I think you skipped over the most important part, which is aligning the 3d scan to planes/coordinate system

@forgeproductdevelopment 2 года назад

A very good point! This model came pre aligned, as it was saved from an existing model for the design completion, but you are right. I will try to make a video on alignment and coordinate systems.

That’s awesome! One tip for reverse engineering from scan data: You don’t need as many points as you think. Accuracy of the point and knowledge about how the part was manufactured can go a long way, and help reduce file size. Good luck!

@Asynchronous- 5 месяцев назад

Overall a very good educational video to reverse engineer a scanned part. But here are my 2 cents to the process shown in the video. The first step should always be to check and fix alignment of the origin aswell as checking the geometry itself if its warped or crooked, ie squareness and parallelism of the main surfaces. In general you should really only use the scanned model as a reference to create an actual parametric model. All the sketches and planes you did should not be actually used for extrusions but used for construction reference. This way you can use them for defining actual real measurements for a fully adjustable part that can be edited like the original part. It takes a little bit more work but its nice to have the fully adjustable features for the whole part. That way you can customize it again and it wont be locked to the scan's dimensions which, in the real world, are always off, have weird decimals and never 100% accurate geometry. (In this example the angles are off and most of the dimensions have weird decimals) FYI if you do it this way the mass of this model is 100% accurate with the provided mass it should be. Thanks for the video!

@ryanpatton1795 Год назад

Liked and subscribed. The algorithm has a funny way of showing you things you need when you need them. Can you please, PLEASE, do this with more organic STL files? I have to recreate an instrument and the curvatures/surfaces are killing me. Thank you

@JB-ri6zp Год назад

That's because it literally listens and watches you ;)

@hahahayi1017 Год назад

This method only works with simple parts like the one he’s done here, you could try to just import your STL file as a solid body instead of a surface body.

@forgeproductdevelopment Год назад

Would you mind sharing the file (or something similar). I would be happy to give it a try.

@forgeproductdevelopment Год назад

If you do not need to create perfect geometry, using the stl as a body may be a good option. It depends a lot on what you need out of the model.

@WD1271 2 года назад

Just discovered your video and really liked it. I learned a lot. I have a problem where occassionally a solid body is stuck on transparent and nothing I do can change it back to opaque again. I'm using SW2017. Can you do a video on that?

@forgeproductdevelopment 2 года назад

Hmmm a video would be tough unless I can recreate the problem. I have seen similar things where surfaces will go transparent and look like sections of the model are missing. It usually resolves by restarting Solidworks. You can also try "ctrl+Q" to rebuild the feature tree and force it to solve the body again. It may also be graphics compatibility issue with the older software version. Updating to whatever version you can may help.

@DustyLane Год назад

Josh thanks for this video. I need to import several drawings into solidworks and remodel them as the original designer used blender. Im having issues with scale when importing. If I import the model into blender the model is the proper scale. But if I import it into solidworks the entire model is super small. Changing the import options from CM, MM, M, Ft, In doesnt do anything for importing. Any tips?

@forgeproductdevelopment Год назад

Hmm, sounds like my first suggestion of changing the import units didn’t work. What is the file type you are importing? If it is3D geometry and you know what size it is supposed to be, I might just import using any units, then use the scale command and play around with the scale factor until it is the size it is supposed to be.

Kar98K! Now you are in my world! Is this for work or fun? Let me know if you want some help on it!

@Rycamcam 2 года назад

Why did you extrude the circular feature boss 2-ways? First, you did up to next (downwards), then you extruded up to vertex (upwards). Couldn't you have only extruded up to surface considering the circle sketch was already sitting on the correct plane?

@forgeproductdevelopment Год назад

For the first extrude, we could have extruded down to the surface of the body, since it was one continuous surface. For the second extrude (the cylinder) I wanted to use a point from the .stl to stop the feature. There are lots of ways you could have done it, and most would be valid.

@alimortadarabab2513 2 года назад

relations must be deleted after defining them and getting the right dimensions from them, so the new model is not attached to the stl. file

@forgeproductdevelopment 2 года назад

I think this is a great tip, and a step I could have shown in my process. It would have taken more time in the video to dimension and re-constrain the sketches, but that would be best practice.

@georgeduke481 2 года назад

I have a complex STL drawing which can only be imported in SolidWorks as a Mesh geometry. Any tips on how to reverse it to a solid body?

@juangarcia-fc2uf Год назад

have you tried to use geomagic for solid works or something like that? it would work good for that

@hahahayi1017 Год назад

Import it as a solid body, you can choose to do that in the options tap

Does it need to be reverse engineered or just converted to a solid?

@forgeproductdevelopment Год назад

This is just a basic example to show how to pull information from the STL. The techniques can be applied to any feature to model more complex geometry. Also, keep in mind that Solidworks is not always the best tool for the job. For reverse engineering really organic models, other software may be better.

@@forgeproductdevelopmentcould you point me to said software? Really struggling with an organic part I have to reverse engineer.

@forgeproductdevelopment 10 месяцев назад

@@D1S0- The “Power Surfacing” add on for SW is a good option, if you want to stay within SolidWorks. Also, SW has browser based tools that can be used for SubD, but I have not personally used those. Rhino and Blender are less expensive tools for surfacing/organic work. There is a learning curve and you will have to import/export. If you can share the model, I would be happy to take a look at it for you. I have been meaning to do a organic stl RE video.
