Connect adaptive points.
I Adaptive function drawing special-shaped surface process 1 Create a building mass model, create a new conceptual mass, and select a metric mass.
Click drawing Panel > model command > point primitive, and place “model points” on the completed adaptive points in order.
After placing, directly box it, select the filter, check only the reference points (model points), and adjust the offset of the model points in the attribute bar.
I’ll see you in the next issue..
After the connection is completed, frame all points, and click create shape > solid shape to complete the adaptive component family.
Finally, set the material information for the component.

In the example, two polygonal contours are drawn, one of them is rotated, and a simple building mass model is generated in combination with the create shape command to make the required special-shaped surface.
That’s all for today’s sharing.
3.
The order of adaptive points is the order of creating points.
In this modeling environment, click the create command and select the point entity in the reference command bar to draw.
(triangular adaptive points are more suitable for making spherical surfaces.
Then press the repeat operation button to tile and copy to the greatest extent, and finally fill in the vacant part by creating an instance.
Note: during surface segmentation, some triangles will appear, so in addition to making adaptive surfaces with 4 points, we also need to make adaptive models of other shapes (such as adaptive surfaces with 3 points) according to the actual requirements in case of need.
Create 4 reference points in the reference plane.
For each model point placed, it is necessary to set a work plane (4 in total).
Before placing the model points, it is necessary to set the plane of the adaptive points as the work plane.
Most curtain wall or facade components are quadrilateral without special design or requirements of the project.
Click drawing Panel > reference command > line primitive to connect and draw according to the order of adaptive points.
You should choose to place them in the 3D view.
In this way, we have completed the drawing of the special-shaped surface veneer model.
Building mass model processing frame select the building mass model, click split surface, and set the number of UV grids according to the actual situation of the project.
Select the four existing reference points in the plane and click make adaptive to generate adaptive points.

Box the building model with divided surface, select “surface representation”, and check “node” in the pop-up dialog box.
Create an adaptive construction family and create a new “adaptive metric general model” family.
2.
If you want to check 3D snap when connecting 3D views.
Therefore, it is demonstrated here to model with 4 adaptive points.) Create adaptive points based on four existing reference points.
In the case of general complexity, we can use the adaptive general model in Revit to cooperate with the mass model to create the special-shaped surface model.
Place the adaptive construction model, import the completed adaptive model into the building mass model, and pick the nodes on the mass model in order of adaptive points to generate the adaptive mass model.
In the daily BIM modeling work, the facade and curtain wall of some projects need to draw the special-shaped surface, and the veneer of this area is drawn according to the needs of the project.
