and distance 2 as .500, but I don't know which plane will take the .500 and which the other. Am I missing a step?

Here's how it goes :
: chamfer
: (I pick an edge on a solid)
: Enter surface selection option : Next / OK   (It seems not to matter which is chosen)
: Chamfer distance on first entity : .250
: Chamfer distance on second entity : .500
: Select an edge or loop : (I select the same edge - redundantly)

Then a chamfer is drawn. If I am lucky, it is done the way I need.
I am using Bricscad Pro V12.1.23 .

Please ignore my previous post. For some reason it didn't post correctly.

Well I guess I just don't know how to get anything posted correctly!

Hello Randy,

I just tried myself.  Apparently the normal chamfer command does not have a proper flow and highlighting when used on a solid.
The planes can be switched by using the "Next" option once when this message is displayed: "Enter surface selection option: Next/:".  However, no highlighting indicates which plane is selected as the first plane.

The behaviour of chamfer will be re-evaluated.  Feel free to also post a support request about this.

Tijs,
  Thanks for the reply. I think the best overall course would be to add the necessary prompts to the DMCHAMFER command to choose an angle and reference surface.

Thanks for all the feedback
