Sketchup Import Failed Dwg

[Doretta Castoe]

Iwill try DWG and see how it goes. As for the triangulation, a coworker imported from Max into SketchUP without the triangles using hte 3DS format. Perhaps there is a setting in SketchUP?? I don't know enough about it.

My best max to sketchup workflow (which I found here) is to instance the entire model in Max, export both to DWG format. Open the DWG in ACAD and delete the clone model. Hit "save". Import into Sketchup. Everything will come in as nice, neat components.

To "hide" the triangulation, you can triple click the model in SketchUp so everything is selected, right-click > Soften/Smooth Edges, and use smooth coplaner and adjust the degrees. Although it's probably better to delete the unwanted edges, depending on the model's use in SketchUp.

This plug-in no doubt can import sketchup model to CAD. But when the model is called in into the CAD software, the model scale is messed-up. So basically you can't do anything on the model except you have to re-draw again. But, I found in the sketchup software, you can actually to EXPORT the sketchup model into CAD model and the scale is still same from the original model.

I imported a 2021 Sketchup into AutoCAD 2023 and it works fine, no issues. It imports and turnes it into a block. I wish it would list all the blocks its importing, give us the option to choose which blocks to bring in, and also give us the option to smoothen meshes of some of selected blocks.

There are several possible issues.1. SKP file version is beyond 2014-2019. (You can save the SKP file to a version supported by the app)2. SKP file path contains non-English characters. (You can update the path to contain English only characters)3. Some other issues...

There is an even better solution to this problem. First you need a TIN... which you already have or you wouldn't be here. Next you need to convert that TIN to a multipatch by using the Interpolate Polygon to Multipatch Tool. This tool takes any 2D polygon and 'drapes' it over a TIN surface to make a 3D multipatch of the polygon. If you want to convert the entire TIN, you'll need a polygon that covers the entire TIN. Once you have your multipatch, all you need to do is convert it to a Collada file, using the Multipatch to Collada tool. Once that is done, simply import your Collada file into sketchup and bingo... you're off to the races.

I am importing a truss I created in SketchUp to CA. It comes in with extraneous surfaces. I have redone the SketchUp truss several times; same conclusion with different extraneous surfaces. When highlighting the file to import the thumbnail photo of the truss is perfect, but after inserting into CA extra or missing surfaces appear.

As frustrating is this is (understandable) in my experience, what happens in Sketch Up can only be repaired in Sketch Up. Home Designer has no effect on Sketch Up files so if they are messed up in Home Designer, they need to be fixed or redone in Sketch Up. Something you did or failed to do caused the unwanted result.

Thanks David. I have redone this file several times with different results. As stated above the file is perfect. In various print options it portrays correctly; ie .jpeg and other formats. It becomes corrupted when it is imported into CA. I have assume this since it appears perfectly in all other formats. This is a simple 2D drawing stretched to 1.75" thickness. Not much can go wrong there.

I recreated the file in polylines all in 0.0000 "z" axis. Similar problem when imported into CA. I have contacted tech support for their opinion. Also, I imported truss from 3D Warehouse with same results.

I created the truss three different ways: 1) AutoCad 2D line drawing which was imported into Sketchup, expanded to a 3D SketchUp model and saved; 2) AutoCad 2D polyline drawing which was imported and also expanded to a SketchUp 3D model; 3) created the 3D model in SketchUp and saved. All three models were imported into CA with same distorted surface (faces) results but with somewhat varying distortions.

After many of hours of frustration I stumbled on .3ds format which is a native 3D model file used by AutoCad Studio for rendering. This is one of several 3D model files which SketchUp can export to. I exported all three above SketchUp files using .3ds. All three imported perfectly in CA. See attachment

It allows Tekla Structures users to import files describing 3D geometries as native Tekla Structures objects. Different file formats are supported, such as SketchUp files, IFC, etc.

This document explains the log file entries to help the user troubleshoot the problems described. The log file can be accessed via File menu > > Logs > > Session history log.

In some special cases the importing of these files fails, and the following error message is shown:

Non-manifold cases are usually often occur when there are disjointed objects trying to form one single logic object. Such an example is shown below. You can make a small puncture in any place on the surface of the object and try to add water inside it. If you had only one cube, the water would fill the whole object. However, in the example below, water fills just a part of the object.

The picture shows that there is one edge in the middle of the object that is shared by 4 faces (and exactly the same edge prevents filling the whole object with water). If you manage to create a slot in such an edge, you will get a manifold object (and two edges instead of one original).

Alternatively to creating a small gap between the two cubes, the user could simply separate the objects so that they are not touching. Thus, Tekla Structures will understand that the each cube is its own logical object, and thus import them both.

Coordinates in the log message give more information about the location of the missing faces. Using this information, it will be easier to determine the location of the missing face and to add it, if not obvious by looking at the item in the model.

The item will import as a non-solid in Tekla Structures and it is shown like this:

The error shown in the log file:

WARNING: Some edges in the solid might be missing

This might affect part detailing and drawing view creation

Sometimes, the importing of shapes succeeds and a new Shape is added to the Shape Catalog, usually as a solid. The warning highlights that in the model view, there are some missing edges, as shown below:

You must be careful in these cases, since some detailing operations (such as cutting) might give erroneous results. Similarly, some drawing features might not work correctly, such as for example creating section, detail and curved views. You should report these cases to the local support office.

Sometimes there are shapes that cannot be imported but have no error messages, as shown below:

Info: IMPORTING FILE: ---????? ??????????.skp ---

Info: --- Importing issues: ---

Info: --- Import Geometry, path: C:\ReCIPe\SketchUp\Models\ItemErrorDocumentation\????? ??????????.skp

ERROR: --- Tried to import file: C:\ReCIPe\SketchUp\Models\ItemErrorDocumentation\????? ??????????.skp

ERROR: --- Import Geometry failed! No valid Brep GUID ---

Info: BrepStorage reading for guid: "" failed

Info: --- Importing result: ---

ERROR: a polymesh cannot be created

One reason for this is that the file name contains some special characters. There is a limitation to the import functionality: special characters, for example Cyrillic, will only work if Tekla Structures is installed in a Russian Windows. Try re-naming the file appropriately, for example, with ANSI characters only.

Another reason may be a SketchUp model made in a newer version of SketchUp, which is not supported by older version of Tekla Structures:

IMPORTING FILE: ---SimpleItemTest.skp, External GUID ---

--- Importing issues: ---

--- Importing result: ---

If you are using SketchUp to create or edit solids, make sure (by enquiring entity/group/component) that the solid to be imported has a volume. This usually indicates that the shape is a watertight solid.

If a file fails to import as a solid or at all, you could try importing the file in a different format. You may have access to or may be able to save shapes in more than one supported format (e.g. IFC, DWG, etc). Since each different format uses a different importer, it might be worth trying out importing the files under different formats.

Our library system just put a 3D printer in one of the branches. I have used SketchUp on the library computers for a number of years just to do artsy things. Suddenly, I have the opportunity to actually print something. (I'm really not sure why the libraries have SketchUp installed. But, I have enjoyed using it.)

There is a plug-in available for SketchUp so that it can export STL files. But, the security on the library computers will not allow me to put a file into the SketchUp plug-ins folder. And, the tech guy at the library doesn't think that the IT guys at the library will update all the copies of SketchUp at all the branches just so someone could do 3D printing.

After doing some searching on this website, I found out that I could export a COLLADA / dae file from SketchUp. I would then import that dae file into Blender (The portable version on my flash drive). I could then export it as an STL file. The process appeared to work. I could see my test object in Blender.

Here is what I suggest you try. If you have a file that you can view/edit in blender I would export it as both STL and OBJ formats. Then take those files and upload them to Netfabb ( ) and get a "repaired" file. Have the library try again with the repaired STL and OBJ files. If this doesn't work try to get the exact error message/dialog that the makerbot software is giving them as well as the version of the software that they are using.

Please make sure your object is a watertight mesh. As I have seen its easy to make a surface model in sketchup. A 3D Printer cannot print something in surface. You can also try importing to netfabb to check if the part has errors in it.
