I'm trying to do an align operation. I start by selected the center of the bottom of a vertical aluminum extrusion. I then select the desired destination, which is the center of the flat top of another object. Having selected that destination the align dialog is ready for me to click the OK  button. But after I click the OK button the dialog disappears (as expected) but nothing happens. The selected object doesn't change position, it NOT aligned as requested. There is also no error message or anything to indicate why it didn't move. Now, you can see that the body I want to move/align is a sub-object of the component that I want to move. Is that the problem? What do I have to do to make the desired alignment?

else if (ent is Autodesk.AutoCAD.DatabaseServices.Surface s) { surfaceCount++; // 使用 GetMassProperties() 方法获取质量属性。 // MassProperties 类型现在可以被识别。 using (Autodesk.AutoCAD.Geometry.MassProperties mp = s.GetMassProperties()) { if (mp != null) { area = mp.Area; } } } The type or namespace name "MassProperties" does not exist in the namespace "Autodesk.AutoCAD.Geometry" (is a missing assembly reference the problem?). 'Surface' does not contain a definition for 'GetMassProperties', and no accessible extension method 'GetMassProperties' accepting a first argument of type 'Surface' could be found (are you missing a using directive or an assembly reference?)

Hallo zusammen, wir arbeiten im Büro aktuell mit Revit und RIB iTWO für die Mengenermittlung. Da ich noch neu in iTWO bin, suche ich bezahlte Online-Sessions oder einen Austausch mit erfahrenen Anwendern. Wenn jemand Interesse hat, meldet euch bitte gerne bei mir.

Hi need a help to make a lisp. 1. User will pick the big line first. 2. Then user will pick the small line. 3. User will enter a percentage value (%). 4. Program must find the endpoint of the small line that is closest to the big line edge. 5. From that endpoint, program should draw a perpendicular line to the big line (connect small line to big line). 6. Then program must divide this connection line using the entered percentage (measured from the big line toward the small line). 7. Find which part (big percentage or small percentage) is longer. 8. Use that longer value as offset distance and offset the big line in the direction away from the small line. 9. Where this offset line meets the connection line — trim the small line at that intersection. 10. Final result: small line is trimmed based on the percentage and the perpendicular offset from the big line. This is my idea, i m sure there would be different concept to reach the result better way 🙂 thank you (defun c:SmartTrim ( / bigEnt smallEnt pct ) (princ "\nStep 1: Pick the BIG line.") (setq bigEnt (car (entsel "\nSelect Big Line: "))) (princ "\nStep 2: Pick the SMALL line.") (setq smallEnt (car (entsel "\nSelect Small Line: "))) (setq pct (getreal "\nEnter Percentage (e.g. 25): ")) ; ; ; ; ; (princ "\nSmartTrim proceess Compleated sucessfully.") (princ) )

**In reactive compression molding, why do we see different filling animations under the same material and process conditions?** In the left animation, the circular disk is shown as being filled directly. In the right animation, there is an additional step where a cylindrical shape is compressed into a disk. What causes this difference in animation behavior?

HI! I want to get the value of ObjectID which is assigned automatically to 3dsolid,but I can't... please help me private string GetAutoObjectId(DBObject dbobj, Transaction tr, ObjectId propSetDefId) { var psId = PropertyDataServices.GetPropertySet(dbobj, propSetDefId); var propSet = tr.GetObject(psId, OpenMode.ForRead) as PropertySet; if (propSet == null) return null; foreach (var name in new[] { "オブジェクトID", "ObjectID" }) { try { //int pid = propSet.PropertyNameToId(name); var value = propSet.GetAt(propSet.PropertyNameToId(name)); if (value != null) return value.ToString(); } catch (KeyNotFoundException) {} } return null; } Before this code,  I add propertyset to Entity. using (Transaction tr = db.TransactionManager.StartTransaction()) { var dictPropSetDefs = new DictionaryPropertySetDefinitions(db); if (!dictPropSetDefs.Has("ID", tr)) { MessageBox.Show("プロパティセット定義「ID」が見つかりません。"); return; } ObjectId psdDictId = dictPropSetDefs.GetAt("ID"); PropertySetDefinition propDef = tr.GetObject(psdDictId, OpenMode.ForWrite) as PropertySetDefinition; foreach (SelectedObject so in selectionResult.Value) { Entity ent = tr.GetObject(so.ObjectId, OpenMode.ForWrite) as Entity; if (ent == null) continue; if (!ent.ExtensionDictionary.IsValid) ent.CreateExtensionDictionary(); PropertyDataServices.AddPropertySet(ent, psdDictId); } tr.Commit(); }

Suggestion: When selecting an Appearance, if it's not downloaded but the user clicks it, auto-download it rather than making the user move mouse to the download button, then moving it again to select the appearance as clearly the user wants to use that one. Currently clicking it does nothing and extra click and mouse movements are required. Thanks

Hello, I would like to ask for guidance regarding a routing constraint in my current AGV model. In this scenario, **adding new paths is not an option** , so I need to handle route permissions using the existing paths only. The intended logic is as follows: * **If the AGV is empty** , it should always be allowed to pass under the station, regardless of whether an item is present on the station. * **If the AGV is loaded and the station has an item** , the AGV should _not_ be allowed to use the under-station path and must instead take the lower bypass path. * **If the AGV is loaded but the station has no item** , the AGV should still be permitted to pass under the station. I would like to confirm whether such **conditional path access** can be implemented strictly using the existing path network, without adding new paths. If so, I would greatly appreciate any recommendations on how to structure this logic, or which triggers/delegates would be most appropriate. Thank you in advance for your support. @moehlmann_fe

Hi, I am a regular Civil 3D user and asking questions here time to time.  I am wondering what is the best way of learning, specially the part related to Pipe Networks.  Online resources ok but looking for regular attending class in Vancouver BC area. Regards, Ralph

Hello everyone, is this good news? I think so. Google is rolling out its Forums tab in its search engine. It's not yet available in all countries, but some people have already seen it. You can try this link. This is great news because I hope this new tab will bring more visitors, especially to the Autodesk forums.

Hi everyone. I know how to make the grid show in the viewport, but I noticed that every time I open a new project, the grid is hidden by default. Not sure why this could be. I can easily turn it back on, but I'd rather avoi9d having to do that every time I open a new scene. Anyone know a fix? Thanks for the help!

I've received a new laptop with new AutoCAD installed, and the Properties Table is too small, I can't even read anything. Could you please help me to make the text size bigger?

What might be the best (easiest) way to create this transition between my **daylight general** and my **Daylight bench** subassemblies in my model? If I have to, I can create some blend featurelines and grade them into my FG. **BUT** if there is some type of subassembly that I can region in between these two SA's that would be fantastic.

I have recently performed a set of random response analyses in the X, Y and Z directions separately for a small assembly of two mated housings. In short, while I was receiving reasonable results in two of the three separate analyses, the remaining axis results (X in this case) were anomalous. Specifically, the maximum von mises stress from the RMS output was an order of magnitude lesser than observed in the other axes (0.1594 MPa in the X-direction as opposed to 5.783 MPa in the Y-direction). By itself, this result wouldn't necessarily be problematic or erroneous. However, for the displacement results, the displayed gradient shows mostly solid colour for the majority of the mesh, and with localized extremes in two locations. This is contrary to the expected displacement gradient as shown in the other axes. For comparison, the von mises stress and displacement results from the Y-direction Random response analysis can be seen in the next two screenshots. I should note that different PSD Accel vs. Frequency plots are used for each of the three axes. X-Direction Y-Direction Z-Direction (Note row values of 1.1 g^2/Hz vs. 1480Hz, and 0.1 g^2/Hz vs. 2000Hz are cut off) **I do not have an intuitive feel for how a particular set of how these profiles should affect the stress and displacement results, and so I do not know if these can explain away the seemingly anomalous results I am seeing in the X-direction Random Response.** **I appreciate any guidance or feedback on how the X-direction Random response results could be so different from the other axes, especially if it is not related to the dynamics setup profile values.** _**Further context on the analysis setup:**_ A view of the model's full setup and UCS used for each of the Random Response analyses can be seen below. Bolted connectors between the front and rear housings, using bearing surfaces (split feature) on the front housing: Two separate concentrated masses are connected to the front housing using rigid connectors: The (4x) mounting interface holes on the bottom of the rear housing are connected using interpolated rigid connectors on each hole (with bearing surfaces on both upper and lower faces of the flange), and rigid body rigid connectors to the main constraint and load point. A surface contact is added between the front and Rear Housings: Mesh Controls had also been added to the bearing surfaces and internal diameters of the bolted connection, and mounting interface holes: The Damping and Modal Setup is as follows: The Load and Constraints have been setup as follows: Finally, the Dynamics setup was as follows:

Does anyone know why PDF export is not printing text correctly, while Printing does? Revit '25. PDF export Print and mind you I have a bunch of 'random' issues like this between BOTH operations, using Bluebeam PDF and nothing is obvious as to why this is happening. Repairing Windows itself seems to have fixed any issue with the Print button.

Can anyone explain to me what I am doing wrong? 1.  Create a New Panel Footprint using Symbol Builder 2.  Use Footprint Database Editor to Create a New Table 3.  Select 'Add New' 4. Use Pick to select the Footprint block name then use Lookup to Find Catalog Data and Click OK 5. Click OK Again Why does this keep happening?  How can I see where the block is saved in Step 1?

Hello, As part of my custom add-in, I need to derive an assembly file to the new or existing part. Below is a code I am using simplified to the basics, it appears to work for a lot of people, but in my case it only works with periodic success, meaning that while it sometimes works, it can also result in "Error 0x80004005", or just outright crash Inventor completely. So far the only consistent logic I was able to observe is that "Error 0x80004005" is being thrown every time I try to use the command in Sheet Metal Parts, but only if at least one Sheet Metal Command (Face, Flange, etc.) has been used, if the document is completely empty, the command appears to be working normally, albeit with the risk of Inventor crashing. Public Sub DeriveAssy() Dim oPartDoc As PartDocument Set oPartDoc = ThisApplication.ActiveDocument Dim oDerAsDef As DerivedAssemblyDefinition Set oDerAsDef = oPartDoc.ComponentDefinition.ReferenceComponents.DerivedAssemblyComponents.CreateDefinition("<< Insert Assembly Full Path Here>>") Dim oPartDef As PartComponentDefinition Set oPartDef = oPartDoc.ComponentDefinition Dim oDerivedAssembly As DerivedAssemblyComponent Set oDerivedAssembly = oPartDef.ReferenceComponents.DerivedAssemblyComponents.Add(oDerAsDef) End Sub I have tried running it on multiple computers, with different files, as well as in multiple versions of Inventor, and the issue is present in every case I tried, which is strange seeing that there is a number of mentions for this command everywhere, even in one of the samples that Autodesk provides, but not a single mention of any issues that I could find. Right now I am mostly curious to see if anyone else ran into any issues trying to derive an assembly to the part with a VBA code, or if anyone else could try and replicate the issues described. Any information would be helpful!

Inventor Nastran 2026.2 has been released. This is my list of changes that I believe are important to users, taken from various sources. To install the update, go to manage.autodesk.com and click “All Product and Services” (on the left or across the top), or use the Autodesk Access app installed on your computer. (Autodesk Access is used to update any installed product.) **Item** | **Change in version 2026.2** ---|--- 1 | Report generation added for Linear Buckling analysis. 2 | Results become outdated when loads or constraints are edited. 3 | Units for additional shell results are now shown when viewing a shell contour result. 4 | The right-click command “Results > Show in folder” in the Model Tree now searches for files with extensions of FNO, LOG, OUT, NAS. If found, File Explorer opens and highlights the first one found. A message indicates if none of the files exist. 5 | Units for rotation results are now shown in the results contour. **However, the results show “deg” when the values are actually radians**. See Unit of rotation results is wrong in Inventor Nastran For previous releases, see * Inventor Nastran 2026.1 list of changes * Inventor Nastran 2026.0 list of changes * Inventor Nastran 2025.3 (No software changes.

I am creating a schedule and have three filled parameters, Length, Width and QTY, and one formula, SQFT. The formula for the SQFT is =roundup((Length+.25)*(Width+.25)/144), but my problem is that Revit is wanting to calculate the roundup per item and not as a total. For example; Qty - 2, Width - 26.9375, Length - 79.5 and the SQFT is calculating as 30.113932 without the roundup in the formula. SO, the answer should be 31, but with the roundup in the formula it is 32 because it is rounding per item and not total. Is there a way around this?

Hello, for everyone. How can I automatically set the name in the sketch so it shows both the part name and the file name, without having to repeat it for every column? Also, is there a way to automatically apply a mask like “PART-XXXX”, where XXXX is an incremental number?

Hi everyone. I am trying to change the location of the detail label. and just to make sure there is no confusion. I'm talking about the label that is located on the view you are pulling the detail from. See image below. When I create a detail with iLogic I can place the circle and I can determine where I want the detail, but I can't see a way to place the B at a decried location, default it is placed at the top but I would like to determine the location. As you can see in the image at about 45 in this case. If there is someone who could assist me with this that would be greatly appreciated. Jarle

Hi everyone, I need help with an issue we are facing with the Fasteners tool in Fusion. Our team already has a large library of bolts, nuts, and washers inside the **Standard Components** folder. These components were previously inserted, renamed, and organized with **our own internal codes**. However, when we insert the _same_ fasteners again using the Fasteners tool, Fusion automatically **renames** the components and ignores our custom naming. Every time we open Fusion for the first time and insert a fastener, we need to rename it manually again. The worst part: * If we **restart Fusion** , all the custom names are lost. * When we insert the fasteners again, Fusion renames them once more. * This also causes **lost references** in assemblies because the renamed components no longer match the previously used ones in the library. We need a way to: 1. Prevent the Fasteners tool from renaming components that already exist in the Standard Components folder. 2. Keep our custom names persistent after restarting Fusion. 3. Ensure fasteners maintain the same reference so assemblies don’t break. Has anyone found a stable workaround or setting to stop this automatic renaming behavior? Any help is greatly appreciated. Thank you!

I have a Steel structure model. I need to get ifc export but while i am trying to get it computer is freezing. I though that maybe export is continue in the backround but export is not finishing. I am in 15 hour now. Is there a any autodesk professional that can help me to get the export?

Hey all, I just looked this up, and according to Google’s AI answer, it says No. I want to know if it’s possible to extract a machine from the manufacturing workspace machine library for use inside the design space. I need a fully functional jointed machine model for evaluating long-reach tooling and machine setups. Ive been using one of the models, I think I got it from Tormach, but it's not joined in any way. My machine is a Tormach 1100M. OR does anyone know where I can get a fully jointed, accurate model of the 1100M with exact machine max travels? Thanks
