helicalgearplus's Issues

Internal Gear incompatible with Base Feature Mode

The internal gear option is incompatible with base feature mode.
The gear generated has an incorrect geometry.

Feature request: Bevel gears

It would be great if this add on would be able to do bevel gears as well. The only working addon that exists costs 20$ for th basic version. Other then that there does not seem to be anything out there.

Thanks for the great addon so far!

Positioning sometimes doesn't work when in direct modelling mode without preview.

Found in:

Addin version: 1.0.6
F360 version: 2.0.7830

Steps to reproduce:

• Enter direct modeling mode.
• Select a SketchPoint as positioning center.
• Do not enable preview
• Press OK

Expected result:

Gear should appear on the selected point

Actual result:

Gear appears unmoved.

Notes:

No exception is generated.
Works fine when using preview

Workaround:

Use preview

Create testing procedure

Due to the increasing complexity of this Add-In testing is becoming more and more time-intensive. Simple bugs like #19 where missed.

A semi-automatic testing procedure that generates several gears based on a list of parameters for visual comparison, as well as a file to compare them to would help with future development

A list of parameter combinations of interest would need to be created.

feature request: elephant foot bevel or fillet option

Wondering if you can add a chamfer or fillet option for the edges to prevent the "elephant foot" effect on the first layer when printing. It is very hard to select all of the edges in a high tooth count gear. Maybe there is an easier way to select the edges and use the standard tools.

Hello i cant make worm gears. Only i have 3 options.

Radial standard addendum and dedendum no effect

Example with helix 0 deg.

Not an issue

Nothing to report, just wanted to say thank you for creating this tool. It's amazing work that's super useful, easy to use, and sincerely appreciated. Plus you made it free. Thank you.

After installing via app store, not seeing menu options to use add-in

I've just installed the macOS version of the add-in using the App-store. After restarting Fusion 360, I can't find the add-in anywhere. It's not under "Solid > Create".

I'll try downloading the .zip file directly and installing it through the "Utilities > Add-Ins" menu to see if that makes a difference.

Add Support for Auto Meshing

Positioning and Rotating Gear to mesh with a selected other gear would be a nice feature.

Internal crossed helical gear

Hi, i need to reproduce an internal crossed helical gear as you have made in your presentation picture.
I circled the connection i need to reproduce in the picture below :

I don't succeed to reproduce those gears with the pluggin, please could you explain how you did it ?
Thank you for your time,
Yllesia.

Feature Request - Hypoid Support

Hi,

As the request reads - Any plans to add support for Hypoid Gear creation?

Add support for the custom feature API

AutoDesk put out a preview API for custom features earlier this year. https://help.autodesk.com/view/fusion360/ENU/?guid=GUID-FA7EF128-1DE0-4115-89A3-795551E2DEF2. I know a few people have previously requested that this plugin be able to update after creation (#24, #23). It would certainly be more convenient than deleting and re-creating, especially if there is any geometry built onto the gear. With this new API that should be possible. I know that the API is still in preview, but it could be prototyped in a branch until the API moves out of preview.

Adding the output of information about the geometry of the gear in the setting and advanced windows

Hello, is it possible in your script to create gears so that the "info" item is displayed not in a separate tab, but in the "setting" and "advanced" tabs

I'm not good at python programming.

I tried to rewrite the script myself, but I can't display information in real time.

It looks like there is an error in the script that does not allow processing this information

gear = generateGear (args.inputs) is handled by an exception and doesn't seem to allow information to be updated when parameters change

Technically, I understand that it is possible to do this, since there are scripts that display information immediately when changing parameters

Editing the feature doesn't show parameters

Hi, before anything, thanks a Lot for the development of this plugin, it's really usefull!

When trying to edit the feature it doesn't show any thing.

It just show Editing Base Feature but we can't actually edit it!

Im not used to work with plugins on Fusion 360, so is this normal or is it a Bug?

Addendum & Dedendum settings not working

I haven't seen anyone have this issue anywhere, but when I try to adjust the Addendum or Dedendum factor it has no effect on my gear. Is this supposed to be adjustable? I'm running Windows 10 and the latest version of Fusion 360 as of 05/30/20.

Proper internal gear calculation

The current internal gear calculation I implemented is wrong. Maybe someone else knows how to do it.

Gear Information appears blank until a change is made

Gear Information appears blank until a change is made. This does not happen when opening the dialog for the first time.

Error when generation Gear in direct Modeling mode

Gear generates fine. Sketches do not get hidden. Probably happens in the merge code.

Gear does not update with user parameter change

Title says most of it. I'd like to be able to adjust the features via user parameters that can be changed later, but it doesn't seem like this is at all possible. Can this be added?

Help or docs?

Hey, I m trying to generate a worm gear and a gear rack with this, but I am failing ... Is this even possible and if so, is there any help on how to do so?

Error message when command is created when Helix angle is 0

An error message appears when the Helix Angle is set to 0 when the command is created.

Inputs not persistent through undo

Persistent inputs revert to their previous state after undoing a gear. This is very annoying, as you usually undo a gear to make changes to one parameter, and now have to re-enter everything.
This happens due to the way inputs are saved in attributes, and attribute changes get included in the undo stack.

A solution would be to save the Inputs in the add-in and only load from attributes when starting the add-in for the first time.

Add Support for Profile Shifting

Profile Shift is a useful tool for adjusting the working distance of Gears as well as preventing interference with internal gears.

Addendum/Dedendum Radial Gear Standard

First time basically using GitHub so Im probably doing this wrong.
But I noticed while I was trying to edit the addendum and dedendum of a gear under the radial setting that nothing happened.

gear.addendum = gear.module
gear.wholeDepth = 2.25 * gear.module

I believe should be:
gear.addendum = addendum*gear.module
gear.wholeDepth = (addendum+dedendum) * gear.module
