Extrude to rounded triangle protrusion

Rectangle extrusion to triangle protrusion is not

conforming to surface. Rounded triangle protrusion base

edge seems to be the problem and the extrude goes through

the protrusion and seems to go under as if it cannot

detect where to stop at the rounded section and the co-

aligned and constrained top plain (just a guess though it

may be something else).

*Ok using Chrome was the problem for uploading images and files.
Used Firefox.
Thanks Solidworm.

try Firefox or Internet explorer to upload the file or images. this forum isnt compatible with other browsers, as i've experienced this in the past. BTW, have you tried defining "control points" on the sections? each point defined on section A and be connected to a corresponding point on section B,that way.

I've tried using Control Points and can not seem to get it to work.
The file is available for download if someone can figure something out that is easy to do for future extrudes.
 
you can draw Extude1 profile on the front plane to avoid

that gap as a result. or you can just select the flat side

of the gap and go to Edit menu and select remove. it'll be

filled.
Here's the part with the gap filled:

For future extrudes, if you need to select a quilt(set of connected surfaces) as a depth limit for extrudes, then you can select those surfaces, copy and paste them (Ctrl+c, Ctrl+V) and select the resulting quilt as the limit. (set selection filter to Quilt). it didn't work for this case tho.

Thanks Solidworm! The Remove method was simple and worked. I was also
able to finally round the rest of the edges. Although it still would not
allow the complete round to occur under one feature. But by making
another round feature after the first sets were rendered it allowed
them.

I will practice using quilts as you describe.

Cheers, I spent hours on this problem lol thks
 
The problem was not your extrusion, but rather your
sweep. The main side that you dimensioned was the inner
portion, yet you extrude up to the outer portion. This
was not properly aligned to the bottom
plane, even though it showed as tangent. I deleted the
right side of the sketch, redimensioned the left side and
then mirrored again. I then copied and pasted the flat
and round surface to which you wanted to extrude up to
and "voila", it works fine. The copied surface must, of
course be inserted before the protrusion.

Thks tgsp for looking into this and finding a solution.


I've tried and tried to do what you are saying and resketched so many different ways yet can never get the extrude to go to the protrusion. One step I am not sure what you mean is:


"I then copied and pasted the flat and round surface to which you wanted to extrude up to"


There is only the square sketch that gets extruded to the protrusion but it does not make sense to me that you would need to copyand past this or anything elseI can think of.


Well I don't know what kind of magic you did but if you can upload the file and maybe post a few images of how you did it that would be so helpful. Cheers
 
How do you get a part file to this forum? I would give you
the part but I can't find a link to download.
 
Ok got it ! Thks so much. I understand how to do it all now it seems it needs points on the sketch exactly where the sketch contacts the reference plain rather then just having a curved sketched line tangent to the reference plain.


Cheers thks everyone
