  1. Hello, I'm still using "Curves->Bi-tangent segment", and it still works for me. See attached picture. It still works without any snap filter. Best Regards, Mario

    Installing Local Help in 2018.1

    Hello, I am not sure if there is a local help file at all. The menu shows the following point: File->Help->Help (Open the online help for Inspire). Best Regards, Mario

    Create a cylindrical surface part

    Hello again, I have another suggestion. You can sketch and extrude 2 semicircles (different parts). You can also combine them in the end by boolean operation. See picture sequence. Best Regards, Mario

    Create a cylindrical surface part

    Hello, Unfortunately I do not know any direct way. One could construct an open cylinder and make a surface out of midsurface. (see picture). Best Regards, Mario

    Breaking in model

    Hello, Do you have any constraints on the "disconnected" non design space? If not, the part is obsolete. Best Regards, Mario

    Convert surface into volume

    Hello, As you can see in the model browser, there are 2 surface parts (flat surface, instead of cube; nb. 6 and 6.2). Since the mass is zero, they also have no thickness. If the object has still all surfaces to build a enclosed volume, than you can try to "Boolean->Combine->Pick the part(s) in browser->Press "combine". Otherwise you have to check it for open holes, close it and try Boolean. Best Regards, Mario

    Mirror a polynurbs

    Hello, I can't detect the symmetry plane in your model for the polynurbs and for me it seems to be broken. But in general try the following: 1: Mirror the polynurbs object with standard mirror tool 2: Combine both polynurbs objects with Boolean - Combine Take a look at the pictures. I hope that's what you meant. Best Regards, Mario

    Point to apply gravity or acceleration

    Hi, I have used the acceleration panel to create the load, so it is not the global gravity load. Best Regards, Mario

    Point to apply gravity or acceleration

    Hi VirgileV, It's like described in the user guide (help). "g-Loads are applied to the entire model rather than a part, and are specific to a load case. If you delete the part where the g-Load is applied, it remains in the model." I have tested it on a small example, I have deleted the part, where the G-Load was attached and the load still remains in the model. It is a little bit confusing, since it does not matter where you put the load. It seems it is for graphic positioning only. Best Regards, Mario

    Pause the computing ?

    Hello, As far as I know, it isn't possible to pause a running task. Try to change the priority of the solver task (task manager). Best Regards, Mario
  11. You can use combine also on a "intersect" entity, but I can't see any difference. Intersect combine the surfaces automatically. If you want to use e.g. the "Trim" command on more then one surfaces at the same time, than you use combine. After intersecting is is also possible, without combining. Maybe Envolve handle this closed volumes as solids, but in the end, it does not matter. Section views are always open, trimmed bodies becomes closed.
  12. As I have written in my topic, it is always a hollow space enclosed by surfaces.
  13. Hello, Strictly speaking, there are no solids in Evolve. Only volumes, closed by surfaces. As you say, you get these volumes by closing all openings. Take a look at the tutorial for a car wheel: Best Regards, Mario

    Use of dimensions in Evolve

    Hello, Please keep in mind that this is a design software, not really a CAD program. But nevertheless it is possible to create rudimentary dimensions. These dimensions can be positioned, are associative or non-associative. You can switch from modeling to drafting environment and automatically create views. Take a look at the attached pictures. Best Regards, Mario
  15. Hello, We are here in the Inspire (not Evolve) forum. INSPIRE: Use the "Cut Modify" Tool to slice solids by planes. See attached picture. EVOLVE: For Evolve you can use the Trim command: To delete the construction tree, use the command Edit->Collapse Construction Tree. You can save the source objects by answer "No" in the dialog. To have the construction tree is in general a big advantage over other modelers. Best Regards, Mario
  16. Hello, I have a question regarding the presentation of results. Find attached two pictures of the same result presented in Inspire and Hyperview (from scratch directory. fem & h3d). You can see the result of a screw pretension. The stress distribution look extremely different and i'm a little bit surprising. Is there any reason for that? Best Regards, Mario Pretension.stmod
  17. Hi Felix, The asymmetry is not the problem, but the stress distribution does not look plausible. Corresponding to the pressure cone (area) of a screw connection, the highest load should occur at the top. Best Regards, Mario
  18. Hi Felix, Thank you for the explanation, now I can understand it. Unfortunately, this does not improve the plausibility of the result. Best Regards, Mario
  19. Hi again, The "Autocalculate Meshsize" of both parts is switched off and min. is 1mm, max is 5mm. There is nothing more to do, only run a calculation. If it is not comprehensibly, then i can send also results (but the file is much bigger, since you need also the h3d for Hyperview). Version i'm using is Inspire 2017.3.1 build 8625. Best Regards, Mario
  20. Hi, The file is already attached in the post. (Pretension.stmod) Best Regards, Mario

    Optimization Error

    Hello again, Here is an updated model and example optimization. Find attached the model file. The example is a topology optimization (objective: max. stiffness, % of space volume). Best Regards, Mario model0817_CleanUp.stmod

    Optimization Error

    Hello, I would consider the following things: The constraints and force are not connected to the solids (non design), since they are attached to free points. This will be the reason for the error message. All longitudinal and vertical inner beams are modeled twice There are a lot of intersections and so it is a problem to find clear contacts for the solver. You get a warning message before the run (in my version 2017.3) At all, try to model a flat solid plate between the two non design borders. Then you get a idea on how a optimized support structure looks. After clean up point 1 and 2, I could do a structural analysis (see attached picture). I did not try to perform an optimization, since it is useless for me. Best Regards, Mario

    Hi Arjun, Thank you for the video, but the question is how to snap midpoints to midpoints (of edges)... Best Regards, Mario
  24. Mario


    Hello, you are right, my retangles had the same height. Then it snaps to the midpoint. If you want to snap at the top midpoint you have to move the local axes to this location first. My fail, sorry. Best Regards, Mario
  25. Mario


    Hello, you have to switch on the "Snap to midpoints (or press ALT)" snap option (all others off). Use the "Translate" tool to move the rectangle near the target location and it snaps to midpoint-midpoint. Best Regards, Mario
