Unfortunately, Shapr3D currently does not support drawing parabolic curves out of the box. With Shapr3D’s spline curve, you can only approximate it by using different number of control points.
This seems like a major limitation. I wasn’t expecting complex tools to build curves from arbitrary formulas, but I’d be pretty happy with some power user functionality and the ability to switch the type of curve/spline (quadratic, cubic, etc) so that the control points can more easily be used to build basic geometric surfaces like parabolas and hyperbolas.
I mean really if I want a nice organic looking hyperbola surface I shouldn’t need to build it in Blender, use some conversion tools/plugins to export from blender into STEP format, and then import into Shapr3D via iCloud files, because I can’t rely on airdrop, some other CAD viewer app hijacks the airdrop extents or mimetype or however Apple decided iOS would chose which app to open files on the iPad with by default.
All of that in order to continue editing the rest of my design in Shapr3D which is honestly one of the nicest 3D editors I’ve ever used. It really ruins the enjoyment I’ve had being able to work on the go, enjoying the ease of input using the Apple Pencil.
Is this kind of functionality likely to be part of the upcoming improvements to curve editing? Or is that going to focus on other aspects of the curve editing experience?
I too am trying to model a part which most of it is completed however I need to add a very exact radius of 84 deg between two planes. To create a type of bowl. How would I do this? My job is actually depending on this. I purchased this for my company with people believing in the my advice to buy this yearly fee.
I really have to agree with the gentleman above. Like why is that not one of your first priorities? Everything else seems so beautifully well thought out. It’s a real issue. And if I look like a loser I’m going to have a meltdown brother.
Can you hand sketch a profile of you parabole please. rather the actual part you are trying to create. How exact must it be to the parabole shown in the first image?
Switch your spline type to “control”. I was able to nearly perfectly reproduce that parabole profile using the spline. What kind of accuracy do you need?
(I’d send a screen shot but it’s too early for this PC guy to learn how to screen shot an iPad <= I’ll have enough coffee in me in 1 hour, maybe)
** Can you hand sketch a profile of you parabole please. rather the actual part you are trying to create. How exact must it be to the parabole shown in the first image?
Basically the width of the top of the parabola is exact at 223mm in the drawling. The width of the bottom of the parabola is exact at 130mm in the drawing and the height is exact at 70mm is all in the drawling. Those are the parts of the drawling that are done.
All that is left is if you look at the contour of the dish the side walls are straight, as in without radius. Much like a pan for gold. That is not what I need. I need that wall of the pan to have a radius to it. Like a bowl. The radius must be 84mm @ 52 deg.
Basically I will be using this drawling to convert to a car file for production. So it needs to be precise. I am still learning this program and so very newbie here. I almost have no experience in this field as is.
