How to learn 3D modeling*? I feel like I don’t know where to start
Try Microsoft Office Visio 2007; I see it has it, but I’ve never used it to draw anything. To create 3D drawings, one must first have a three-dimensional concept in mind; one has to think about it first before drawing it.
I have a strong sense of three-dimensionality; I just don’t know where to start
One needs to be conscious of this, have a good spatial imagination ability, and can use the polar axis in CAD for drawing
Personally, I feel that SolidWorks is easier to get started with than ProE, so I prefer using it. ProE seems to have quite a lot of functions!
Creating 3D drawings with CAD is not difficult at all! Everyone should be confident and, most importantly, learn to invert coordinates using the right-hand rule.
Compare with the actual object, draw more and practice more*; success will come naturally with enough effort
When it comes to 3D modeling, if it’s a matter of transforming coordinate axes, then the principal plane is the xoy plane. Therefore, to draw shapes in different directions, one needs to continuously transform the xoy plane; it’s also possible to avoid such transformations, but in that case many point coordinates have to be determined, and many of the coordinates of points in three-dimensional space are difficult to calculate. Personally, I find it a bit challenging to use CAD for 3D modeling – it’s hard to convert between different planes. I wonder if it’s because I haven’t practiced enough. I’ve heard that SolidWorks and PRO-E are difficult to install; I tried to download PRO-E from the Internet before, but I wasn’t able to install it, so I ended up using CAD for 3D modeling.
I’ve heard that SolidWorks and PRO-E are difficult to install. I tried to download PRO-E from the Internet in the past, but couldn’t get it installed, so I ended up creating CAD drawings of the 3D shapes. What are the differences between CAD 3D drawings and those created in SolidWorks? Is the latter a bit easier to learn?
