    Shortcut to Export a DXF File?

    You do need to have SAVED the part file before you can make a drawing.

    Computer Crashed how to proceed?

    Or just contact support - they'll release your licence activation at the server and can tell you the latest version that your licence is entitled to. https://www.alibre.com/alibre-customer-support-ticket-entry/

    Post Processors for Atom3D or Should I Update to the CNC Versioning?

    System options -> Interoperability -> STL/ZPR as well as the settings this includes a check box for 'show options on export'

    Post Processors for Atom3D or Should I Update to the CNC Versioning?

    If circle is showing as square in the exported STL - you need to review the STL output settings. Try starting with the values shown at https://help.alibre.com/articles/#!alibre-help-v27/stl-export-settings MeshCAM can also accept STEP input which shouldn't suffer the same problem.

    What determines the Item number in the BOM?

    Typically it's best to delete and re-create the callout. You can manually override, but then you have to remember to edit in future. May be a peculiarity of exploded views - they don't update in the same way as other views after editing the assembly (from what I recall).

    Recovery of user settings

    Sorry - I don't know how to edit the file, nor how to locate corruption in it.

    Recovery of user settings

    Yes - with Alibre closed, rename the existing User.NET.profile_27 file to somethign else (e.g. User.NET.27old ), then rename the User.NET.profile_27.bak by removing the .bak Then re-launch Alibre. BUT if there was a problem with the old file, then you'll have exactly the same issue again.

    Post Processors for Atom3D or Should I Update to the CNC Versioning?

    If controller is GRBL based, use the GRBL posts for MeshCAM - check documentation for your controller as to what file extension it expects for the g-code file. As a newcomer to CNC I suggest start with simple operations - don't try to do everything in one go in your first project. build up slowly.

    Post Processors for Atom3D or Should I Update to the CNC Versioning?

    The list of post processors was taken from my own MeshCAM installation. 1. There will be a difference, actual times will vary depending on complexity of the job and power of your computer. 2. You may need to change the file extension - different controllers expect different file extensions...

    will Alibre work well on this system

    A lot depends on how large/complex the models to be handled are. If I were to point to a 'weakness' in the spec given - I'd say that maybe more RAM would be useful - but that's only going to be the case if working with very large/complex models. I have 32GB on my main system and only 16GB on...

    will Alibre work well on this system

    I would expect pretty good performance.

    can't get an assembly contraint to work

    Looks like possibly only one member is selected for the constraint (other has been destroyed by an edit of the part perhaps).

    Exactly what can be referenced in reference planes/axis/points.

    Maybe you can clarify what you mean by "not noticed", and "sketching does not see axis"... What is it you want to do with the axis? I can constrain to and dimension from axis in sketch mode.

    Exactly what can be referenced in reference planes/axis/points.

    Axis is noticed when sketching, BUT you may have to adjust point of view slightly to be able to select the axis if it is hidden by an edge on plane or by the existing solid. Rotate workspace a little, or pan/zoom to see where axis extends beyond model.

    Exactly what can be referenced in reference planes/axis/points.

    No need to create 2nd plane - use the plane or face that you will sketch on to create axis (must be done before entering sketch mode). No need to project the axis - just use it directly in the sketch to dimension from or constrain to (any projection needed happens automatically)

    Exactly what can be referenced in reference planes/axis/points.

    What are you actually trying to achieve here? You can add a point where Axis 5 intersects Plane 5. Thought there are simpler ways to position a point there... Examples of uses for planes & axes - to define revolves or mirrors, as intermediaries in defining difficult geometry.

    draw gear to a set diament

    Yes - there are simple equations which link number of teeth, pitch diameter, outside diameter and DP or Module. One web page showing the basic equations is https://www.engineersedge.com/gear_formula.htm

    draw gear to a set diament

    Well gears have to have an integer number of teeth. If using gears from a standard series you'll be limited as to centre distances that are possible. If 3D printing gears then you could use a non-standard DP or Module value, to give more freedom on centre distances. If there are 3 gears in a...
