      How do you punch a hole through the gear? I've tried several different ways and it just won't do it. I want to 3D print it with a D shape hole to fit my motor but it won't let me!

        The resulting gear is an object: double click it to edit it.

            Jon,
            Sorry, but I never got around to adding racks to this version, and it is not like to happen. BUT, there is good news. I am currently working on a "pro" version that will include both racks and worms, plus many other features and enhancements! I know folks have been waiting a long time for this, but the wait is almost over. I know I've stated before that I was "working on it" and had nothing to show for it, so here's a quick sneak peek...

            More detail to follow; very soon. Really. ๐Ÿ˜„

            -J-

              WIN 7 Pro, SketchUp Pro
              Pardon my green-ness, but I installed 1.0 and realized there is now a 1.2
              I installed 1.0 via some link here, NOT the ZIP!
              I want to install 1.2

              1. Where is the 1.2 download link? no download link on that page
                or how to install from zip, since the 1.2 zip extracts an .rb file NOT an .rbz!?

              2. It recommends to uninstall old versions!? HOW is that accomplished!?
                I see nothing in the menus to uninstall extensions.

              3. One thing I noticed on 1.0: the handle(cursor) does not want to latch on to the best inferred handle... it seems to snag around it and latch on to any other close point

              Thank you.

                The link for v1.2 is at the top of the first page of this thread. To install a .rb plugin, just copy the extracted file into your plugins folder (C:\Users*usernme*\AppData\Roaming\SketchUp\SketchUp 2016\SketchUp\Plugins). Restart Sketchup and the plugin should now be listed in "Extension" menu.

                  I see nothing in the menus to uninstall extensions.

                These earlier versions predate the extension managers, so they are installed & uninstalled manually. To remove the previous version, just open the plugins folder, as noted above, and move/delete the older version.

                The plugin does not have any effect on the cursor, so the issue is most likely with Sketchup's limitations working with very small (< 1/64" or 0.39mm) measurements. While programmatically we can work with smaller distances, manual operations using the cursor will not always cooperate. The simplest solution is to scale the model up, make any changes, then scale it back down. It's only a rough workaround, so some geometry may behave unexpectedly when you scale back down.

                Keep in mind that Sketchup is CAM (modeling) not CAD (design), so it has some limitations. This is one of them. Another that has frustrated new users is that objects are collections of edges and faces, so curves are not going to perfectly smooth. It's usually not a problem unless you 3D print a model because the curves will be a series of flat faces and edges, making mating surfaces a bit clunky.

                Good luck and thanks for trying the SPGears plugin.

                  Thank you so much for the prompt answer.

                  YOU MAY WAN TO BE AWARE OF THIS:
                  Unless I keep a separate record(messy) I have no idea what version is running

                  • Extensions Menu shows: SPGears_mjg(no version)

                  so I did this:

                  • in Plugins folder
                    /// I renamed SPGears_mjg.rb to SPGears_mjg_v1.0.rb(may need to remove)
                    /// and I placed the SPGears_mjg_v1.2.rb

                  • Extensions Menu still shows: SPGears_mjg
                    /// but the new ShatfDiameter options shows in the SPGears Parameters dialog
                    /// thus it is running the SPGears_mjg_v1.2.rb
                    /// tried the Shaft Diameter... creates no centered hole for the shaft at all ?

                  Also, creating 2 beveled gears of different radius.. 48 and 24 teeth
                  Number of Teeth: 48 24
                  Pressure Angle: 20 "
                  Pitch Radius: 10" 5
                  Face Width: 3" "
                  Helix Angle: 0.0 "
                  Bevel Angle: 45deg "
                  Shift Diameter: 0.5, or 0.375, or 0.3125 "

                  The teeth line up at the large(outside) face end, but fail to line up at the small(inside) face end

                  • Is this due to incorrect/missing parameters?
                  • (can you point to some instructions?)

                          • Embossing is an interesting idea. Unfortunately, I'm still working through the "must have" list, so embossing will have to go on the "maybe" list.
                          • Rack, Worm, and Ring have already been added; just working out the kinks. I posted a "sneak peek" video earlier in this thread. Check it out.
                          • Calculations and accuracy are greatly improved and I've even added resolution options for speed (low & med res) vs. accuracy/smoothness (high & very high) to accommodate 3D printers.
                          • Web dialog is already planned and will include a few auto-calculations. I'm trying to keep the UI minimal, so it will only include a few details to help with dialing in the params.
                          • Spec dialog and entity properties are planned.
                          • Validation has been improved but increases in complexity with each user input. So, input params will be kept to a minimum.

                        Thanks for the suggestions, and for prioritizing them. Sorry embossing was bumped to the end of the list, but it is still on there.

                        Just in case your next question is "when", the answer is still "soon", but I've had to put it aside for a bit to focus on other stuff. ๐Ÿ˜ž I was shooting for Summer, but now my hope is to get it out by Fall.

                          Yeah, redoing the Spiral-bevels for the pending version was a big hurdle and still isn't perfect. Right now, I have to sneak up on the ideal helix angle to get a proper fit. By adjusting the target angle by 1-3 degs. I can usually clear up interference in the pair.

                          BTW, the pending version draws mated pairs, aligned and enmeshed. It makes the sneak-up process easier, but you still have to examine the tooth contact, close-up and from numerous angles. It needs more work, but I'm pretty sure I can solve it.

                            Why haven't you updated the RBZ version of your entry in the PluginStore ?

                            It's quite straightforward to edit it...
                            But if you need assistance PM me or Rich...

                            You should then add a link in the original post to its Download...

                            It would avoid any ongoing confusion.

                                Good afternoon and thank you for this wonderful plug-in.
                                My question is:
                                Is there an easy way to make different number of tooth gears with same teeth size?

                                  This extension will do that. The number of teeth will determine the diameter of the gear.

                                  There are other gear-generating extensions that can do the same thing.

                                    Thank's Dave, but it's not the result I'm getting.
                                    I made a gear with 36 teeth, if I made another with 18 teeth the diameter is the same and the teeth have duplicated the size.

                                      Hmmm.... I haven't looked at this one for a long time. Looks like you need to know the pitch radius of the gear and let it put in the right number of teeth. I generally prefer to model gears in a more manual way to make sure I get tooth profiles correct. It's not really difficult and I'm assured of getting what I really want.

                                        I would be cool if we have a Modulus and Number of teeth as both factors to construct the gear. That way all gears relate to each others.
                                        Put it here as a suggestion.
                                        Thank you!

                                          New member PhilLeGall has done some work re-coding this toolset.
                                          I've suggested to him that he first posts outline details here, with a view to perhaps publishing an updated version in due course...

                                          Hopefully he'll post here soon...

                                          He would like to contact the original author - but his out-bound PM abilities are initially curtailed.
                                          Perhaps jgrundman could PM him, when he sees this ?

                                            Good morning to all of you.
                                            I'm trying to contact Mark Jason Grundman. I would like to present him with a version 2 of SPGear quite complete.
                                            The new version offers the following services:
                                            Bilingual (English, French), easily expandable for other languages.
                                            Automatically adapts to the SketchUp type (mm or inch)
                                            Draws, in addition to straight gears, helical, conical, helical conicals, chevron gears, hollow wheel gears and globic screws.
                                            The new version performs calculations to correct deformations in the case of very steep propellers (screw cases)
                                            The new version also proposes to draw the adapted satellite gears (calculated automatically) and then place them correctly on the leading gable.
                                            The app filters the compatible settings for each requested case as much as possible.
                                            The new version uses and generalizes mesh drawings (systematic use of add_faces_from_mesh methods)
                                            The new version includes well on the setting of the boring, the size of the flap, the design or not of a rimmed/rim and the direction of rotation of the helical
