Fillet, Trimming and Radial Dimensioning

[ERK]

Hi All

I have some more basic questions that are driving me nuts...

1. After you draw a rectangle,extrude it, fillet the edges create a section or side view, create a viewport then place it on your page to annotate. Why is mine showing a segmented line that can not be radial dimensioned? It says the filleted area is not an arc??

2. If I draw a 2D rectangle, fillet the corners (1/4"), then try to trim off the lines that extend past the fillet (looks like a little triangle), the whole line deletes (I am clicking on the part of the line I do not want)?

I have attached a file with notes showing what I am having problems with.

Thanks to anyone who can help, Im going nuts trying to figure this out.

There are 3 modes for the fillet tool. (the "U" key cycles between them). See callouts on design layer of attached.

I don't think there is a good way to dimension the fillet.

I always add a "secret" circle in the annotations layer of the VP and dimension that. It's easy to do, the fillet and it's center point are snappable.

Maybe someone know if there is a real way to do that....

Although the 3D Fillet Procedure utilizes an initial arc by radius,

the resultant shape is a polygonal mesh surface.

Therefore, the Section Procedure takes a cross-section sample of the mesh

resulting in a segmented curve ( based on the frequency of the 3D resolution ).

Dare I mention my hope for proper 3D dimensioning again...I'm getting bored with asking for it so it must be really dull for others to listen to me gripe on.....but hope springs eternal!!!!!!!

Neither is a round wall an arc but VW manages to be able to apply a radial dimension without any trouble.

The fillet tool just needs to produce an object which remembers where it came from.

...which would mean it could be part of the history tree and save alot of time when editing.

So basically the only way to dimension the radius is to create an arc with no line correct? Any thoughts on my trimming problem?

I think so...

Use the 3rd mode of the fillet tool.

I think VW and Parasolid maintain the fillet as a true curved surface. The tesselation happens when either being sent to the graphics driver for display or to the section viewport routine for conversion to 2D. If the section viewport routine actually created an arc or NURBS from this section plane we could dimension it.
