Loft to Create Tapered Insert

[rowland4MB3K]

Hi everyone.

I am very new to CAD work and I am trying to create a tapered insert for a culture plate insert.

The body on the left is my current design, but I have found after resin printing that the culture plate has a taper at the bottom that is approximately 0.150mm narrower that the top. This results in the insert not fitting to the bottom of the culture plate. I created two new bodies with the correct (I hope) outer dimensions, but I am not able to loft them together. I tried to use the "Draft" tool, but it does not maintain the 1mm wall thickness I need.

Body35 is my current design, Body37 is the top of the insert and Body38 is the bottom. I have gone through tutorials but I cannot get this to work.

Fusion Loft has never been able to Loft hollow (walled) profiles.

You need to Loft the Top and Bottom external profile, for a solid block of material.

After that you either Shell for wall thickness, or Loft as a cut the internal profiles.

Might help...

Thank you. Is there a way can do that without having to connect each section of the external profiles?

I could not get the Loft function to work, so I have used the Draft tool on the external and internal walls. It looks a bit thin, but I am waiting for it to finish printing to see how durable it is.

Hi,

Project the profile and create an offset on the tapered side (here = -0.1 mm).
Then create a loft body between the outer contours, from which a second loft body is removed using the Cut option.
