How to build it (one solid mesh)? I`ve done that lines in illustrator (with dimensions). I would like to build it but I don`t know how. I tried loft with small caps. I tried revolve rail also. Any tips?

Hello,

It's more helpful if you are able to provide the 3DM file.

Sorry. This is 3dm.

Hi bartosh, one way is to do a Construct > Network as in the attached 3DM file.

Often times though it is better to avoid putting in tightly bent corners in your profile curves like you have here:




You can usually get better results by leaving those areas to be sharp and building an initially sharp cornered base shape, then using filleting to round off the sharp edges, rather than drawing all tightly bent transition surfaces directly in your starting outline curves.

See here for a kind of generally similar situation, where it shows how instead of putting in tight corners in profile curves you would instead build an initially sharp cornered object that then uses filleting to round things off:

Thanks.

I`ve created sharp corners to make fillet after that (after making network). Unfortunately bottom is gone and there are both ugly caps. How to fix it with sharp corners to do later fillet on that.

There is only the perimeter of the bottom on your file! ;)
And this one is not "flat" !

Hi bartosh did you possibly post the wrong file? The one you posted is almost empty and doesn't have your shape in it.

re: sharp edges - most likely the problem is that you have "getting very close to not sharp" edges in these areas here:




that makes things difficult on the filleter to have surfaces come to almost be tangent to one another like you have there instead of more fully sharp to each other. The fillet becomes very very tiny or possibly disappears altogether in those smooth or nearly smooth spots.

When I was talking about making things sharp I mean a lot more sharp yet and without so much remaining bending in the surface shapes like you've got.

More something similar to this:

Start with an extrusion of a base form:




Use boolean difference to do a side cut to produce the sloped front:

Seem to work Ok when using sweep maintain tangent option. Uncheck maintain height.

I deleted half of your curves first and then mirrored the resultant surface after the sweep.

Thought I'll give it a go :) hows this? broke the curves into 3 groups and used network...

Hello,

Blend works quite well on this shape with just a couple of problem areas where the surfaces pinch. If possible you could run your curves past your finished model, Extrude or Sweep those construction surfaces, perform your Blends and then perform a final trimming operation on your surfaces before Joining them and capping the object into a solid.
