Surfaces¶
Connect surfaces¶
Surfaces toolbar | |
Modify menu > Surfaces > Connect |
This function creates a connecting surface between two surfaces. The transition of surfaces to the connecting surface can be tangential or edge-on-edge.
The following queries appear after activating this function:
Transition tangential on both surfaces?
If you confirm this query with "Y"", the transition of the surfaces to the connecting surface is smooth. Enter "N" and the surface is drawn with sharp edges.
Please click on the surface in the 3D view
The points of the surfaces to be connected can be clicked with the mouse.
This surface?
If the surface that has turned magenta is the desired surface, confirm the query with "Y" Enter . However, if the magenta surface is not the desired surface, respond to the query with "N" Enter . In this case, the query Please click on the surface in the 3D view.
Tip
If the transition is not tangential, the first query is Please select definition. Then click on the border curve in the 3D view and confirm that this is correct.

This function is used to create a tangential transition between two trans, design or free form surfaces. The border curves are retained.
The following queries appear after activating this function:
Please click on the surface in the 3D view
Now select the desired surface by clicking on it.
This surface?
If the surface that has turned magenta is the desired surface, confirm the query with "Y" Enter . However, if the surface is not the desired surface, respond to the query with "N" Enter . In this case, the query Please click on the surface in the 3D view. This cycle is continued until positive confirmation is received for the query This surface?.
Please click on the surface in the 3D view [ Enter = calculate]
Here you can select another surface by clicking on it, or smooth the interior of the selected surface by pressing Enter . If another surface is selected, the query This surface? appears again (as described above).

Join surfaces¶
Surfaces toolbar | |
Modify menu > Surfaces > Join |
This function is used to connect trans, design or free form surfaces with a common border curve. This is particularly desirable in mould construction, so that one single surface can be formed from several individual surfaces, and this one surface can be shaped or manipulated further.
The result is a new surface and the starting surfaces are deleted. The parameters of the new surface (e.g. colour) are transferred from the first surface selected.
The following query appears after activating this function:
Please click on the surface in the 3D view [ Enter = calculate]
Now select a desired surface by clicking on it.
This surface and parameters?
If you confirm with "Y" Enter , the surface is included in the calculations. However, if the query is confirmed with "N" Enter , the query Please click on the surface in the 3D view [ Enter = calculate] appears again. This cycle is continued until positive confirmation is received for the query This surface and parameters?.
Tip
The connecting surfaces must be selected in the order in which they are to be joined.
The Join surface function works for as many surfaces as you wish, if they share a common border curve.
Otherwise, Join surfaces only works for two surfaces at a time. To connect as many surfaces as you want, you have to repeat the function.
Explanation
If the selected surfaces do not have a common border curve, one of these two messages appears in the info window:
First and second surface have no common border curve. Two of the surfaces have no common border curve.
If joining does not work in principle, the following message appears:
Merge surfaces cancelled.
Workshop

Lengthen surfaces¶
Surfaces toolbar | |
Modify menu > Surfaces > Lengthen |
This function is used to lengthen a surface tangentially.
The following query appears after activating this function:
Please select definition.
Now select a desired surface by clicking on it.
Please click the surface on the desired edge in 3D view
Now the side that you want to lengthen must be specified, by clicking inside the surface.
Lengthen surface?
If the surface that has turned magenta is the desired surface, confirm the query with "Y" Enter . However, if the surface is not the desired surface, respond to the query with "N" Enter . In this case, the query Please click the surface on the desired edge in 3D view appears again.
Please enter length
Now enter the new desired length.
Tip
For trimmed surfaces, a new surface is created which joins tangentially. If the starting surface is not trimmed, the starting surface is lengthened.

Invert surfaces¶
Surfaces toolbar | |
Modify menu > Surfaces > Invert |
This function can be used to reverse the normal vector direction of a surface.
The following queries appear after activating this function:
Please click on the surface in the 3D view [enter = End]
Now select one of the desired surfaces by clicking on it. The selected surface is then coloured magenta.
This surface?
Confirm this query with "Y" Enter and the direction of the normal vectors (displayed in red) is reversed. However, if the magenta surface is not the desired surface, respond to the query with "N" Enter . In this case, the query Please click on the surface in the 3D view [enter = End].
Tip
This preparation of surfaces makes it possible for the radius for all surfaces to be entered with the same sign when performing TRIMMEN/RUNDEN. This prevents errors due to incorrect entries.

Outline model¶
Surfaces toolbar | |
Modify menu > Surfaces > Outline model |
Use this function to outline any 2D contour on a surface (e.g. fonts, logos, etc.).
Explanation
Following the query *Which model as border (Select point)? ( Enter = Cancel outline), a corresponding 2D model can be clicked on the reference point and entered onto a specific surface.
However, if you want to delete an existing outline model again, you can do so with Enter . Then click on the surface from which the outline model is to be removed.
Tip
For the options APPLY DIRECT and APPLY AS HOLE, the 2D model must be closed. Changes to the shape and position of the 2D model automatically affect the surface.
Options¶
Apply model direct¶
Use the option APPLY MODEL DIRECT to cut out the surface. The selected model remains.
Apply model as hole¶
The surface is also cut out with this option, However, the model selected is removed from the surface.
Apply model as curve¶
When the model is applied "as curve", a 3D curve is created, which you can continue to edit. The surface is not changed.
Adjust horizontally¶
The selected model is adjusted to be the same width as the surface.
Adjust vertically¶
The selected model is adjusted to be the same height as the surface.
Tip
When you apply the 2D model without adjustment, an attempt is made to apply the model to the surface to scale (1:1). (For free form surfaces, this is only possible with a distortion). If the model protrudes over the edge of the surface, it is scaled.
Workshop
