How to solve problems encountered when modifying or editing elements in RevitWhen modifying or editing graphic elements, various warnings often pop up. So how can we solve these problems? Today, we bring four solutions to the problem. Please read on!
1、 Cutting or connecting geometric shapes failed
When attempting to cut or connect geometric shapes, a warning is displayed and the geometric shapes cannot be regenerated correctly.
Warning:
There are several similar error messages for this condition, such as:
Unable to cut an instance of __AI_T_SC_0_ from outside the wall.
Cannot cut entities with instances.
The roof cannot be cut.
Cannot cut connected elements.
Unable to keep elements connected.
Question:
Revit must be able to create fairly accurate models according to building proportions. The application has built-in implicit assumptions about the scale and accuracy required to generate practical building models.
On the large scale side, there is a limitation that the graphic must be within 20 cubic miles.
On the small scale side, when cutting geometric shapes, the application requires precise alignment of faces and edges. Slight misalignment during alignment may render geometric shapes invalid, leading to the failure of cutting commands.
Another small scale requirement is that the geometric shape cannot be less than about 1/32; (0.79 mm). This means that the edges, width, and radius of the effective geometric shape must be greater than or equal to that length. In cutting, the resulting geometric shape must meet this requirement, otherwise it will be considered invalid. Two independent geometric shapes can be effective, but when cutting from one geometric shape to another, the resulting material edge or volume does not meet the minimum length requirement.
In the following example, represents a condition under which cutting will result in geometric shapes less than 1/32; The requirement represents a condition under which the geometric shape to be cut is smaller than the requirement.
Solution:
Adjust the size or position of the graphic elements to address error conditions. Possible solutions include:
Move a connecting/cutting element to ensure that the generated or cut geometry is greater than 1/32;.
Find combinations of graphic elements that may cause slight inaccuracies, which may be caused by other conditions, such as:
Small rounded corners or chamfers in some geometric shapes.
A cylinder or rotating surface that is slightly misaligned between two parts of the content.
The slightly sloping surfaces at the top/bottom of the element, such as roofs and floors, intersect very closely with other geometric shapes.
Slightly deviate from the axis in the sketch (use the snap function to adjust).
Check the measurement values of the model geometry to ensure that the distance between the relevant elements is less than 20 miles.
2、 Cannot cut instances from outside the wall
When you move an element centered around a wall and cannot regenerate the geometry correctly, an error will be displayed.
Error
Cannot cut
Question:
Revit cannot regenerate geometry to display moved model components.
If Revit is unable to correctly regenerate geometry after moving doors, windows, or other similar wall based components, this message will appear. If you move the window to the door in a plan view, this situation may occur. Revit cannot cut both door and window instances simultaneously. In addition, if the component is dragged or the wall is shortened to the point where it cannot support the component, thereby moving the component outside the wall, this error will also occur.
For example, this curved wall supports a door. When you change the wall in this way, it will no longer be able to support this door, and an error will occur.
Solution:
Cancel changes or delete instances.
3、 Deleted graphic element
If you attempt to paste an element into a location without the correct body, this warning will be displayed.
Warning:
The graphic element has been deleted. Use“ Edit and paste graphic elements; You can keep them.
Question:
Revit requires copied elements to have appropriate bodies. For example, windows require walls, and markings and dimensions need to reference elements.
Solution:
If you attempt to paste an element into a location that does not contain the appropriate body, you will see this message. Click“ Cancel” The warning message can be deleted. Click“ on the ribbon; Edit and paste graphic elements;. In“ Edit and paste content; In mode, place the copied elements onto their appropriate host. Click“ Complete” To complete the pasting process.
Tip:“ Align Paste” Tools are not provided; Edit and paste graphic elements; Button. If this message appears, you can perform a cancel operation and use“ instead; Paste” Tools.
4、 Cannot paste the selected content
This issue occurs when you attempt to paste elements or clipboard contents into an unsupported view.
The following are examples of paste operation restrictions:
Paste model elements (such as walls) into drawing or legend views
Paste tags from one view to another view
Paste the view reference to another view
Paste elements from the model into the family
Error
The selected content cannot be pasted in the
Unable to paste the current clipboard contents to
Solution:
Try pasting into another view (such as a plan view, ceiling projection plan view, or 3D view). Another method is to create a new element instead of pasting the element that has already been copied to the clipboard.
