Blend curves?

Hi, I am new to Solid Edge, and I haven't been able to find a couple of things I like from other software.

Is there anything in SE like the Blend curve from Altair's Inspire Studio?

Is there an option to specify a fillet's Shape like what you can find on Moi3D?

Solid Edge has Tangent Continuous (which is essentially constant radius, I think) and Curvature Continuous (which is more of a spline profile than a single radius arc).

Nice, that answers my second doubt, thanks. But I am still unsure regarding my first doubt.

For example, see attached image, I would like to connect selected line to the other, bridging the gap with a smooth curve which automatically aligns tangentially to the end of first line and to the beginning of second line, do I have to do it manually or is there a tool in SE to make this easier?

Yeah, thats a spline. Sketch element.

No, making a smooth curve using a spline is what I was refering to by "do it manually", this usually requires at least 3 or 4 points and is a more visual than precise approach.

In Altair's Inspire Studio there is a curve tool called Blend where you just need to hover over reference objects and place starting and ending points to produce a smooth connecting curve (which you can change between cubic and quintic), and you then have the possibility of specifying the tension of the curve, choosing for each of the points if you want tangential or curvature continuity and the magnitude of the tangent at the point, and other advanced parameters. It's a very powerful and useful tool, but I haven't been able to find anything similar in SE. See attachment.

In Solid Edge it's called a Curve, but it's really a spline. You can add tangent relations to its ends, and can control it to some extent with a frame. You can change its degree and use the frame to control continuity to some extent. It is missing some fine details for control, but this is what is in Solid Edge.

OK, fair enough. Thanks for your reply.

Bridge curve in NX. If you are in Solid Edge you can try and use the command finder function! You type in the command from your other system and SE will attempt to map to their equivalent command.

Bridge curves were a wonderful thing.
