Making "Continuous Rectangle Table Base" with help of 2D sketches only.
Material : Sq. Tube (mm) 25*25*2thk.
Overall Dimension (mm) : 1000*500*400

Step 1: Starting our Model.
Open your 3D software. Start 2D sketch.
-
Step 2: Starting with Base Profile.
Draw an open sketch as shown in picture.
Create a new plane "Normal to curve - at a point"
Draw raw material cross section at new plane. In my case I am modelling this using section of 25*25*2thlk. steel tube.
Use Sweep command to create our 1st profile.
Cut the profile at 45° as shown in above image.
With this our 1st profile is done.

Step 3: Modeling Next profiles.
Start the next sketch at point of earlier profile as shown above. Dimension at this point need to be calculated for gap. For this project I am using dimensions above.
Follow the earlier procedure of ;
- Create a new plane "Normal to curve - at a point"
- Draw raw material cross section at new plane.
- Using Sweep command to generate profile.
- Cut the ends of new profile at 45° as shown above.
Follow the same procedure for all elements till rectangle is completed as shown below.
I have used colors to identify 6 different profiles so it can be easy to understand.

Step 4: Checking Overall Dimensions
After completing the model. I just ensured if I have modeled my job with the dimensions I have decided. As you can see above, Overall dimensions perfect. The gap is uniform at where it is present.
Though I modeled it with multiple errors while creating each profile. The gap was more at some section. Profile is length out of box dimensions. But finally I managed to get is perfect.
This is final render I have created using keyshot. The 3D .step file is uploaded on my profile. You can check it out there also.
# There is another project I have made for similar work, though it uses 3D sketch and complete table is created in single SWEEP command.
Below is picture of same for your reference.
Thank You...
